ADU Regulations in Nebraska: The Complete Guide

ADU Regulations in Nebraska
The Rivara ADU

Welcome to the vast prairies of Nebraska where rich history, stunning landscapes, and unique culture are part of your everyday life. If you are a proud Nebraskan homeowner, you may be on the hunt for a way to improve your housing situation, find a nearby space for your aging parents, or in search of a good investment opportunity. You’ll be pleased to hear that Accessory Dwelling Units or ADUs, as they’re more commonly known, check all those boxes. These popular traditional housing alternatives are perfect as a unique separate living space, while still residing right on your property. 

Zook Cabins is ready to break down all the nitty gritty details for you and explain each of the regulations regarding ADUs by county and certain municipalities. Let’s dive right into learning!

Are ADUs Allowed in Nebraska?

Are ADUs allowed in Nebraska
The Sonoma ADU

To answer the most pressing question, the answer is yes! Many counties and municipalities in Nebraska allow ADUs in some format. However, it can be more complicated than that, and some areas do not allow them, while others permit them on certain conditions. Because there is no statewide law that dictates the regulations, it is left up to the local level. To find out more, keep reading while we go over all the essential information. 

What Is Considered An ADU in Nebraska?

An ADU is defined as its own separate living quarters with full kitchen, dining, sleeping, and bathroom areas. This can take the form of an attached ADU where a separate apartment or section is built onto a house or an internal conversion, where a garage or attic is converted into a living space. However, the most popular option is a detached ADU where the living quarters are in their own separate building, located close to the primary dwelling. 

Can Park Model Tiny Homes Be Used As ADUs?

The Aspen Park Model Tiny Home

It depends on your zoning.A park model home is our version of a tiny home. Each model is built to RVIA standards, meaning that some counties will view them as an ADU, while others will require a totally permanent foundation in order to be considered an ADU. For the best clarity, we suggest calling your local zoning and planning department to ask about what is allowed.

Can Log Cabins Be Used As An ADU?

Can Log Cabins be used as ADUs
The Wrangler

Yes! Our selection of log cabins can be a great option if you live on a rural parcel of land and are looking for something with that homey, rustic cabin feel for your extra living space. It is important to note that log cabins are larger, and certain models will exceed the size limits in some counties. However, a smaller model starts at 650 square feet, which should be just perfect in most Nebraska counties that allow ADUs! 

Can Modern Cabins Be Used As An ADU?

If the traditional log cabin isn’t your vibe, we have options for you with our sleek, modern cabin models! These have the cozy feel of a classic cabin, with a beautiful modern interior, perfect for a rental ADU. Whether you are opening an Airbnb, or just wishing for the perfect place for family members to stay with you, these might be just for you. As always, check with your local zoning department to confirm the eligibility of modern cabins as ADUs

What is the Difference Between a Prefab ADU & a Modular ADU?

The A-Frame ADU

While prefab and modular ADUs share many similarities, the primary distinction is in the manufacturing and assembling process. Prefab ADUs are usually constructed entirely in a factory and then simply placed on the permanent foundation with the finishing touches. 

In contrast, modular ADUs are built in sections, delivered to the site, and assembled there for the last minute adjustments, and perfect fit. 

Nebraska counties and municipalities do not distinguish between prefab and modular ADUs, so different permits or building processes are not necessary for the different kinds. 

What is the Minimum Size for an Accessory Dwelling Unit?

Nebraska does not have a single statewide minimum size for ADUs, unlike some states that set uniform minimum house sizes, Nebraska leaves these details mostly up to local cities and counties to regulate. That means the smallest allowed size for an ADU will depend on where you’re building, based on local zoning codes and whether the unit is treated as a “tiny home,” accessory structure, or full second dwelling.

Can My ADU be Bigger Than My House?

No, an ADU will never be able to exceed the size of your primary dwelling, as its intended purpose is to complement the house, not exceed it. Typically, municipalities will cap the size at 50-75% of the primary dwelling. 

How Close To My House Can I Build An ADU?

The general rule of thumb is a 10ft rear setback and 5 ft side setback. However, this can vary from county to county, or by zoning area. Your local zoning regulations should offer guidance on this. Additionally, many ADUs adhere to the same setback standards as other accessory buildings like sheds and standalone garages. 

Do You Need A Permit For An ADU in Nebraska?

Do I need a permit for an ADU in Nebraska

Definitely. Because ADUs are intended for living purposes, you will need at least a building permit and probably an HVAC and plumbing permit. For the entire permit guidelines and process, visit your building department and ask for their assistance.

Are There Any Incentives or Grants for ADUs in Nebraska?

At this time, there are no statewide grants or financing programs. This is most likely due to ADUs being relatively new in Nebraska and grants haven’t been developed yet. In the future, there may be more options for homeowners, but in the meantime, reach out at the local level to see if they offer any building incentives or payment plan options. 

Are Zook Cabin’s ADUs Built to Code?

Are Zook Cabins ADUs built to code

Absolutely! No model leaves our lot until it has been thoroughly inspected for code compliance. Our team of designers and builders ensures that your specific ADU will match and even exceed all your local building codes. That way, you can sit back and relax, knowing you are meeting all the requirements.  

Can an ADU Have Multiple Bedrooms and Bathrooms?

Can ADUs have more than 1 bedroom
The Luna ADU

Yes. If local maximum size allows it, you can definitely have a multi-bedroom and bathroom ADU. Many Nebraska municipalities do cap it at one bedroom, so keep that in mind but if your area does allow more than one bedroom, choose from our cozy one bedroom options or a more spacious two bedroom ADU, perfect for a larger group! 

Are ADUs A Good Investment?

Absolutely! Because of their lower prices than a full sized house, and the ability to rent them out in certain towns, customers usually report a fast ROI on a modular ADU from Zook Cabins. Their versatility makes them perfect for you to invest in them and see the return quickly. Whether you are housing your family members or using it as an Airbnb, it is worth your investment. Plus, it can increase your property value when you go to resell your house!

Does Douglas County Allow ADUs?

Yes, Douglas County does allow accessory dwelling units and tiny homes in many zoning districts, especially in and around the Omaha metro, though exact rules vary by location and whether you are inside a city limit or unincorporated area. Douglas County zoning controls accessory uses, including ADUs, by limiting size (commonly no more than about 750 square feet) and requiring compliance with height, setbacks, and permanent utilities. Rental use is generally permitted as long as the ADU is treated as a long-term dwelling rather than short-term lodging, but restrictions can differ based on subdivision or homeowners association rules. To determine specifics like minimum lot size, maximum size relative to the primary dwelling, and setback requirements, contact the Douglas County Planning Department or review the Douglas County Zoning Resolution. 

Does Lancaster County Allow ADUs?

Lancaster County has clear ADU provisions; the county updated its zoning code in 2018 to define and permit one accessory dwelling unit per lot in single-family zoning districts. ADUs in Lancaster County must comply with design standards established by Lincoln’s municipal code when within city boundaries, which typically include limits on unit size (often no more than 750 square feet), owner-occupancy or deed restrictions in some cases, and compliance with lot setbacks, parking, and utility connection requirements. Detached or attached ADUs are generally allowed “by right” in residential districts, although building permits and site plan review are required. To dive into details, homeowners should consult Lancaster County’s zoning regulations and the City of Lincoln’s ADU design standards section in the municipal code. 

Does Sarpy County Allow ADUs?

It is unclear at this point. Sarpy County’s zoning code does not provide a simple published answer for ADUs statewide, but the county does permit multiple single-family residences on a lot if the property can be subdivided. ADUs as accessory residences may be allowable under certain residential or agricultural zoning districts, provided they meet local size, setback, and utility requirements. Because regulations are governed at the subdivision and district level, contact the Sarpy County Planning Department for the zoning designation of your parcel and review the county’s zoning regulations for ADUs. 

Does Hall County Allow ADUs?

Here again, it is not very clear based on current zoning regulations. Hall County has no widely published ADU-specific code online, but tiny homes and accessory dwellings are subject to local zoning review, and many municipalities within the county must approve ADUs on a case-by-case basis with traditional accessory structure setbacks and size limits. If allowed as an accessory dwelling, Hall County’s rules would require the unit to be subordinate to the primary home, meet lot setbacks, and connect to permanent utilities. To confirm if an ADU is permitted on a specific lot and to determine other regulations, contact the Hall County Zoning Department or the planning office of the incorporated city within Hall County where you intend to build. 

Does Buffalo County Allow ADUs?

Like other Nebraska counties, Buffalo County does not publish a clear county-wide ADU policy online, but accessory dwelling units may be allowed under general accessory use provisions on existing lots. ADUs in Buffalo County must meet local zoning rules for accessory buildings, including setbacks from property lines  and compliance with building codes for permanent foundations and utility connections. Rental use typically aligns with local residential tenancy laws rather than county zoning. To determine specific regulations, reach out to the Buffalo County Zoning Office or the planning department of the city in which your lot is located, and ask for the accessory dwelling section of the county zoning code.

Does Dodge County Allow ADUs?

Possibly, but we can’t know for sure. Dodge County does not list a straightforward county-wide ADU policy online. Like most Nebraska counties, ADUs and tiny homes are regulated through local zoning districts and sometimes require a conditional use permit to approve a second dwelling on a single-family parcel. There is no published minimum ADU size or blanket allowance for all zones; properties in unincorporated areas must meet the county’s accessory use standards.  For accurate rules, contact the Dodge County Planning & Zoning Department at (402) 727-2724 or visit their zoning webpage to discuss your specific lot and zoning district.

Does Scotts Bluff County Allow ADUs?

Scotts Bluff County does not have clear, published ADU rules. Tiny homes and accessory dwellings may be allowed only through special zoning situations such as Planned Unit Developments (PUDs) or conditional use permits, depending on the district where your property is located. Homeowners must comply with accessory structure setbacks, relative size limits compared to the main house, and permanent utility connection requirements, but exact thresholds are decided at the county or municipal level. Contact the Scotts Bluff County Zoning Office or the planning department of the city where your parcel lies to confirm allowable uses. 

Does Madison County Allow ADUs?

Yes, it appears that way! Madison County does allow tiny homes on foundations, which are commonly treated as ADUs or secondary dwellings in many zoning districts, making it one of the more permissive Nebraska counties. For foundation-based ADUs, owners must follow building codes and local zoning rules for setbacks, lot coverage, and utility connections appropriate for residential accessory structures. Prospective ADU builders should contact the Madison County Zoning and Building Department to verify lot zoning classifications and any size or rental restrictions before starting the project.

Does Platte County Allow ADUs?

Platte County does allow tiny homes and accessory dwellings in many of its residential and rural residential zones, although the rules are not centrally published. ADUs must comply with all county-level zoning standards like lot size, building setbacks, height limits, and permanent utility hookups. Because precise size or rental limits are determined by district, contact the Platte County Zoning Office to understand what is permitted on your specific parcel. They can provide official size rules and any conditions tied to rental use or building permits. 

Does Lincoln County Allow ADUs? 

As of right now, online information about Lincoln County ADU policies is limited. Because ADU and tiny home regulations are set by individual county zoning districts or city jurisdictions in the county, there is no single published ADU standard for all of Lincoln County. Homeowners should reach out to the Lincoln County Zoning Department or, if inside an incorporated city within the county, that city’s planning office to determine whether ADUs are allowed, what setbacks are required, and whether any minimum size or rental restrictions apply. Confirming your zoning district is the essential first step for accurate, site-specific requirements.

Does Adams County Allow ADUs? 

Currently, Adams County does not publish a dedicated ADU ordinance. This means that ADUs may be permitted in residential or rural residential zones under general “accessory use” regulations if the structure is subordinate to the main residence and meets accessory building standards. Expect size caps relative to the main house, setbacks from property lines, and requirements for permanent utility connections. Before planning a build, contact the Adams County Planning & Zoning Department to confirm whether your property is inside an incorporated city or in the county, and to identify the applicable zoning district and rules. Their office can provide the most accurate setback and size requirements for your parcel. 

Does Cass County Allow ADUs? 

Maybe, but it is not definite. Cass County generally permits secondary dwellings in residential zones as long as they comply with accessory structure codes, but it does not define ADUs in a single, county-wide rule. Accessory units must remain smaller than the primary dwelling, respect lot coverage limits, and meet all other  requirements prescribed by the county or by the municipality if inside a city. Rental use is allowed under typical residential tenancy laws, but some conditional zoning districts may restrict long-term rentals. To confirm allowances and size thresholds, contact the Cass County Planning Office and request the accessory use section of the zoning regulations for your property’s zoning designation. 

Does Dawson County Allow ADUs? 

Dawson County may permit ADU-style units as accessory dwellings in certain residential or agricultural districts, but no widely published, county-wide ADU policy exists. Units must be clearly subordinate to the primary residence, follow size limitations (often capped to a fraction of the main home’s square footage), and meet county setback and building code requirements. Smaller, “tiny home”-style ADUs may be easier to allow if connected to permanent utilities and built on a foundation. If your property is within an incorporated community, the city zoning office will provide more precise rules, but in unincorporated areas contact the Dawson County Zoning Administrator to confirm allowable uses and any conditions or permits required.

Does Saunders County Allow ADUs? 

Yes! Saunders County does allow accessory dwellings under its accessory use provisions, with acceptance varying by zoning classification and whether you are in an unincorporated area or inside a municipality. ADUs must comply with accessory building size limitations, often staying under a set percentage relative to the main residence, and meet normal lot setbacks and height restrictions. Utility hookups to the primary home’s systems and compliance with residential building codes are also required. To get more specific details on your lot, contact the Saunders County Planning & Zoning Department; they can identify your zoning district and provide applicable code sections. 

Does Gage County Allow ADUs? 

Gage County does not have a one-size-fits-all ADU policy. The county allows secondary dwellings only where permitted by the zoning district, primarily under accessory building rules that restrict the unit’s size, location, and relationship to the primary dwelling. Expect standard accessory use requirements such as a certain square footage, standard setbacks, and utility connections. Detached ADUs may require a conditional use permit in some districts. To confirm if your lot can host an ADU and to get specific setback, maximum size, and rental-use rules, contact the Gage County Zoning Office; they will confirm your zoning district and applicable regulations.

Does Dakota County Allow ADUs? 

Yes, but not in all areas. Dakota County does allow accessory dwelling units in specific situations under its zoning regulations, but they are not universally permitted across all zones. Tiny homes or ADUs are recognized as accessory uses when they comply with the county’s accessory building rules, remain subordinate to the primary residence, and meet site-specific conditions like setbacks, size limits relative to the main house, and required utility hookups. Regulations vary by district, and detached units may require conditional approval in low-density areas. Prospective ADU builders should contact the Dakota County Joint Planning Commission or review the county’s zoning ordinance to confirm whether their parcel’s zoning district allows an ADU and what the specific requirements are.

Does Washington County Allow ADUs? 

Washington County does not have widely published, county-wide ADU guidelines, and the legality of ADUs there remains unclear without municipal or township clarification. Tiny home and accessory dwelling regulations vary by locality, and in many cases these units must meet general accessory structure requirements like meeting setback distances, having permanent utilities, and remaining subordinate in size to the primary home. To determine if an ADU is permitted for your specific parcel, contact the Washington County Zoning Office and request information on accessory uses in your zoning district. Their guidance will provide clarity on size limits, rental allowances, and whether conditional use approval is required. 

Does Seward County Allow ADUs? 

Seward County, like many Nebraska counties, does not issue a straightforward ADU policy on its public zoning pages, so the allowance of ADUs depends on local districts and municipal ordinances. Accessory dwellings may be allowed when they follow standard accessory building regulations which include size and setback guidelines.  Because regulations can vary significantly between unincorporated areas and incorporated cities within the county, contact the Seward County Zoning Administrator or the planning office of the specific city your property lies in to confirm. They will help you identify applicable lot area minimums, unit size limits, and any required permits.

Does Otoe County Allow ADUs? 

Yes! Otoe County does permit tiny homes and accessory dwellings on existing properties when they comply with the county’s accessory structure and building code requirements. Tiny home guidance suggests a county minimum of about 120 square feet and a 7-foot ceiling height for habitable ADUs, though that minimum is more commonly listed for tiny homes on foundations rather than ADU-specific zoning. ADUs must connect to permanent utilities, meet size rules subordinate to the main dwelling, and adhere to required setbacks and residential accessory standards. To confirm the exact setback distances, size allowances, and rental-use permissions for your parcel, reach out to the Otoe County Zoning Department or your local city’s planning office if inside an incorporated area.

Does Saline County Allow ADUs? 

Per many other Nebraska counties Saline County does not have clearly defined county-wide ADU regulations available online; general zoning rules usually dictate whether ADUs are allowed. If allowed, accessory units in Saline County must meet accessory building codes, including subordinate size relative to the primary house, compliance with setbacks and height requirements, and connection to permanent utilities. Detached ADUs or tiny homes may require special permits depending on the district, and rental usage will be governed by rental laws and local ordinance clarifications. It is best to contact your local departments, as the county does not govern it on a countywide basis. 

Does York County Allow ADUs?

It seems that way. York County zoning permits accessory uses broadly but does not treat ADUs as an automatic right under a single statewide code. Local regulations require any accessory dwelling to be subordinate to and on the same lot as a primary dwelling, though York’s older ordinance language lists accessory uses generally without explicit ADU size rules. For specifics like size limits, setbacks, rental use, or conditional-use requirements, contact the York County Zoning Administrator, as zoning varies by district. You can also review the county’s accessory use provisions in their zoning resolution or speak directly with their office for zoning clarification.

Does Box Butte County Allow ADUs? 

It isn’t known at this time, as Box Butte County does not provide public ADU-specific guidelines online, and accessory dwelling allowances depend on your parcel’s zoning classification. Typical county zoning covers accessory structures with rules for setbacks, lot coverage, and utilities, but does not confirm or deny ADUs by name. To find out if an ADU is allowed on your specific lot and to learn minimum size, rental rules, or if a conditional-use permit is required, contact the local zoning department in your area, and ask them how to proceed. 

Does Custer County Allow ADUs? 

It is very possible, but will need to be confirmed with the local government. Custer County permits accessory residential structures and innovative dwelling types like tiny homes or grain bin homes, provided they meet permanent foundation, utility hookup, and building code requirements. The county’s zoning resolution includes specific rules for accessory-type housing and short-term rental distinctions, so ADUs as subordinate dwellings are likely allowable if they comply with other requirements. Setbacks and specific use permissions vary by zoning district, so reach out to the Custer County Zoning Office or review the county’s 2022 zoning resolution to confirm how accessory dwellings are treated for your parcel.

Does Colfax County Allow ADUs? 

Colfax County allows tiny homes and accessory dwellings as long as they meet local building codes, including requirements such as a minimum 120 square feet of habitable space and proper egress, foundation, and utilities. Although the county doesn’t offer a single published ADU policy, accessory dwellings must follow typical accessory-use rules for setbacks, subordinate size, and residential zoning standards. To understand any size limits above this minimum, setback distances, or whether separate rentals are allowed, contact the Colfax County Building or Zoning Department for your property’s zoning district specifics.

Does Red Willow County Allow ADUs? 

Here again, Red Willow County’s zoning code does not explicitly list ADUs or tiny homes as permitted uses, and its 2012 zoning resolution categorizes accessory buildings generally. Because clear ADU guidelines are not available online, accessory dwellings are evaluated under typical accessory structure rules for setbacks, subordinate size to the main residence, and compliance with residential codes. The best next step is to contact the Red Willow County Planning & Zoning Office to determine if your lot’s zoning district allows a secondary dwelling and to request specific details on unit size, setback requirements, and rental permissions.

Does Holt County Allow ADUs? 

Holt County does not list a dedicated ADU category in its publicly available zoning materials. Accessory dwellings are typically considered accessory uses if they remain subordinate to a primary home and comply with general accessory building standards for setbacks, size relative to the main house, and utility connections. Detached ADUs may require conditional use approval in rural or agricultural zones. To determine whether ADUs are allowed on your property, contact the Holt County Zoning Office or the planning department of any incorporated city where the parcel is located.

Does Wayne County Allow ADUs? 

Following the pattern of many Nebraska counties, Wayne County does not offer a county-wide ADU ordinance; rather, accessory dwellings are regulated through zoning districts and municipal codes for properties inside city limits. This means that prospective ADU builders should contact the Wayne County Zoning Department or the City of Wayne Planning Office for details about allowed uses, conditional approvals, and permit requirements specific to their parcel.

Does Cheyenne County Allow ADUs? 

Cheyenne County treats secondary dwellings as accessory uses under its zoning ordinance and allows them on a case-by-case basis in residential and some rural residential zones. Units must follow the county’s accessory structure size limits, stay subordinate to the main dwelling, meet setback requirements, and connect to permanent utilities. Because local rules differ by zoning district, detached ADUs may require a special or conditional permit. Homeowners should contact the Cheyenne County Zoning Administrator to confirm if their lot allows an ADU, determine the specific setbacks and size caps, and inquire about rental use regulations.

Does Hamilton County Allow ADUs? 

Hamilton County does not provide a clear ADU section in its published zoning documents. Accessory units are regulated as accessory structures, and they must comply with the county’s lot coverage requirements, size limitations relative to the primary house, and standard setbacks from property lines. Utilities must be provided in compliance with building codes, and detached ADUs may require additional zoning review. To confirm whether ADUs are permitted for a specific parcel and to learn about minimum size, rental-use allowances, and conditional permits, contact the Hamilton County Zoning Office or check with the planning office of any city where your address resides.

Does Phelps County Allow ADUs? 

Phelps County considers accessory dwellings under its accessory use and building regulations but does not explicitly define an “ADU” category. Units must remain subordinate to the primary residence, meet all setback requirements, and comply with building codes for permanent foundations, plumbing, and electrical systems. Detached ADUs may need a conditional or special use permit depending on zoning classification. To confirm allowances, size limits, setback distances, and whether rentals are permitted on your parcel, contact the Phelps County Zoning Administrator or the municipal planning office if your property is inside an incorporated city.

Does Cuming County Allow ADUs? 

Cuming County allows accessory structures but does not have an explicit county-wide ADU definition. Secondary dwellings may be allowed if they meet accessory building criteria for lot coverage, setbacks, and subordinate size, and are equipped with permanent utilities. Detached ADUs may require conditional approval in more rural zoning districts. For specific regulations about minimum and maximum size, setback distances, and any rental restrictions, residents should contact the Cuming County Zoning Office or the planning department of the city where their parcel is located.

Does Butler County Allow ADUs? 

Unfortunately, Butler County lacks an explicit, county-wide ADU category and ADUs are generally treated as secondary or “accessory” uses in appropriate residential and rural residential districts. In some zoning districts, detached ADUs may require a special use permit. To get accurate, parcel-specific requirements, contact the Butler County Zoning Office or the planning department of the city where your property is located.

Does Knox County Allow ADUs? 

Knox County does not have a dedicated ADU ordinance; accessory dwellings are regulated under accessory use provisions in county and municipal zoning codes. Units must remain subordinate in size to the main home, meet accessory structure setbacks, and be built to residential building codes with permanent utilities. Rural or agricultural zoning districts may require conditional use approval for detached ADUs. Homeowners interested in building an ADU should contact the Knox County Zoning Office or, if located inside a city, that city’s planning department to confirm whether ADUs are allowed on their parcel, and to learn the  rules that apply.

Does Cedar County Allow ADUs? 

Cedar County, like most Nebraska counties, does not have a clearly defined “ADU” category in its zoning regulations. ADUs are treated as accessory residential uses under general zoning rules, which require them to remain subordinate to the main dwelling and to meet the county’s standard setbacks, lot coverage, and building codes. There are no widely published size or rental-use specifics in the publicly available Cedar County zoning documents. Homeowners interested in building an ADU in Cedar County should contact the Cedar County Planning & Zoning office for parcel-specific requirements, including setback distances and permitted accessory use conditions. Contact the office in Hartington or use the zoning resources on the county’s website.

Does Dawes County Allow ADUs? 

Information specifically outlining ADU regulations in Dawes County is not readily available online. Like most rural counties, accessory dwellings and tiny homes are generally evaluated as part of accessory structures within each zoning district. They must meet accessory building rules regarding setbacks from property lines, subordinate size relative to the main residence, and full compliance with building standards for permanent foundations and utilities. To determine whether an ADU is permitted for your property in Dawes County, you should contact the Dawes County Zoning Office directly for zoning designations, size limits, and any potential conditional-use requirements.

Does Keith County Allow ADUs? 

Keith County does not publish an ADU-specific ordinance. Accessory dwellings in the county typically fall under accessory use standards, with no separate ADU code. Homeowners planning a secondary unit must ensure that the proposed dwelling adheres to general accessory structure standards like subordinate square footage relative to the main house, setbacks, and required utilities. Because rules can vary by zoning district, you should reach out to the Keith County Planning & Zoning Department to identify your property’s zoning classification, potential size limits, and any restrictions on rental use or special permits.

Does Merrick County Allow ADUs? 

Merrick County does not provide clear ADU regulations online and treats accessory dwellings under its accessory-building codes. Accessory units are generally allowed if they remain secondary to the main dwelling, meet standard setbacks, and comply with residential building codes for utilities, foundations, and livability. If you plan to rent the unit or build a detached structure, you will likely face review under accessory use rules or possible conditional-use permits. For accurate zoning guidance, contact the Merrick County Zoning Office or the planning department of the city where your property is located to confirm allowable uses, size limitations, and setback requirements.

Does Richardson County Allow ADUs? 

Richardson County does not have a clearly defined ADU ordinance available online. Accessory dwellings are usually regulated through accessory use and accessory structure terms in its zoning resolution, requiring units to be subordinate to the primary residence and to meet setbacks, lot coverage, and building code rules. Detached units may require a conditional use permit in certain zoning districts. To confirm ADU allowances, size caps, and rental permissions in Richardson County, consult the Richardson County Planning & Zoning Department for your property’s zoning details.

Does Pierce County Allow ADUs? 

Pierce County does not list a standalone ADU policy online. Accessory dwelling units in Pierce County are handled through general accessory use regulations, meaning units must be subordinate in size to the main residence, compliant with local setbacks and lot coverage rules, and constructed to residential building codes. Rental usage is governed by local residential rental regulations and any homeowner-association rules if applicable. Prospective ADU builders should contact the Pierce County Zoning Office for parcel-specific zoning designations, which will determine whether a conditional use permit, size limits, or additional requirements apply.

Does Nemaha County Allow ADUs? 

It’s difficult to say as Nemaha County does not publish an explicit ADU ordinance. Accessory dwellings fall under accessory structure policies in the local zoning plan, so any ADU must meet size and setback standards for its zoning district and comply with full building codes for permanent occupancy. Depending on your parcel and zoning classification, detached units may need special or conditional permits. Contact the Nemaha County Planning & Zoning Department to identify exact zoning rules for accessory dwellings and learn about permitted use conditions for your specific address.

Does Jefferson County Allow ADUs? 

Currently, Jefferson County does not provide an ADU-specific code, and accessory dwellings are regulated under general accessory use and structure rules. Units are expected to remain secondary to the main residence in size and usage, adhere to setback requirements, and follow full residential building codes. Rental permissions may be handled by local city or township ordinances if inside a municipality. Homeowners in Jefferson County should contact the local Zoning Office or planning department for their specific parcel to verify zoning allowances, size limitations, and whether detached ADUs require additional approvals.

Does Kearney County Allow ADUs? 

At this time, Kearney County does not have a clearly published ADU ordinance at the county level, and accessory dwellings are treated as accessory structures under general zoning rules. Detached units or unusual designs may require conditional or special permits depending on the zoning district. Prospective builders should contact the Kearney County Zoning and Planning Department to verify whether their parcel’s zoning district allows an ADU and to get specifics on size limits, setbacks, and any permit requirements. Note that the City of Kearney itself has struggled with adopting ADU rules and currently does not move forward with ADU allowances in some city areas.

Does Burt County Allow ADUs? 

Burt County does not have a published ADU-specific section in its zoning code. Accessory units are typically treated as accessory buildings or secondary dwellings and must remain smaller than the primary residence, meet the county’s setback rules, and connect to utilities. Detached ADUs may require conditional or special approval in agricultural or low-density residential zones. To verify allowances for your site, contact the Burt County Zoning Office with your parcel details.

Does Thurston County Allow ADUs? 

Thurston County zoning does not explicitly define ADUs, but accessory dwellings are generally regulated as accessory uses that must be subordinate in size and scale to the primary home, follow setback rules, and comply with building codes. Because rural counties like Thurston handle ADUs case-by-case, the county planning department should confirm whether your parcel’s zoning district allows an accessory dwelling, what minimum and maximum size is required, and what permits are needed. Contact the Thurston County Zoning Administrator for parcel-specific clarification.

Does Howard County Allow ADUs? 

Howard County’s zoning code treats accessory dwellings under standard accessory use provisions. Any unit must meet customary setbacks, be subordinate to the primary dwelling in size, and connect to permanent utilities. Detached ADUs may require conditional use approval in rural areas. Contact the Howard County Zoning Office to determine your zoning district, confirm if your lot allows a secondary dwelling, and get exact setback distances and size criteria.

Does Antelope County Allow ADUs? 

Antelope County does not set a countywide minimum square footage for ADUs, and its publicly available zoning resolution does not explicitly define an “accessory dwelling unit.” Secondary units are allowed as accessory structures if they follow subordinate size guidelines, meet setback requirements, and comply with residential building codes. Detached units may require a conditional permit based on the parcel’s zoning classification. For specific requirements and restrictions, contact the Antelope County Zoning Office or the planning department of any incorporated city where your property sits.

Does Clay County Allow ADUs? 

Clay County’s zoning regulations do not identify ADUs by name, and any accessory living unit would be reviewed under the county’s general accessory building rules. Units must stay smaller than the main residence, meet applicable setbacks, and connect to permanent utilities. Size, rental-use permissions, and necessary permits depend on the local zoning district, so speak with the Clay County Zoning Administrator to confirm allowable uses, required distances from property lines, and any additional approvals for detached units.

Does Stanton County Allow ADUs? 

Stanton County does not have an ADU-specific definition, but accessory or secondary dwellings are often allowed if they comply with accessory use rules in each zoning district. ADUs must remain subordinate to the main dwelling in size, respect setbacks, and be built to residential code standards with permanent utilities. Detached units may require conditional use review depending on zoning. Reach out to the Stanton County Zoning Office to verify zoning allowances, setback standards, and permit requirements for your parcel.

Does Fillmore County Allow ADUs? 

Fillmore County treats ADUs as accessory dwellings under its ordinance, meaning these units can be permitted if they follow accessory use standards: they must be subordinate in size to the primary residence, meet setbacks, and adhere to building codes. Utility connections, access, and livability requirements (like egress and fire safety) must be satisfied. To determine whether your parcel’s zoning district allows ADUs and to get exact size and setback details, contact the Fillmore County Zoning Administrator.

Does Cherry County Allow ADUs? 

Cherry County deals with ADUs through accessory structure and accessory dwelling provisions. Units must remain auxiliary and subordinate to the main residence, follow lot coverage and setback rules, and be connected to permanent water, sewer, and electrical systems. Because zoning districts vary widely in rural counties, detached ADUs may require a conditional use permit or special approval in some areas. Contact the Cherry County Zoning Office to confirm whether your property’s zoning district allows a secondary dwelling and any specific size or usage limits.

Does Dixon County Allow ADUs? 

Dixon County does not have a specific ADU category in its publicly available zoning resources. Secondary units are regulated under accessory building standards, requiring a subordinate size, adherence to setback requirements, and compliance with building codes. Owner-occupancy or rental restrictions, if any, are dictated by township or municipal codes if the property is inside a city. Contact the Dixon County Planning & Zoning Office to confirm whether your parcel allows an ADU, what setbacks are required, and if any conditional permits are needed.

Does Boone County Allow ADUs? 

Boone County does not provide a clear ADU section in its zoning code, so accessory dwellings fall under the county’s accessory or secondary dwelling provisions. ADUs are permitted where the zoning district allows accessory residential uses, subject to size, height, and setback limitations relative to the main dwelling. Utility connections and building permits are required for habitable units. To confirm what is allowed on your property, contact the Boone County Zoning Office for your parcel’s zoning classification and applicable accessory use conditions.

Does Polk County Allow ADUs? 

Polk County zoning does not define “ADUs” explicitly; any accessory dwelling must comply with the county’s accessory structure rules. Units must be subordinate in size to the primary residence, meet required setbacks from property lines, and follow permanent utility requirements. Detached units in certain zoning districts may require conditional or special permit approval. Contact the Polk County Zoning Administrator or planning office for the parcel’s zoning details, size limits, and any rental restrictions.

Does Johnson County Allow ADUs? 

Johnson County’s zoning code does not list a specific “ADU” category, but it does include provisions for accessory dwellings in residential and rural residential districts. The county typically requires that any secondary dwelling stay subordinate to the main house, fit within permitted lot coverage, and meet setback and foundation requirements. Because the county values orderly development around its small towns, detached units often require a site plan and review if they are outside city limits. Your next step is to contact the Johnson County Zoning Administrator for your property’s zoning classification and ask about accessory dwelling allowances and any conditional permits needed.

Does Sheridan County Allow ADUs? 

Yes, but Sheridan County’s zoning ordinances handle additional living units under accessory use language rather than naming them ADUs. The county tends to be conservative with second dwellings in largely agricultural zones, often requiring conditional or special permits for detached dwellings. Units are expected to meet minimum habitable size standards of about 120 square feet for tiny dwellings but must also align with building codes if intended as long-term living space. Contact the Sheridan County Planning Office to understand setback requirements from roads and property boundaries, and to verify if your lot falls into a zone where accessory dwellings are permitted.

Does Thayer County Allow ADUs? 

Like the majority of Nebraska counties, Thayer County does not provide an ADU-specific section in its published zoning documents.Thayer has a fair amount of township-level autonomy, so rules can vary if your land is inside a particular township’s jurisdiction. Townships may impose minimum lot sizes or additional requirements for residential accessory buildings. Reach out to the Thayer County Zoning Office and, if inside a township, check with your township board for any additional permitting rules.

Does Furnas County Allow ADUs?

Furnas County handles ADUs through broad accessory structure regulations. Given the county’s mix of agricultural land and small towns, detached or stand-alone second dwellings often require a conditional use permit in agricultural districts. Furnas also has a history of requiring dwellings to connect to established water and sewer infrastructure in town limits, but outside towns, on-site wells and septic systems may require separate permitting. If you’re planning a detached unit, contact the Furnas County Zoning Administrator about soil evaluations for septic permits and the necessary setbacks from property lines and wells.

Does Morrill County Allow ADUs? 

Morrill County does not spell out ADUs in an explicit section; accessory dwellings fit into the county’s accessory use or small dwelling provisions. Morrill has historically prioritized spacing between structures in its rural towns, so accessory dwellings in urban-like areas may have tighter setback requirements (for example, 10–15 feet from side and rear lines) compared to agricultural areas. Water rights and placement of wells or septic systems are tightly regulated due to the county’s semi-arid environment. Before designing a unit, talk to the Morrill County Planning Office about setbacks tied to wells, property lines, and floodplain mapping, and confirm if a conditional use permit is needed.

Does Nuckolls County Allow ADUs? 

Nuckolls County zoning treats second dwellings as accessory structures in family and farm zones, with setbacks and size relationships to the primary residence as key considerations. Unlike more urban counties, Nuckolls has minimal regulations about owner-occupancy, but it enforces building codes for long-term occupancy and requires proper sanitation systems if you’re outside city sewer grids. Nuckolls County also tends to enforce minimum lot widths for additional dwellings in rural residential zones. For actionable details, contact the Nuckolls County Zoning Office and ask for their accessory building size, lot width minimums, and setback sheet for your zoning district.

Does Valley County Allow ADUs? 

Valley County, covering a range of rural towns and agricultural space, does not have a standalone ADU law. Accessory dwelling units are only permitted if they meet the county’s accessory use standards for their specific zoning district. Valley County will check your site for compliance with minimum lot size, placement of the dwelling relative to wells and septic systems, and required driveway access or culvert placement. The planning office also pays close attention to floodplain boundaries near the North Loup River — building in or near a floodplain may eliminate ADU options. To move forward, contact the Valley County Zoning Department, provide your address, and ask for the accessory dwelling rules for that zoning district, including minimum lot sizes and septic or well setback requirements.

Does Chase County Allow ADUs? 

Chase County’s zoning does not include a specific “ADU” category; instead secondary dwellings are evaluated under accessory-use rules. Accessory units are permitted in residential and some rural residential zones if they remain subordinate in size to the primary home, adhere to lot coverage limits, and meet setback requirements. Chase County often ties accessory dwelling approvals to the parcel’s classification and its proximity to water and sewer infrastructure, with stricter standards inside towns like Imperial. For confirmed details about size restrictions, required setbacks from property lines, and whether a detached unit needs a conditional permit, contact the local zoning department in your area. 

Does Webster County Allow ADUs? 

Webster County treats additional dwellings as accessory structures unless located inside a town with its own ordinances. Units must meet setback requirements, usually similar to those for garages and barns, and be connected to permanent utilities if intended for long-term occupancy. Because the county’s zoning is largely rural, detached dwellings often require a conditional use review in agricultural zones rather than being permitted by right. Speak with the Webster County Planning & Zoning Office to confirm your zoning district’s allowances and any minimum lot size or occupancy restrictions.

Does Kimball County Allow ADUs? 

Kimball County addresses accessory dwellings under its general accessory building section, without a specific ADU policy. Units must stay subordinate to the main residence in size and appearance, and they must comply with setbacks, height limits, and necessary utility hookups for permanent occupancy. Detached units in agricultural zones typically require special or conditional permits due to spacing and water-access concerns. To confirm allowable sizes, required setbacks, and any required permit process for your parcel, reach out to the Kimball County Zoning Office.

Does Nance County Allow ADUs? 

Nance County does not define ADUs explicitly but allows accessory uses that include a smaller secondary dwelling on a parcel, subject to accessory-structure size limits, property setbacks, and full compliance with state building codes. Nance County has historically focused more on accessory garage and workshop standards, so a unit intended for living will require a detailed review of water, septic, and egress compliance. Some towns within Nance County handle ADUs differently, so if your lot is inside a municipality, check with both the county and the city’s planning department. Contact the Nance County Zoning Office to identify your zoning district and request specific size and setback criteria.

Does Harlan County Allow ADUs? 

As of right now, Harlan County does not provide a clear ADU section in its zoning documents; secondary dwellings are regulated under accessory building and accessory-use codes. Units must be subordinate to the main home, follow the county’s setback rules, and connect to permanent utilities for occupancy. Harlan County is known for requiring a full building permit review for any living unit outside city sewer systems, meaning septic approval and well placement will be checked early. Detached units in agricultural zones generally require conditional or special approval. For exact size caps, setback distances, and potential permit or conditional-use requirements, contact the Harlan County Zoning Administrator for your parcel.

Does Sherman County Allow ADUs? 

Sherman County does not offer clear, publicly-published ADU or tiny-home guidelines. Like most Nebraska counties without explicit ADU sections, any second dwelling or tiny-home-style unit must comply with general accessory-structure rules (subordinate size, setbacks, and full building code compliance for utilities). For up-to-date regulations and specific requirements for your parcel, contact the Sherman County Planning & Zoning Office in Loup City.

Does Brown County Allow ADUs? 

Brown County does not have a well-documented, county-wide ADU policy online, and tiny home guidance notes that clear information is scarce. Accessory dwellings are governed by local zoning provisions controlling accessory structures, setbacks, and utility standards. To determine whether your property allows an ADU and what size, setback, or permit requirements apply, reach out to the Brown County Planning & Zoning Office. 

Does Franklin County Allow ADUs? 

Franklin County does not publish specific ADU rules, so accessory dwellings are typically regulated under general accessory or secondary-dwelling ordinances, if at all. Prospective ADUs usually have to meet subordinate size requirements, building code standards, and setback rules for non-agricultural zoning districts. Contact the Franklin County Planning & Zoning Office to confirm whether an ADU is allowed on your parcel and what the local size or conditional-use requirements are. 

Does Perkins County Allow ADUs? 

Information about ADUs in Perkins County is not specifically documented online, and tiny home references are unclear. Accessory dwellings would usually need to qualify as subordinate structures under the county’s zoning district regulations, comply with setbacks, and meet building-code requirements if intended for habitation. Because rules vary by zoning classification, contact the Perkins County Planning & Zoning Department for parcel-specific answers about setbacks, size caps, shared utilities, and whether detached units require special permits.

Does Frontier County Allow ADUs? 

Frontier County has limited public documentation on ADUs or tiny homes, and unofficial resources list counties with a 900-square-foot minimum for dwellings in some areas, potentially influencing ADU feasibility. For accurate guidance and to verify any minimum size limits or conditional-use requirements, contact the Frontier County zoning office directly. They can confirm whether the county treats ADUs as allowed accessory uses or restricts smaller dwellings under residential-minimum requirements.

Does Hitchcock County Allow ADUs? 

Hitchcock County’s tiny-home and ADU regulations are not easily found online, suggesting that ADUs fall under broad accessory-structure rules. Any dwelling unit intended for long-term occupancy must meet local setbacks, subordinate size requirements, and state building codes for utilities and egress. Contact the Hitchcock County zoning or planning department to identify your parcel’s zoning classification, permitted accessory uses, and any applicable minimum-size or occupancy requirements.

Does Pawnee County Allow ADUs? 

Pawnee County does not publish explicit ADU rules or tiny-home guidance, and local zoning is the final authority. Accessory dwellings usually must remain subordinate to the main residence, meet setback rules, and connect to utilities. Rental or occupancy limits vary by township or municipal jurisdiction if the parcel is inside a city. Contact the Pawnee County Planning & Zoning Office with your address or parcel number to confirm whether an ADU is permitted, what setbacks apply, and whether detached units need additional approvals.

Does Greeley County Allow ADUs? 

Greeley County doesn’t list a dedicated ADU regulation online, and some Nebraska guides note the county enforces a 900-square-foot minimum for new dwellings, making tiny houses or small ADUs unlikely unless very specific exceptions apply. If you’re considering an ADU, contact the Greeley County Zoning Office to confirm whether accessory dwellings are permitted under their current zoning code, and ask if any minimum-square-foot requirements apply. The Nebraska Legislature defines ADUs as dwellings accessory to a single-family home on the same lot, but enforcement and details are local.

Does Deuel County Allow ADUs? 

There is very little information publicly available about Deuel County’s stance on ADUs or tiny homes. Like most counties without explicit ADU ordinances, secondary dwellings would be evaluated as accessory structures subject to general zoning rules for setbacks, size relative to the main house, and utility requirements. Your best next step is to contact the Deuel County planning or zoning department for parcel-specific requirements and whether any minimum dwelling size or conditional permits are needed. 

Does Gosper County Allow ADUs? 

Gosper County does not publish clear ADU or tiny-home regulations, and zoning documents accessible online do not directly mention accessory dwellings. Prospective ADUs in the county would be regulated through accessory or secondary-dwelling provisions of the zoning code, which require units to remain secondary to the main home and comply with standard setbacks, height, and utility rules. To confirm allowances and any minimum size requirements, contact the Gosper County Zoning Office with your parcel’s address and legal description.

Does Garden County Allow ADUs? 

Garden County’s zoning code does not offer a clear public stance on ADUs or tiny homes, and tiny-home guides for Nebraska place it among counties with “limited information.” Accessory dwellings, if allowed, will likely require compliance with accessory-structure rules, including setbacks, subordinate size limits, and full residential building code requirements. Before planning, contact the Garden County Planning or Zoning Department to confirm whether ADUs are permitted in your area and what conditions apply. 

Does Garfield County Allow ADUs? 

Garfield County has a documented zoning code where certain uses — including conditional uses under agricultural and rural residential districts — may apply, but it does not spell out ADUs by name. Accessory dwellings are usually possible if permitted as a conditional use, and units must meet accessory building standards for setbacks, structure size compared to the main residence, and permanent utilities. Reach out to the Garfield County Zoning Office to understand whether an ADU could be approved as a conditional use on your property. 

Does Boyd County Allow ADUs? 

Boyd County does not provide easily accessible ADU or tiny-home laws online, and most Nebraska rural counties without published guidelines treat ADUs as accessory or secondary dwellings subject to general zoning standards. In Boyd County, any accessory unit will need to follow setback, building code, and subordinate-size rules. To learn whether your parcel allows an ADU and what minimum dwelling size or additional permits might be required, contact the Boyd County Zoning Department.

Does Dundy County Allow ADUs? 

Dundy County doesn’t have published ADU or tiny-home guidelines, and zoning information online is minimal. If ADUs are permitted, they will be treated under general accessory-use rules that demand compliance with local setbacks, subordinate scale to the main house, and full utilities for a habitable dwelling. Contact the Dundy County Planning or Zoning Office to confirm whether accessory dwellings are allowed for your parcel, and what minimum size or permit requirements apply under the county’s zoning code.

Does Rock County Allow ADUs? 

As of this time, Rock County does not publish clear ADU or tiny-home rules online and is among the rural Nebraska counties where zoning details are not widely documented. Given the absence of explicit guidance, secondary dwellings are likely treated under general “accessory structure” or “secondary dwelling” rules that require units to remain subordinate to a primary home and comply with setbacks and building code standards. Because Rock County has a small population and largely agricultural zoning, detached ADUs could require conditional or special approval in non-urban zones. The best next step is to contact the Rock County Zoning Department in Bassett to confirm if ADUs are permitted on your parcel, and what setbacks and permits would be needed.

Does Sioux County Allow ADUs? 

Sioux County does not provide specific public guidelines on tiny homes or ADUs, making it unclear whether they are permitted as secondary dwellings. In counties like Sioux, zoning codes generally treat secondary units as accessory structures, with approval dependent on the parcel’s zoning classification and utility access. For definitive information, contact the Sioux County Planning or Zoning Office with your property address to learn if ADUs are allowed, and what setbacks, minimum size rules, or conditional permits might be required. Like many rural Nebraska counties, the zoning office is your most reliable resource. 

Does Hayes County Allow ADUs? 

Hayes County does not have obvious published rules for ADUs or tiny homes, so any accessory dwelling would be subject to the county’s accessory-use and building-code requirements. Most Nebraska counties without tiny-home-specific language still allow accessory units in residential zones if they meet setbacks, subordinate size limits, and utility requirements. Because Hayes County zoning is mainly agricultural with few urban centers, detached units are often reviewed case-by-case or require conditional permits. Contact the Hayes County zoning or planning office for exact conditions, including minimum structure size and whether rentals are allowed. 

Does Keya Paha County Allow ADUs? 

Keya Paha County’s tiny-home or ADU rules are not clearly documented online. Like many less-populated Nebraska counties, it relies on broad accessory-structure definitions that require a secondary unit to be subordinate to the main dwelling, meet setbacks from property lines, and satisfy building-code requirements for habitability. If your property is inside a small town, city ordinances may override county rules and could be stricter or more detailed. To determine allowances, reach out to the Keya Paha County zoning office or the planning department of the town where your parcel is located. 

Does Wheeler County Allow ADUs? 

It is not possible to know for sure as Wheeler County does not clearly outline ADU policies online, though resources list it among counties with sparse public guidance on tiny homes. Without explicit county ADU rules, secondary units must be evaluated under accessory-use and zoning standards that focus on setbacks, size compared to the main house, and permanent utilities. Contact the Wheeler County Zoning Administrator to get specifics for your zoning district. They can highlight where on your land an ADU might fit and whether any conditional use permits would be required.

Does Hooker County Allow ADUs? 

Hooker County offers little to no information online about tiny homes or ADUs, and the lack of public policy suggests accessory dwellings fall under standard zoning language. Any ADU would have to stay subordinate in size to the primary residence, meet required setbacks, and comply with building and utility codes. Hooker County’s Planning or Zoning Office is the only route to accurate parcel-specific details. Call or email them with your address to confirm whether ADUs are allowed and what minimum size, setback, and permit requirements are in place.

Does Thomas County Allow ADUs? 

Unfortunately, Thomas County does not publish ADU-specific rules, and information online is scarce. In Nebraska, tiny homes and ADUs are governed by local jurisdictions’ accessory-use codes, which means Thomas County likely treats them as accessory structures that must be subordinate, meet setbacks, and comply with building codes. Because zoning policies vary widely, reaching out to the Thomas County Zoning Department is essential. They can confirm whether the zoning designation of your parcel allows an ADU, any minimum or maximum unit size, and what permits or conditions apply.

Does Banner County Allow ADUs? 

Banner County is one of the rural, sparsely documented counties where tiny-home and ADU rules are not clearly spelled out online. It is generally treated like other rural Nebraska counties, if accessory dwellings are permitted at all, they would be regulated under general accessory-structure rules, requiring subordinate size, adherence to setbacks, and full utility hookups for permanent occupancy. To verify whether your parcel can host an ADU and any required permits, reach out to the Banner County zoning or planning office.

Does Logan County Allow ADUs? 

Logan County’s tiny-home or ADU stance isn’t clearly documented in statewide tiny-home guides. Like many counties in Nebraska’s Region 3, ADUs are typically treated as accessory dwellings under general zoning rules, with approval dependent on your parcel’s zoning classification and lot conditions. Contact the Logan County Zoning Department to confirm whether accessory dwellings are permitted on your property and what rules apply, including setbacks, minimum size limits, and any conditional-use requirement.

Does Loup County Allow ADUs? 

Loup County does not appear on lists of counties that explicitly “allow” tiny homes or ADUs, and clear guidance is scarce. As with other rural counties, an ADU would be evaluated under accessory-use provisions in the local zoning code, which typically require the structure to remain secondary in size and location to the primary dwelling and to meet setbacks and building-code requirements. For a definitive answer, contact the Loup County Planning & Zoning Office about the zoning designation for your parcel and any accessory-dwelling standards. 

Does Grant County Allow ADUs? 

Grant County is included in Nebraska’s Region 3 planning designation alongside other sparsely populated counties such as Hooker and Arthur. Tiny-home resources do not list Grant as one of the counties with published ADU or tiny-home friendliness. In practice, any accessory dwelling would need to comply with general accessory-structure standards about subordinate size, setbacks, and connections to utilities. To learn whether they will approve an ADU on your property, contact the Grant County zoning or planning department for parcel-specific guidance.

Does Blaine County Allow ADUs?

Blaine County is grouped with counties such as Loup, Greeley, and Sherman in statewide planning documents but is not listed among counties with known clear tiny-home or ADU rules. If allowed, accessory dwellings would fall under the county’s accessory use or secondary dwelling definitions and require conformity with size, setback, and utilities requirements. For accurate, site-specific expectations, including whether the county enforces any minimum dwelling size, contact the Blaine County Zoning Office directly.

Does Arthur County Allow ADUs? 

Arthur County is one of Nebraska’s least populated counties and, like similar rural counties, has not published a clear ADU or tiny-home policy. Because land-use decisions are handled locally, any accessory dwelling would need to meet the county’s accessory structure and building code requirements, such as staying smaller than the main residence, following standard setbacks, and connecting to permanent utilities. Contact the Arthur County Planning or Zoning Department for parcel-specific rules and whether a conditional or special permit is required for an ADU. 

Does McPherson County Allow ADUs? 

McPherson County is also part of Nebraska’s Region 3 planning area and is not listed among counties with widely documented ADU-friendly policies. Like many rural counties, ADUs are evaluated under generic accessory use provisions, including subordinate size, proper setbacks, and compliance with building codes and utility connections. Due to the county’s limited online zoning information, the most reliable method is to contact the McPherson County zoning office or county clerk’s office to verify whether an ADU is permitted on your lot and what the minimum requirements are.

Does Omaha, Nebraska, Allow ADUs? 

Yes! Omaha is much more progressive when it comes in ADUs in Nebraska. Accessory dwelling units are permitted, under a by right law, without the need for a special permit. ADUs in Omaha can be attached, internal, or detached from the primary dwelling. Currently, there is no maximum size limit on the ADU and it does not require additional parking space. Additionally, it can be rented out either short or long term. The Omaha government offers a helpful page on ADU information for interested homeowners looking for more guidance on the process. 

Does Lincoln, Nebraska, Allow ADUs? 

It sure does! ADUs are encouraged as a strategic housing solution in Lincoln. However, there are specific regulations governing them. Any ADUs must not exceed 800 square feet, or 40% of the primary house. It is limited to one bedroom and usually requires owner occupancy on the property. For more information on how to take the next steps, reach out to the Lincoln Zoning Department. 

Does Bellevue, Nebraska, Allow ADUs? 

Bellevue generally allows accessory dwelling units, but they aren’t labeled as “ADUs” in the zoning code. Instead, homeowners can build “guest quarters,” which function like ADUs but must remain subordinate to the primary home and comply with residential zoning standards. Detached units may require additional review, and the city often expects ADUs to match the character of the main structure, follow standard setbacks, and meet building code requirements for plumbing, electrical, and foundations. Before planning a project, contact Bellevue’s Planning Department, which can confirm whether your lot qualifies and what approvals you’ll need. 

Does Grand Island, Nebraska, Allow ADUs? 

Yes, Grand Island does allow accessory dwelling units in many residential districts, typically as a permitted accessory use on single-family lots. ADUs must stay under the maximum accessory structure size limits, meet all rear-yard setback requirements, and cannot exceed the height restrictions set for the zoning district. While Grand Island is relatively friendly toward ADUs, projects usually require a building permit and sometimes an additional zoning review to confirm compliance with parking and occupancy standards. Homeowners should review the zoning code and contact the Building Department to verify requirements. 

Does Kearney, Nebraska, Allow ADUs? 

No, Kearny does not allow ADUS. While there has been some discussion around whether that can be changed, as of right now, homeowners are not allowed to build ADUs. For more information, you can contact your local building or zoning department to see if an exception can be made or a special use permit be obtained. 

Does Fremont, Nebraska, Allow ADUs? 

Yes! According to the city’s zoning ordinances, Fremont allows ADUs by right, meaning you won’t need to apply for a special use or conditional permit to own one. The maximum size of ADUs in Fremont are 850 square feet or up to 75% of the primary dwelling, whichever is smaller. Additionally, the design of the ADU needs to match a similar style of the primary dwelling unit. Reach out to the Fremont Zoning and Planning Department for guidance on the next steps. 

Does Norfolk, Nebraska, Allow ADUs?  

It sure does. Norfolk is one of the more ADU-friendly Nebraska cities, allowing secondary dwellings on single-family lots and adopting building standards that support small homes and efficient construction. The city follows the 2018 International Residential Code, including Appendix Q for small dwellings, which makes it easier to build compact ADUs with loft spaces and reduced ceiling heights. ADUs must sit on permanent foundations, meet setback and parking requirements, and remain smaller than the primary residence. Homeowners can confirm zoning district rules and required permits by contacting Norfolk’s Planning & Zoning Division.

Does Hastings, Nebraska, Allow ADUs? 

It is possible, but not crystal clear. Hastings permits accessory living quarters in residential zones, though it excludes the tiny-home Appendix Q from its adopted codes, meaning ADUs must meet full residential building standards. Units must comply with accessory structure size limits, match neighborhood character, and follow setback and height regulations established in the zoning ordinance. Detached ADUs may require zoning review or conditional use approval depending on the district, and homeowners should expect a full building-permit evaluation for utilities and structural compliance. For the latest requirements and zoning interpretation, contact the Hastings Planning Department.

Does Columbus, Nebraska, Allow ADUs? 

Yes! Columbus allows accessory dwelling units in residential areas, treating them similarly to other permanent accessory structures. ADUs must comply with the city’s maximum accessory structure size limitations, follow standard setbacks, and remain smaller than the primary home. Columbus also requires all accessory dwellings to be built on permanent foundations and to meet full residential building code standards, including utilities, egress, and life-safety requirements. Because zoning codes can vary depending on your specific zone, homeowners should contact the Columbus Building Department to confirm the zoning rules that apply to their property:

Does Papillion, Nebraska, Allow ADUs? 

Yes, but it can be difficult to obtain. Papillion permits accessory dwelling units only under its accessory use provisions, and some residential districts require conditional approval before a detached ADU can be built. The city limits accessory structures by size and height relative to the primary dwelling and enforces typical setbacks for side and rear yards. Papillion and Sarpy County closely coordinate zoning, so homeowners should verify whether their lot falls under city or county jurisdiction, as that affects which ADU rules apply. For zoning maps, applications, and permit guidance, visit Papillion’s Planning Department

Does North Platte, Nebraska, Allow ADUs? 

Yes, but only with strict regulations. North Platte allows accessory living quarters but has historically enforced minimum dwelling-size requirements that can make very small ADUs difficult without seeking variances. ADUs must comply with accessory structure standards, meet setback and height rules for the district, and be clearly secondary to the main house. Detached units may require additional review to ensure they don’t exceed size and lot-coverage limits, and full building permits are required for utilities and structural work. To confirm what’s currently allowed on your specific parcel, contact the North Platte Building Department. 

Does La Vista, Nebraska, Allow ADUs? 

It is unclear at this point. La Vista does not publish detailed ADU-specific language in its zoning code, but it does allow certain forms of secondary living quarters under accessory use regulations. Any ADU-like structure must comply with accessory building size limits, remain subordinate to the primary home, and meet all residential setbacks and lot-coverage rules. Because the city doesn’t formally define ADUs, homeowners should expect case-by-case review and may need conditional approval for detached units or structures with kitchens. For zoning confirmation and permit steps, contact La Vista’s Community Development Department. 

Does Scottsbluff, Nebraska, Allow ADUs? 

It sure does! Scottsbluff permits small secondary dwellings and is relatively open to compact living units, provided they meet the city’s minimum size requirements, typically between 200 and 750 square feet for habitable accessory structures. ADUs must follow standard setbacks, cannot exceed height limits for accessory buildings, and must be built on permanent foundations with full compliance to residential building codes. Detached ADUs may require a zoning review or conditional use permit depending on the neighborhood, and parking requirements may apply. Homeowners should verify their zoning district and ADU allowance with the Scottsbluff Building & Zoning Office

Does South Sioux City, Nebraska, Allow ADUs? 

It is possible, although not explicitly stated at this time. South Sioux City does not clearly outline ADUs in its zoning code, but secondary living quarters may be permitted as accessory uses in certain single-family districts. Units must comply with accessory structure size limits, meet setbacks, and remain clearly subordinate to the main house. Because ADUs are not explicitly labeled in the code, homeowners should be prepared for conditional-use review, especially for detached units with full kitchens or separate entrances. To confirm what’s allowed for your specific parcel, contact the South Sioux City Planning Department

Does Beatrice, Nebraska, Allow ADUs?  

Like some other Nebraska municipalities, Beatrice allows certain forms of secondary living quarters, though the zoning code does not provide a dedicated “ADU” category and handles them under accessory structures or accessory residential uses. Any ADU-like dwelling must comply with the city’s accessory building standards, including size limits, height restrictions, and setbacks from property lines. While this does not provide direct confirmation for ADU allowance, it gives you some leeway to work with. Homeowners should connect directly with the Beatrice Building & Zoning Department to confirm current allowances and permit procedures for their specific lot.
