Welcome to the lovely state of North Dakota, where wide-open landscapes abound with communities where land is still relatively accessible compared to much of the country. From the energy-driven growth of the west to the steady expansion of cities like Fargo and Bismarck, the state has seen gradual population shifts that are quietly reshaping housing needs. Many North Dakota homeowners have more space on their lots than those in dense metro areas, and properties often include room to expand. That combination makes the idea of adding an accessory dwelling unit especially appealing as North Dakota families look for flexible ways to use the space they already own.
Accessory dwelling units are small housing spaces that provide completely independent living for aging parents or friends and family who need extra space. Since North Dakota leaves most ADU decisions up to local communities, many homeowners are discovering that these small homes can be a smart and realistic option once they understand local zoning and permitting. Zook Cabins is here to provide a guide to ADUs in North Dakota, providing you with all the essential information you need to succeed.
Are ADUs Allowed in North Dakota?
Yes, although as stated earlier, there is no state regulation of ADUs, so local counties and municipalities determine their own regulations. North Dakota is not necessarily considered an ADU-friendly state, although that may change in the next several years as they gain popularity. For now, ADU allowance is limited to only a few municipalities, with the remaining counties and municipalities unclear. However, we also suggest going directly to your local zoning department and asking them what is allowed. They may be able to help you with zoning variance, conditional use permits, or other avenues which allow an ADU on your property that aren’t listed online.
What is Considered An ADU in North Dakota?
North Dakota follows a standard definition for ADUs, defining them as small, independent living spaces with fully functional sanitation, sleeping, and cooking facilities. Larger cities in North Dakota allow different types of ADUs, from detached units, to attached or conversion types.
Can Park Model Tiny Homes Be Used As ADUs?
It depends. Park model homes are built to all the standards of a fully certified RV, making them technically mobile. Gernallery, accessory dwelling units are meant to be on a permanent foundation. However, some counties do allow park model homes to be used as an ADU. For the best clarity, get the plans in hand, and head to the building department to review codes and allowances with the planning staff.
And if you don’t like what your municipality has to say about tiny homes, see what other states have to say about their use in the table below:

Can Log Cabins Be Used As An ADU?
Yes! A log cabin can be used as an ADU in North Dakota, but only if it meets local zoning and building code requirements. The ADU structure must be considered a permanent, habitable dwelling with proper insulation, utilities, and foundation. In areas that allow ADUs, a log cabin is simply another construction style, it still needs to follow rules for size, setbacks, and occupancy. If your local zoning doesn’t allow ADUs, the style of the structure won’t change that, making log cabins ineligible.
Can Modern Cabins Be Used As An ADU?
Definitely. Modern cabins are often one of the most practical ADU options because they’re designed for efficient living and easier permitting. As long as the structure meets residential building codes and local zoning allows a second dwelling, a modern cabin can function as an ADU. Make sure to choose a model that stays within the size limits and you should be good to go.
What is the Difference Between a Prefab ADU & a Modular ADU?
A prefab ADU is a broad term that refers to any home built off-site and then delivered to the property. A modular ADU is a specific type of prefab that is constructed in sections in a factory and assembled on a permanent foundation. Modular homes must meet the same building codes as site-built homes, while some prefab options (like tiny homes on wheels) may not qualify as legal ADUs in many areas. In North Dakota, if you want something recognized as an ADU, modular builds are typically the safer route.
What is the Minimum Size for an Accessory Dwelling Unit?
Minimum size requirements vary by city, but many places follow general building code standards that require enough space for living, sleeping, cooking, and sanitation. In areas that do define ADUs, you’ll often see minimums around 300–400 square feet, but this is not consistent statewide. Always verify with your local zoning office.
Can My ADU be Bigger Than My House?
In the majority of cases, no. Where ADUs are allowed, they are required to be smaller than the primary residence. Some cities cap ADUs at a percentage of the main home’s size or set a fixed maximum square footage. If your area doesn’t clearly define ADUs, this will likely be determined during the approval process.
How Close To My House Can I Build An ADU?
This depends on local setback and separation rules. Some areas allow attached ADUs within the home, while detached ADUs usually need to sit a certain distance from the main house and property lines. For example, some jurisdictions require around 10 feet of separation from the primary home and a few feet from side and rear lot lines, but exact requirements vary and must be confirmed locally.
Do You Need A Permit For An ADU in North Dakota?
Yes. If an ADU is allowed on your property, you will need permits. This typically includes zoning approval (which may be a conditional or special use permit) and building permits to ensure the structure meets residential codes. In North Dakota, this process is handled at the local level, so requirements will vary depending on your city or county. You can also expect to need electrical, plumbing, and HVAC permits, although again, these will vary by your specific area.
Are There Any Incentives or Grants for ADUs in North Dakota?
There are no widely available statewide incentives or grant programs specifically for ADUs in North Dakota. Most homeowners fund ADU projects privately. Occasionally, local housing programs or rural development initiatives may offer assistance, but these are not ADU-specific and can vary widely. However, it’s always worth checking with local housing authorities or economic development offices for any current opportunities that you would qualify for.

In many cases, our standards even exceed the building codes. This ensures you have a safe, high-quality ADU that will pass all inspections and last for generations.
Can an ADU Have Multiple Bedrooms and Bathrooms?
Yes, if local zoning laws allow, it is common for ADUs to have one or two bedrooms, and sometimes even more than one bathroom. The extra bedroom space offers more living space for a small family or an extra guest room. Browse our models to see which ADU fits your specific needs.
Are ADUs A Good Investment?
The quick answer is, yes, ADUs are often an excellent investment due to their versatility and relatively low upfront cost. Plus, they add property value and have the potential for rental income. These factors combined make ADUs a smart choice the majority of the time. That said, local limitations can influence how practical they may be for your financial situation. It is always wise to think carefully through the process, and contact experienced teams to discuss your options.

Does Cass County, ND, Allow ADUs?
Unfortunately, we can’t say one way or the other, due to limited available information. Cass County does not clearly outline specific rules for accessory dwelling units at the county level, and most zoning decisions are handled within individual cities like Fargo or West Fargo. This means ADUs may be allowed, restricted, or require a conditional use permit depending on the exact municipality and zoning district.
If you’re a homeowner in Cass County, your best move is to check directly with your city’s planning or zoning department, since county-wide guidance on ADUs is not clearly defined and local ordinances will control what’s possible.
Does Burleigh County, ND, Allow ADUs?
Burleigh County itself does not provide clear, publicly defined ADU rules at the county level, but the city of Bismarck within the county does allow ADUs under specific conditions such as size limits, owner occupancy, and special use approval. Outside of city limits, ADU regulations are less clearly stated and may depend on rural zoning classifications or case-by-case approval.
Homeowners should contact either Burleigh County Planning and Zoning or the City of Bismarck Planning Department to confirm what is allowed on their specific property.
Does Grand Forks County, ND, Allow ADUs?
It is unclear at this point. Grand Forks County does not clearly publish county-wide ADU regulations, and zoning is often handled at the city level. Within the City of Grand Forks, ADUs are not widely supported based on past policy direction, meaning they may be restricted or not currently permitted in typical residential zones.
If you are considering an ADU in this area, you will need to verify directly with local planning officials, as the rules are not clearly defined at the county level and may vary significantly depending on location.
Does Ward County, ND, Allow ADUs?
Ward County, which includes Minot, does not have clearly published county-wide ADU standards, but ADUs can be approved within the City of Minot through a conditional use process. This means ADUs are not automatically permitted but are very likely though a specific approval process. Homeowners can expect a review process rather than a simple permit and should contact Minot Planning or Ward County officials for exact guidelines.
Does Williams County, ND, Allow ADUs?
Williams County does not clearly define ADUs in its zoning ordinances, but it regulates land use through a formal planning and zoning process where additional residential dwellings may require a conditional use permit and review. In practical terms, this means ADUs are not explicitly guaranteed but could be possible depending on zoning district and approval.
If you are an interested ADU homeowner, you can connect directly with the Williams County Planning and Zoning Division to determine feasibility, as all projects must comply with zoning regulations and go through permitting before construction.
Does Morton County, ND, Allow ADUs?
It is very likely. Morton County does appear to allow accessory dwelling units, but not by default. County materials indicate that ADUs may be permitted in certain zoning districts like Agricultural and Residential, typically requiring a special or conditional use approval rather than being automatically allowed.
Homeowners should expect a review process and should confirm details like lot size, placement, and utilities with the Morton County Planning and Zoning Department before moving forward, since the rules are not presented in a simple, homeowner-friendly format online.
Does Stark County, ND, Allow ADUs?
Yes! Stark County is one of the clearer counties in North Dakota when it comes to ADUs. The zoning ordinance explicitly defines and allows accessory dwelling units, but they require a conditional use permit and must meet strict requirements. These include minimum lot size (typically around 60,000 square feet), owner occupancy, size limits (generally capped at 80 percent of the main home or 1,500 sq ft), placement in side or rear yards, and additional parking.
Bottom line? ADUs are allowed, but they are regulated closely, so homeowners should review the Stark County zoning code or contact planning staff before starting.
Does Stutsman County, ND, Allow ADUs?
Like the majority of North Dakota, Stutsman County does not clearly identify accessory dwelling units in an easy-to-find or clearly defined way within its zoning ordinance, and most of the language focuses on general land use and agricultural zoning. This means ADUs may not be explicitly addressed or may fall under broader residential or accessory use categories.
Homeowners should not assume they are allowed and should contact the Stutsman County Zoning Administrator directly to determine if a second dwelling unit is permitted on their specific property.
Does Richland County, ND, Allow ADUs?
Richland County does not clearly outline rules specific to accessory dwelling units in its publicly available zoning materials, and references are primarily tied to general accessory structures rather than separate living units. Because of this, it is not clear whether ADUs are formally permitted, restricted, or handled on a case-by-case basis.
If you are interested in building an ADU, you should reach out to the county planning office or their township to clarify what is allowed before making any plans.
Does McKenzie County, ND, Allow ADUs?
McKenzie County regulates land use through a comprehensive Land Development Ordinance, but publicly available information does not clearly state whether accessory dwelling units are specifically allowed. This suggests ADUs may not be explicitly defined and could require interpretation under existing zoning rules or a conditional use process.
Homeowners should work directly with McKenzie County Planning and Zoning to determine feasibility, as approval will depend heavily on zoning district and compliance with broader development standards.
Does Rolette County, ND, Allow ADUs?
Rolette County does not have publicly accessible or clearly defined zoning regulations that address accessory dwelling units, and available information suggests zoning decisions are largely handled at the local municipal level rather than county-wide.
For homeowners, this means ADUs are not clearly permitted or prohibited at the county level, and you will need to contact your specific town or city zoning office to determine what is allowed on your property before moving forward.
Does Ramsey County, ND, Allow ADUs?
Following the pattern of other North Dakota counties, Ramsey County does not clearly define rules for ADUs in its zoning materials, and even proposed ordinances do not provide specific guidance on small secondary dwellings. This lack of clarity means ADUs may not be formally addressed and could depend on interpretation or local city regulations, so homeowners should reach out directly to the Ramsey County Planning and Zoning Department or their local municipality to confirm what is allowed.
Does Barnes County, ND, Allow ADUs?
It is likely. Barnes County does allow certain smaller dwelling types like park model homes (typically under 400 square feet) in specific zoning districts, which can sometimes overlap with ADU-style living arrangements. However, ADUs as a clearly defined use are not explicitly outlined, so while smaller secondary units may be possible in the right zoning district, homeowners should verify with Barnes County Planning and Zoning to understand placement, permitting, and whether a true ADU is allowed.
Does Walsh County, ND, Allow ADUs?
It is very possible. Walsh County appears to allow small dwelling units in some form, as long as they meet building regulations and may require a conditional use permit depending on the zoning district. That said, ADUs are not clearly defined in a straightforward way, so homeowners should expect a review process rather than automatic approval and should contact the county auditor or zoning officials to confirm requirements before planning a project.
Does McLean County, ND, Allow ADUs?
McLean County allows smaller residential structures such as park model homes under certain conditions, including minimum size requirements (around 256 square feet) and compliance with building codes. However, ADUs are not clearly labeled or defined in an easy-to-understand way, so while a secondary dwelling may be possible, homeowners should contact McLean County Planning and Zoning to confirm whether an ADU is permitted on their specific property and what approvals would be required.
Does Mountrail County, ND, Allow ADUs?
It appears so! Mountrail County is one of the few counties that actually defines something very close to an ADU in its land development code, describing an “accessory residential dwelling” as a smaller independent unit on the same lot as a primary home. However, the county does not clearly present simple, homeowner-friendly rules on how these are allowed, and zoning authority may also vary by township.
In practice, this means ADUs are possible, but you will likely need to go through zoning review or a conditional use process. Homeowners should contact Mountrail County Planning and Zoning directly to confirm what is allowed on their specific property. The staff there can also answer questions about size and setback limits.
Does Mercer County, ND, Allow ADUs?
Historically, Mercer County’s zoning ordinance has focused heavily on traditional residential uses and agricultural land, with accessory uses required to remain clearly secondary to the main dwelling, but it does not clearly outline ADUs as a defined or permitted use. This makes it unclear whether a separate living unit would be approved without special review.
For homeowners, that means ADUs are not guaranteed and may require interpretation, zoning approval, or a conditional use permit. You should contact Mercer County Planning and Zoning before making any plans to understand feasibility.
Does Traill County, ND, Allow ADUs?
It is unclear. Traill County does not provide publicly accessible or clearly defined zoning regulations that address ADUs, and available information suggests these decisions are often handled at the city or township level rather than county-wide. Because of this, it is not clear whether ADUs are allowed, restricted, or reviewed case-by-case. Homeowners should reach out directly to their local municipality or zoning office within Traill County to determine what is possible on their specific property.
Does Pembina County, ND, Allow ADUs?
While Pembina County’s zoning ordinance allows primary dwellings and accessory buildings, it does not clearly define or list ADUs as a permitted use. This creates a gray area where a second living unit may not be automatically allowed and could require special approval or may not be permitted depending on interpretation. Homeowners should contact Pembina County Planning and Zoning to clarify whether a second habitable unit can be added to their property.
Does Bottineau County, ND, Allow ADUs?
Bottineau County does not clearly publish county-wide ADU regulations, and available zoning information is limited, with much of the guidance focused at the city level rather than the county. For example, the City of Bottineau outlines zoning districts and requires permits for construction but does not clearly address ADUs as a defined use. This means ADUs are not clearly permitted at the county level, and homeowners should contact their local city or township zoning office to determine what is allowed before moving forward.
Does Benson County, ND, Allow ADUs?
Following a similar pattern of most North Dakota counties, Benson County does not clearly define accessory dwelling units in its zoning regulations, and available information suggests there are no specific guidelines addressing them at the county level. For homeowners, this means ADUs are not explicitly permitted or prohibited, and approval would likely depend on how local officials interpret existing zoning rules.
Your best move is to contact the Benson County zoning office or your local municipality to confirm whether a second dwelling is allowed on your property before making plans.
Does Ransom County, ND, Allow ADUs?
Unfortunately, Ransom County does not appear to specifically address ADUs in its zoning regulations, leaving a lack of clear direction for homeowners. In practical terms, this means ADUs are not guaranteed and may require special approval or may not be allowed depending on your zoning district. Homeowners should reach out to their local city or county zoning office to determine what is permitted and what type of approval process may be required.
Does McHenry County, ND, Allow ADUs?
As of right now, McHenry County does not provide clear, publicly available guidance on accessory dwelling units, and ADUs are not specifically outlined in an easy-to-find way within its zoning materials. Because of this, it is not clear whether ADUs are allowed outright or would need to go through a conditional or case-by-case approval process. Your next best step is to contact the county planning office or their local municipality to verify feasibility before moving forward.
Does Dickey County, ND, Allow ADUs?
Due to limited information, it’s hard to know for sure. Dickey County does not publicly share detailed zoning regulations related to ADUs, and available information indicates that land use decisions are often handled at the municipal level. If you’re considering building one, you will need to contact your local city or township zoning authority to determine what is allowed on your specific property.
Does LaMoure County, ND, Allow ADUs?
Like its other North Dakota county neighbors, LaMoure County does not clearly outline ADU-specific regulations at the county level, and while zoning processes exist (including permits and approvals through local commissions), there is no clear mention of accessory dwelling units as a defined use. For homeowners, this means ADUs are not clearly permitted and may require interpretation or special approval. You should contact LaMoure County or your local city zoning office directly to understand what is possible before starting any plans.
Does Dunn County, ND, Allow ADUs?
Dunn County does not clearly define ADUs in its zoning language, but available guidance does say that smaller secondary dwellings like park model units may be treated as temporary or recreational uses unless placed on a permanent foundation. For homeowners, this means a true ADU is not clearly permitted by default and may require interpretation or special approval.
You should contact Dunn County Planning and Zoning directly to confirm whether a permanent second dwelling is allowed on your property before moving forward. Bring the plans with you and be prepared to answer the different questions they may have for you.
Does Pierce County, ND, Allow ADUs?
Because Pierce County does not make its zoning regulations easily accessible online, there is no clear indication that ADUs are defined or permitted at the county level. This lack of clarity means ADUs are not guaranteed and may depend on local town or city rules rather than county-wide standards. Homeowners should reach out to their local municipality or the county zoning office to determine what is allowed on their specific property.
Does Wells County, ND, Allow ADUs?
Wells County does not currently include clear guidelines for accessory dwelling units in its zoning regulations. Because ADUs are not specifically addressed, it is not clear whether they are permitted or restricted, and approval may depend on how local officials interpret existing rules. Homeowners should contact Wells County Planning and Zoning or their local city office to get a clear answer before starting any plans.
Does Sargent County, ND, Allow ADUs?
At this time, Sargent County does not publicly share detailed zoning regulations related to ADUs, and zoning decisions are likely handled at the municipal level rather than through a clear county-wide policy. This means it is not clear whether ADUs are allowed, and homeowners should not assume they are permitted. The best step is to contact your local city or township zoning office for guidance specific to your property.
Does Sioux County, ND, Allow ADUs?
Sioux County does not provide publicly available zoning information that clearly addresses accessory dwelling units, and land use decisions are typically managed at the local municipality level. As a result, it is not clear whether ADUs are allowed or how they would be regulated. Homeowners should contact local zoning authorities or tribal/local jurisdiction offices to determine what is permitted before planning an ADU project.
Does Cavalier County, ND, Allow ADUs?
Like most North Dakota counties, Cavalier County does not clearly publish zoning regulations that define or address accessory dwelling units, and there is no straightforward guidance available indicating whether they are permitted. This means ADUs are not clearly allowed or prohibited at the county level. For homeowners, the best path forward is to contact Cavalier County officials or your local municipality to determine if a second dwelling unit can be approved under existing zoning rules.
Does Foster County, ND, Allow ADUs?
It’s not clear at this time. Foster County does not provide clear, publicly accessible information that outlines rules for accessory dwelling units. ADUs are not specifically defined in an easy-to-find way, which leaves uncertainty around whether they are permitted.
Homeowners should not assume they are allowed and should instead reach out to Foster County or their local city zoning office to confirm what is possible on their property.
Does Emmons County, ND, Allow ADUs?
Currently, Emmons County does not clearly define ADUs in its zoning materials, and there is no readily available guidance showing that they are a permitted use. Because of this, it is unclear whether a secondary dwelling would be approved or how it would be classified.
We recommend that homeowners connect directly with Emmons County planning or zoning officials directly to determine whether an ADU is allowed and what approvals would be required.
Does Nelson County, ND, Allow ADUs?
Unfortunately, Nelson County does not appear to have clear, publicly available rules specifically addressing accessory dwelling units. Zoning information is limited, and ADUs are not clearly listed as a permitted use. For homeowners, this means ADUs are not guaranteed and may depend on local interpretation or municipal rules.
You can contact the county or your local township or city to verify what is allowed before planning a project.
Does Bowman County, ND, Allow ADUs?
Bowman County allows smaller residential structures such as tiny homes in certain districts, provided they meet building code requirements and are placed on a permanent foundation. However, ADUs are not clearly defined as a separate use in an obvious, homeowner-friendly way, so it is not guaranteed that a second dwelling unit would be automatically approved.
Homeowners should contact Bowman County Planning and Zoning to confirm whether an ADU is permitted on their specific property and what requirements would apply.
Does McIntosh County, ND, Allow ADUs?
McIntosh County does not clearly define ADUs in publicly available zoning information, and there is no straightforward guidance indicating whether a second independent dwelling is permitted. This lack of clarity means ADUs are not explicitly allowed or prohibited at the county level.
For homeowners, the safest approach is to contact McIntosh County officials or your local township to determine if a secondary dwelling can be approved under current zoning rules before moving forward.
Does Hettinger County, ND, Allow ADUs?
Right now, Hettinger County does not provide clear, accessible zoning language that specifically addresses ADUs, and there is no obvious indication that they are a permitted use. Because of this, it is not clear whether an ADU would be allowed or how it would be regulated.
Homeowners should reach out directly to Hettinger County or their local municipality to confirm whether a second dwelling unit is possible on their property.
Does Kidder County, ND, Allow ADUs?
Kidder County does not clearly outline ADU regulations in an easy-to-find or homeowner-friendly format, and accessory dwelling units are not specifically defined in available materials. This creates uncertainty around whether they are permitted or would require special approval.
If you’re considering building an ADU, you should contact Kidder County Planning and Zoning or your local township to understand what is allowed in your specific zoning district.
Does Renville County, ND, Allow ADUs?
Renville County does not clearly define accessory dwelling units in its zoning regulations, and there is no straightforward guidance indicating they are permitted by default. Because ADUs are not specifically addressed, approval may depend on interpretation or a conditional use process.
Homeowners should contact Renville County planning officials to confirm feasibility, zoning requirements, and any approval steps before starting a project.
Does Eddy County, ND, Allow ADUs?
Eddy County does not clearly publish ADU-specific regulations, and available zoning information does not clearly state whether secondary dwelling units are allowed. This means ADUs are not guaranteed and may require case-by-case approval or may not be permitted depending on local interpretation.
Contact the Eddy County Zoning Department or your local city zoning office to determine what is possible on your property. They may have more information available in person than what is online in writing.
Does Griggs County, ND, Allow ADUs?
Griggs County zoning is often handled at the township level, and while some township regulations exist, they do not clearly define or standardize rules for accessory dwelling units. This means ADU allowances can vary significantly depending on where your property is located within the county.
Since ADUs are not explicitly permitted or prohibited, the key step is to contact your township or county officials directly to determine whether a second dwelling unit is allowed and what requirements would apply.
Does Grant County, ND, Allow ADUs?
Grant County does not clearly define accessory dwelling units in publicly available zoning materials, and there is no straightforward indication that a second independent dwelling is permitted by default. This means ADUs are not explicitly allowed or prohibited at the county level.
For interested homeowners, approval would likely depend on how local officials interpret existing zoning rules, so the best step is to contact Grant County or your local township to confirm whether a second dwelling unit is allowed on your property.
Does Adams County, ND, Allow ADUs?
Currently, Adams County does not provide clear, accessible zoning language that specifically addresses ADUs, and there is no obvious indication that they are a permitted use. Because of this, it is not clear whether an ADU would be allowed or how it would be regulated.
Homeowners could reach out directly to their local municipality to determine if a second dwelling can be approved under current zoning rules. This direct connection may help you more in the long run!
Does Divide County, ND, Allow ADUs?
Divide County does not clearly outline accessory dwelling units in its zoning regulations, and available information suggests there are no specific ADU guidelines in place. This lack of clarity means ADUs are not guaranteed and may require case-by-case approval or may not be permitted depending on zoning interpretation.
Homeowners should contact Divide County Planning and Zoning directly to understand what is allowed before moving forward.
Does Burke County, ND, Allow ADUs?
As of the time of our research, Burke County does not clearly define ADUs in its publicly available zoning materials, and there is no clear indication that they are permitted as a standard use. This creates uncertainty for homeowners, as a second dwelling unit may require special approval or may not be allowed at all depending on the zoning district.
The safest approach is to contact Burke County or your local city zoning office to verify what is possible on your specific property.
Does Towner County, ND, Allow ADUs?
Towner County does not have clear, publicly available zoning information that specifically addresses accessory dwelling units, and there is no straightforward guidance indicating whether they are allowed. Because of this, ADUs are not clearly permitted at the county level.
Homeowners should reach out to Towner County officials or their local municipality to determine if a second dwelling unit can be approved under current zoning rules.
Does Oliver County, ND, Allow ADUs?
Oliver County’s zoning ordinance allows for conditional uses and gives the Planning and Zoning Commission authority to approve uses that are not explicitly listed, but it does not clearly define or list ADUs as a permitted use. This doesn’t mean ADUs are explicitly prohibited, but you may need to pursue a conditional use permit or zoning variance to have them allowed.
To find out more about ADU feasibility, zoning requirements, and what approval steps would be required before starting a project, you can reach out to your local zoning department.
Does Logan County, ND, Allow ADUs?
Logan County does not clearly define accessory dwelling units in publicly available zoning materials, and available information provides little detail on how secondary dwellings are regulated. For homeowners, this means ADUs are not explicitly permitted or prohibited, and approval would likely depend on local interpretation or township-level decisions.
You should contact Logan County or your local municipality to confirm whether a second dwelling unit is allowed on your specific property.
Does Steele County, ND, Allow ADUs?
Steele County does not make its zoning regulations easily accessible online, and there is no clear indication that ADUs are defined or permitted at the county level. This lack of transparency means ADUs are not guaranteed and may be handled at the city or township level instead.
Call or email the Steele County Zoning Department and they might be able to provide information that is not available in writing.
Does Golden Valley County, ND, Allow ADUs?
It is not clear at this time. Golden Valley County’s zoning ordinance provides very limited detail regarding smaller or secondary dwellings, and ADUs are not clearly defined as a permitted use. Because of this, it is not clear whether an ADU would be allowed or how it would be reviewed.
Homeowners can contact Golden Valley County or their local municipality to understand what approvals may be required and whether a second dwelling is possible.
Does Sheridan County, ND, Allow ADUs?
Sheridan County does allow smaller residential structures under certain conditions, such as homes as small as around 256 square feet if they meet building code requirements and are placed on a permanent foundation. However, ADUs are not clearly labeled or defined as a separate use, so a second dwelling unit may still require approval or interpretation.
Homeowners should contact local zoning authorities to confirm whether an ADU is permitted on their specific property.
Does Billings County, ND, Allow ADUs?
Billings County has a formal zoning ordinance and requires building and zoning approval for any new structure or change in use, but it does not clearly define ADUs as a standard permitted use. This means a second dwelling unit would likely require review and approval rather than being automatically allowed.
If you are interested in moving ahead, you can work with the Billings County Planning and Zoning Department to determine feasibility, zoning compliance, and required permits.
Does Slope County, ND, Allow ADUs?
Slope County does not make its zoning regulations publicly accessible, and there is no clear information indicating whether ADUs are allowed. This means ADUs are not clearly permitted at the county level and may be handled by individual municipalities instead.
Homeowners should always contact local zoning officials directly to determine what is allowed on their property before moving forward.
Accessory Dwelling Unit Requirements by Municipality
Does Fargo, North Dakota, Allow ADUs?
Fargo does not clearly list ADUs as a simple, by-right use in an easy-to-find way in its zoning code, and everything runs through its Land Development Code, which strictly controls land use and building approvals. In practice, this means a second dwelling unit is not automatically allowed on most residential lots and may be restricted depending on the zoning district. You will need to verify your exact zoning and likely go through a formal approval or variance process if allowed at all. Your next best step is to contact Fargo Planning & Development or review the Land Development Code to confirm whether your property can support a second dwelling before doing anything else.
Does Bismarck, North Dakota, Allow ADUs?
Yes! Bismarck is one of the clearest and most ADU-friendly cities in North Dakota. ADUs are allowed, but they require approval and must follow strict guidelines. Expect limits like one ADU per lot, size caps (no larger than 800 sq ft unless on larger lots), and requirements that the owner lives on-site. Detached units must meet setback and height rules, and you’ll need one additional parking space. Rentals are typically allowed long-term, but short-term use may be restricted depending on zoning. Contact Bismarck Planning & Zoning and apply for a special use permit as this is not a simple over-the-counter approval.
Does Grand Forks, North Dakota, Allow ADUs?
Unfortunately, it doesn’t appear so. Grand Forks has historically not supported ADUs in standard residential zoning, and there is no clear, widely available ordinance showing they are permitted. This means ADUs are likely restricted or not allowed in most situations. However you can always reach out to the Grand Forks Planning & Community Development directly and ask if any zoning districts or exceptions allow ADUs. They may be able to help you with a zoning variance or conditional use permit.
Does Minot, North Dakota, Allow ADUs?
Yes, Minot does allow ADUs in some cases, but not by default. They are typically handled through a conditional use or approval process, meaning you’ll need to submit plans and get reviewed. Expect requirements around lot size, parking, and ensuring the unit remains secondary to the main home. Design and size limits will depend on zoning, and approval is not guaranteed. Rentals may be allowed depending on how the permit is structured. Before moving ahead, you’ll want to contact the Minot Planning Department and ask about conditional use approval for an accessory dwelling before investing in plans.
Does West Fargo, North Dakota, Allow ADUs?
Like most of North Dakota, West Fargo does not clearly define ADUs in a straightforward way, and most available guidance focuses on accessory structures like garages, not separate living units. This is a red flag that a second dwelling is not automatically permitted. Some forms of small housing may be allowed depending on zoning, but ADUs as a defined use are unclear. Next step: contact West Fargo Planning & Zoning directly and ask specifically about “accessory dwelling units” or “secondary dwelling units” for your zoning district.
Does Williston, North Dakota, Allow ADUs?
While Williston has zoning and land development controls in place, ADUs are not clearly defined as a standard permitted use in easily accessible materials. This suggests that a second dwelling unit would likely require approval or may not be allowed depending on zoning. In energy-driven areas like Williston, housing regulations can be stricter or tied to specific districts. Next step is to contact Williston Planning & Zoning and confirm whether your property allows more than one dwelling unit before moving forward.
Does Dickinson, North Dakota, Allow ADUs?
Following the same pattern of most North Dakota cities, Dickinson does not clearly publish straightforward ADU regulations in an easy-to-find format, and accessory dwelling units are not widely defined as a standard permitted use in publicly available materials. This means ADUs are not guaranteed and may require interpretation or a conditional approval depending on zoning. You should expect restrictions around size, placement, and utilities if they are allowed, but nothing is clearly standardized. The planning and zoning department can also help answer your questions, as they may have more information that is not available online.
Does Mandan, North Dakota, Allow ADUs?
Mandan does not clearly present ADUs as a simple, by-right use, but given its proximity to Bismarck and similar zoning structure, a second dwelling is very possible through a conditional use or special approval process. There is no clear, homeowner-friendly guideline outlining size limits, rental rules, or design standards, which means everything will depend on zoning and review. Contact the Mandan Planning Department and ask whether your property can support a second dwelling unit and what approval path is required.
Does Jamestown, North Dakota, Allow ADUs?
It’s not clear at this time. Jamestown does not clearly define ADUs in its zoning code in a way that makes them obviously permitted. This typically means a second dwelling unit is either restricted or handled through a case-by-case approval process. You should not assume rental use or detached units are allowed without review. Reach out to Jamestown Planning and Zoning to confirm whether an ADU is allowed in your zoning district and whether a conditional use permit is required.
Does Wahpeton, North Dakota, Allow ADUs?
Wahpeton does not clearly outline ADUs as a defined use in publicly available zoning information. This creates a gray area where a second dwelling unit may not be permitted by default and could require special approval or may not be allowed at all depending on zoning. Wahpeton City Hall or Planning & Zoning is the best place to go to for more information.
Does Devils Lake, North Dakota, Allow ADUs?
Yes! Devils Lake is one of the few smaller cities with actual documentation referencing ADUs. The city has published guidance which says ADUs must meet full residential building codes, connect to utilities (or prove adequate private systems), and comply with zoning regulations. Size, placement, and design will still depend on zoning district rules. Rentals may be possible but are not clearly defined in the summary. Review Chapter 17 zoning code and contact Devils Lake Building Department to confirm exact requirements for your lot.
Does Valley City, North Dakota, Allow ADUs?
Valley City does not clearly define accessory dwelling units in publicly accessible zoning materials, and there is no straightforward indication that a second independent dwelling is permitted by default. This usually means ADUs are either restricted or handled on a case-by-case basis depending on zoning. You should not assume you can build one, and rental use or detached units are especially uncertain. For the most clarity, you can contact the Valley City Planning Department and ask the staff there about the possibility of an ADU.
Does Watford City, North Dakota, Allow ADUs?
Watford City does not clearly outline ADUs as a defined or permitted use in easily accessible zoning information. Given the area’s rapid growth and stricter development controls tied to oil activity, additional dwelling units may be regulated more tightly than in rural areas. The lack on online information does not necessarily mean ADUs are outlawed, it may just be a harder process. Work with the Watford City Zoning Department to see if you can pursue other paths of approval for your ADU.
Does Horace, North Dakota, Allow ADUs?
Horace, being a fast-growing suburb near Fargo, follows structured zoning regulations but does not clearly present ADUs as a simple, by-right option in publicly available materials. This typically means secondary dwelling units are limited or require approval, and you should expect restrictions around size, placement, and design if they are allowed at all. Next step: contact Horace Planning & Zoning and ask directly about “accessory dwelling units” or “secondary dwellings” in your zoning district.
Does Lincoln, North Dakota, Allow ADUs?
Lincoln is one of the few smaller cities in North Dakota actively discussing ADUs, with recent conversations around expanding rules to allow them more broadly. This suggests ADUs may be allowed or becoming more accessible, but rules are still evolving and not fully standardized. Expect requirements around size, placement, and utilities, along with a formal approval process. Next step: contact Lincoln City Hall or Planning & Zoning to get the most current ADU rules and confirm whether your property qualifies under the latest updates.
Does Grafton, North Dakota, Allow ADUs?
Grafton does not clearly define ADUs in publicly available zoning information, and there is no obvious indication that they are permitted as a standard residential use. This creates a gray area where a second dwelling may require special approval or may not be allowed depending on zoning. Guidelines around size, design, and rental use are not clearly stated. Before proceeding with more plans, connect with your local housing authority to see what they have to say about ADU allowance options.
Does Beulah, North Dakota, Allow ADUs?
Even though Beulah has a full zoning ordinance and permitting process in place, it does not clearly define or list ADUs as a standard permitted use in an obvious, homeowner-friendly way. This means a second dwelling is not automatically allowed and would likely require interpretation, a conditional use, or direct approval from the city. Contact Beulah City Hall or Planning & Zoning and ask directly whether your property can have more than one dwelling unit before moving forward.
Does New Town, North Dakota, Allow ADUs?
New Town does not clearly publish accessible zoning information that defines ADUs as a permitted use, and land use regulations can be influenced by both city governance and tribal jurisdiction. This creates a gray area where ADUs are not guaranteed and may be restricted or require special approval depending on the property. Contact the local planning authority and confirm whether a second dwelling unit is allowed on your lot before making plans.
Does Casselton, North Dakota, Allow ADUs?
Unfortunately, Casselton does not clearly define ADUs in publicly available zoning materials, and like many smaller cities near Fargo, it follows structured zoning without clearly allowing secondary dwellings by default. This means ADUs are likely not permitted outright and may require special approval if considered at all. However, you can always reach out to the Planning Department and ask what they recommend.
Does Rugby, North Dakota, Allow ADUs?
Rugby does not clearly outline ADUs as a defined or permitted use in accessible zoning documents. This typically means a second dwelling unit is not automatically allowed and may be restricted or handled case-by-case depending on zoning. There are no clearly published rules around size, design, or whether rentals are allowed. Next step: contact Rugby City Hall or the local zoning office to confirm whether your property can support an additional dwelling unit and what approvals would be required.
Does Hazen, North Dakota, Allow ADUs?
Hazen has zoning and permitting requirements in place, but it does not clearly define ADUs as a standard permitted use in publicly accessible materials. This means a second independent dwelling is not automatically allowed and would likely require interpretation or approval from the city. Hazen City Hall can help direct you towards other options like a zoning variance or conditional use permit.
Does Stanley, North Dakota, Allow ADUs?
Just like its fellow cities, Stanley does not clearly outline ADUs in its publicly available zoning information, and there is no straightforward indication that they are permitted by default. In areas with rapid growth like Stanley, housing regulations can be more controlled, which often limits additional dwelling units unless specifically approved. Because of this, ADUs are not guaranteed and may require special approval or may not be allowed depending on zoning. Next step: contact Stanley City Hall or Planning & Zoning to confirm whether a second dwelling is allowed on your property.
Does Lisbon, North Dakota, Allow ADUs?
Lisbon does not clearly define accessory dwelling units in accessible zoning documents, and there is no clear indication that they are a permitted use in residential zones. This typically means ADUs are either restricted or handled on a case-by-case basis. There are no clearly outlined rules for size, placement, or rental use. Don’t give up yet though, you can always contact City Hall to see what they have to say about ADUs.
Does Bottineau, North Dakota, Allow ADUs?
While Bottineau has zoning districts and requires permits for construction, it does not clearly define ADUs as a standard permitted use in a simple, easy-to-find format. This creates a gray area where a second dwelling may require special approval or may not be allowed, depending on zoning. There are no clearly published guidelines for ADU size, design, or rental use.
We recommend you contact Bottineau City Hall or Planning & Zoning to determine whether a second dwelling unit is allowed on your property and what requirements would apply.
