ADU Regulations in New Mexico: The Complete Guide

ADU Regulations for New Mexico
The Grove ADU

With picturesque, arid deserts, cliffs, and vast canyons, New Mexico offers a breathtaking rugged beauty for its residents. The only thing better is enjoying it all from the comfort of a modular ADU, or more commonly known in New Mexico as a casita. These beautiful permanent tiny homes are perfect for rental opportunities, hosting friends and family, or housing aging parents. When it comes to owning an accessory dwelling unit, the first step is understanding the legalities and regulations around it. That’s why Zook Cabins is here to explain the details, break it down by counties and cities, and prepare you for success. Ready to learn? Let’s dive right in.

Are ADUs Allowed in New Mexico?

The Rivara ADU

The short answer is yes, ADUs are allowed in New Mexico. That allowance comes with a few caveats though. It is important to note that New Mexico does not have any statewide standards when it comes to casitas. This does not mean they aren’t allowed, it simply means they are governed at a county and municipality level, making each area different. We suggest forming a close partnership with your local building and zoning departments, as this is critical to a smooth ADU journey.

What Is Considered An ADU in New Mexico?

Most cities in New Mexico define an ADU as an independent housing unit that is smaller than a primary dwelling unit, while still retaining its own facilities for cooking, sleeping, living, and sanitation. There are various types of ADUs, the most popular being detached modular ADUs. You can also have an internal conversion ADU, where you would convert an attic or garage into its own living space. Or you could add an addition onto the house, for an attached-style accessory unit. Whichever model you choose, it will provide additional private space for your needs.

Can Park Model Tiny Homes Be Used As ADUs?

The Outpost

Tiny homes are usually considered mobile, and our park model homes fall into this category, being built to all the standards of a certified RV. However, some places allow park model homes to be parked permanently as an ADU. For the best clarification, call your local zoning department and explain what you would like to do with the park model home.

Can Log Cabins Be Used As An ADU?

The Lariat Log Cabin

Yes! Log cabins can be a perfect alternative to the traditional casita, although depending on your design laws for ADUs, it may not fit the traditional aesthetic. However, if it is allowed, choose a smaller model to fit within the size range and you are good to go!

Can Modern Cabins Be Used As An ADU?

If you need a more modern look to complement your current dwelling, cozy modern cabins are perfect. They are both functional and fashionable, which is ideal for an ADU. Confirm with your zoning department that this is a viable option for an ADU in your area, but as long as the size fits within the required limit, you should be ready to take the next step.

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

The A-Frame Dwelling

The only primary difference is the crafting and assembling. Modular ADUs are crafted in sections, then delivered and assembled on site, which allows for precise adjustments. Prefab ADUs are more of a “kit” with the ADU being crafted almost entirely off site then delivered and installed. When it comes to regulations, New Mexico does not differentiate between the two types.

What is the Minimum Size for an Accessory Dwelling Unit?

New Mexico does not set a statewide minimum ADU size because requirements are handled by local cities and counties. To get an exact minimum size, the next step is to ask your city or county planning department for their local zoning and building code requirements. However, you can expect in the range of 200-400 square feet as a minimum.

Can My ADU be Bigger Than My House?

Almost never. In New Mexico cities that regulate casitas, the ADU must remain clearly secondary to the primary home. Many cities cap ADUs around 750–1,000 square feet or limit them to a percentage of the main home’s size. The goal is to keep the casita as an accessory residence, not a second primary home. Check your local zoning office to confirm the size limits that apply to your property.

How Close To My House Can I Build An ADU?

Setbacks are controlled locally, not statewide. The distance from the main home and property lines depends on zoning, lot size, and whether the ADU is attached or detached. Detached casitas typically must follow rear and side yard setback rules similar to other accessory buildings, and they usually cannot be placed directly on the property line. For example, Albuquerque requires a 5 ft rear and side setback. Your planning department can provide the exact setback requirements for your zoning district.

Do You Need A Permit For An ADU in New Mexico?

Yes. In every part of New Mexico, a permit is required to build a casita. Even in rural counties without clear ADU ordinances, a second dwelling must go through zoning review, building permits, and inspections. You will typically need zoning approval, building permits, and utility/septic approval. The first step is always to contact your local planning or building department before designing or building.

Are There Any Incentives or Grants for ADUs in New Mexico?

Unfortunately, there is no statewide ADU grant or incentive program currently available. Some cities may occasionally offer housing or affordable housing programs that could apply to ADUs, but these are not consistent across the state and change over time. If incentives exist, they are usually tied to affordable housing programs run by local governments or housing authorities. The best place to check is your city housing department or local housing authority.

What Features are Included in An ADU from Zook Cabins?

Each ADU delivered and installed by Zook Cabins is built for quality and functionality. Each ADU boasts a modern design with all the comforts of a full-sized home. No matter which model you choose, you’ll be set up with a kitchen, bathroom, and bedroom (s) that are designed for maximum space efficiency and aesthetic appeal.

Are Zook Cabin’s ADUs Built to Code?

Definitely! Each of the units are built to match and exceed your local building permits.  Zook Cabins provides all the construction details, engineering, and documentation that local building departments typically require during the permitting process. However, you as the property owner are still responsible for obtaining permits and confirming that the ADU meets local zoning rules for size, placement, and use.

Can an ADU Have Multiple Bedrooms and Bathrooms?

They sure can. New Mexico does not limit the number of bedrooms or bathrooms at the state level. The real limits come from local zoning and the maximum size allowed for the accessory dwelling unit. As long as the ADU stays within the local size cap and building code, multiple bedrooms and bathrooms are usually allowed.

Are ADUs A Good Investment?

In much of New Mexico, they definitely are. Cities like Albuquerque and Santa Fe have steady rental demand and rising housing costs, which makes long-term rentals from casitas attractive. ADUs can create rental income, increase property value, and provide flexible housing for family members. However, short-term rental income may be limited by local permitting rules, and rural areas may have weaker rental demand. The smartest move is to check local rental demand, zoning rules, and permit costs before building to make sure the numbers make sense for your area. And if you’re owning an ADU to support your family members, this is an incredible investment of a different kind!

Does Bernalillo County, NM, Allow ADUs?

Yes it does! This is one of the most ADU-friendly parts of New Mexico, largely because Albuquerque has clear rules for casitas. Within Albuquerque city limits, one ADU is commonly allowed on residential lots, typically detached or attached, with size limits often around the 750–1,000 sq ft range depending on zoning. Long-term rental use is generally allowed, while short-term rentals may require separate permitting. Outside Albuquerque in unincorporated Bernalillo County, ADU rules are less clearly spelled out and often reviewed individually through zoning and building permits. Your next step is to contact Bernalillo County Planning & Development Services or the City of Albuquerque Planning Department depending on the property location.

Does Catron County, NM, Allow ADUs?

When it comes to Catron County, publicly available ADU or casita regulations are very limited. In this highly rural county, second dwellings are usually handled through general zoning and building permit review rather than formal ADU ordinances. Whether a casita can be used as a rental often depends on utilities, septic approval, and zoning classification. The best next step is to contact Catron County Planning or the County Assessor/Clerk’s office to ask about second dwellings or guest houses.

Does Chaves County, NM, Allow ADUs?

Even though it is not governed at a county level, it may be possible within certain cities. Roswell and surrounding areas allow accessory living quarters or guest houses in certain residential zones, but ADU-specific language is not consistently published at the county level. Projects are typically evaluated through zoning and building permit processes, and rental use depends on zoning approval. Start with Roswell Planning & Zoning or Chaves County Planning to confirm requirements for your property.

Does Cibola County, NM, Allow ADUs?

Just like its surrounding counties, clear ADU guidance is limited in Cibola County. Some municipalities may allow guest houses or second dwellings depending on zoning and lot size, but countywide casita rules are not well documented online. Rental use would generally require zoning approval and proper utilities. Contact Cibola County Planning & Zoning or the local municipality (such as Grants) for the most accurate guidance.

Does Colfax County, NM, Allow ADUs?

It is likely, but not confirmed yet. In rural areas and small towns, second dwellings may be possible depending on zoning and infrastructure, but formal ADU ordinances are not widely available. Each project is reviewed individually through zoning and building permits. Your next step is to contact Colfax County Planning or the relevant town planning office. They can answer your specific questions and point you in the right direction.

Does Curry County, NM, Allow ADUs?

Clear countywide ADU or casita regulations are not widely published. In the City of Clovis, secondary dwellings or guest houses may be possible depending on zoning, utilities, and lot size, but they are usually reviewed case-by-case rather than under a formal ADU ordinance. Rental use depends on zoning approval and permitting. Your next step is to contact Clovis Planning & Zoning or Curry County Planning to confirm what is allowed on your property.

Does De Baca County, NM, Allow ADUs?

Unfortunately, we can’t say for sure one way or the other, as the public ADU information is very limited.  This rural county generally handles second dwellings through standard zoning and building permit review rather than specific ADU rules. The best next step is to contact the De Baca County Clerk or local permitting office and ask about second dwellings or guest houses.

Does Doña Ana County, NM, Allow ADUs?

Yes, although it’s within city limits, not the county level. Las Cruces has clearer ADU guidance than most of the state. In the city, accessory dwelling units are allowed in certain residential zones and usually must remain secondary to the primary home. Size limits often depend on zoning, and owner occupancy may be required. Long-term rentals are typically allowed, while short-term rentals may require additional approvals. Outside city limits, county rules are less explicit and projects may be reviewed individually. Start with Las Cruces Community Development or Doña Ana County Planning.

Does Eddy County, NM, Allow ADUs?

Published countywide ADU regulations are limited which means you will need to start by confirming your zoning and lot eligibility.  In areas like Carlsbad, second homes or guest houses may be possible if zoning and parcel size allow, but every proposal typically goes through local review. Reach out to Carlsbad Planning & Zoning or Eddy County Planning to verify whether your property qualifies and ask what permits you’ll need to begin.This will eliminate any unnecessary research and wasted time.

Does Grant County, NM, Allow ADUs?

It isn’t certain one way or the other. Since specific ADU or casita regulations are not widely available online, your best move is to speak directly with local planners. Some communities may allow a second dwelling if zoning, utilities, and access requirements can be met, but approvals are often handled case-by-case. Contact Grant County Planning or the City of Silver City Community Development office to walk through your property details and learn the next steps for applying.

Does Guadalupe County, NM, Allow ADUs?

Published ADU or casita regulations are very limited. In small communities like Santa Rosa, second dwellings or guest houses may be possible depending on zoning, utilities, and septic approval, but formal ADU ordinances are not widely documented. Rental use would generally depend on zoning approval. The next step is to contact Guadalupe County Planning or the local municipal office to ask about second dwellings or guest houses.

Does Harding County, NM, Allow ADUs?

There is little publicly available guidance on accessory dwelling units. In this very rural county, ADUs are typically reviewed through standard zoning and building permit processes rather than a formal ADU policy. Whether a casita can be rented will depend on zoning and infrastructure approvals. Contact Harding County officials or the county clerk’s office for direction on second dwelling approvals.

Does Hidalgo County, NM, Allow ADUs?

Formal ADU regulations are not clearly published. Secondary dwellings may be possible depending on zoning, lot size, and utilities, but projects are usually handled individually through the permitting process. Rental use would depend on zoning approval. The next step is to contact Hidalgo County Planning or the county clerk’s office for guidance. This direct communication will help speed up the process.

Does Lea County, NM, Allow ADUs?

It is unclear at this point. The fastest way to move forward is to verify your property’s zoning and permitted uses, since countywide ADU guidance is not clearly published online. In cities like Hobbs, second homes or guest houses may be possible in certain residential districts, but approval depends on local zoning, utilities, and permitting. Begin by contacting Hobbs Planning & Zoning or Lea County Planning to ask whether your parcel allows a second dwelling and what application steps are required.

Does Lincoln County, NM, Allow ADUs?

Since ADUs are not governed at a county level in Lincoln County, your first step should be checking the zoning and subdivision rules that apply to your lot, as Lincoln County regulations vary widely by community. Areas such as Ruidoso often allow guest houses or second dwellings on larger residential properties, but each project still goes through zoning and permit review. Reach out to Ruidoso Planning or Lincoln County Planning & Zoning to confirm eligibility and request guidance on the approval process.

Does Los Alamos County, NM, Allow ADUs?

Los Alamos has more structured planning than many rural counties, but clear countywide ADU guidance is still limited online. Start by speaking directly with the county to confirm whether your property meets current standards, since online ADU guidance is limited. Contact Los Alamos County Community Development to review your parcel details and learn the exact steps needed to apply for a casita or secondary unit.

Does Luna County, NM, Allow ADUs?

Like the rest of New Mexico counties, published ADU or casita regulations are minimal in Luna County. In and around Deming, second dwellings or guest houses may be considered depending on zoning, lot size, and infrastructure. Rental use would typically require zoning approval. Start by contacting Luna County Planning or the City of Deming planning office for guidance.

Does McKinley County, NM, Allow ADUs?

Clear ADU-specific language is limited at the county level. However, in Gallup and surrounding areas, second dwellings or guest houses are allowed depending on zoning and utilities, but projects are generally reviewed individually. Contact Gallup Community Development or McKinley County Planning for next steps and ask about size and permit requirements.

Does Mora County, NM, Allow ADUs?

Publicly available ADU guidance is very limited. In this rural county, casitas or second dwellings are typically handled through zoning and building permit review rather than a dedicated ADU ordinance. Rental use depends on zoning and utility approvals. Your next step is to contact Mora County officials or the county clerk’s office to discuss second dwelling requirements.

Does Otero County, NM, Allow ADUs?

While Alamogordo and surrounding communities may allow guest houses or second dwellings in certain residential zones, formal ADU regulations are not widely documented. Rental use depends on zoning and permitting and there are no clearly defined size and setback requirements.  Start with Alamogordo Community Development or Otero County Planning.

Does Quay County, NM, Allow ADUs?

Clear, countywide ADU regulations are hard to find, and in places like Tucumcari, secondary living spaces are usually evaluated through standard zoning and building review rather than a dedicated ordinance. If ADUs aren’t allowed on your property, you may want to explore options like a guesthouse permit, a manufactured home placement, or adding living space to the primary residence. Contact Quay County Planning or the Tucumcari planning office to confirm what pathways are currently available.

Does Rio Arriba County, NM, Allow ADUs?

As of right now, countywide rules specifically covering casitas or ADUs are not widely published, but communities like Española may allow second dwellings or guesthouses depending on zoning, septic capacity, utilities, and parcel size. Any plan to rent the unit would need to meet local zoning and permitting requirements. If ADUs aren’t permitted where you live, consider alternatives such as converting an existing structure or expanding the primary home to create separate living quarters. Reaching out to Rio Arriba County Planning & Zoning or the City of Española planning office is the best first step for up-to-date guidance.

Does Roosevelt County, NM, Allow ADUs?

Unfortunately, formal ADU ordinances are limited, and in Portales and nearby areas, proposals for secondary homes are typically reviewed individually through the zoning and permitting process. Approval often depends on infrastructure availability, zoning, and lot size, and rental use would require additional authorization. If ADUs aren’t an option on your lot, you might look into guesthouse approvals, subdividing land, or placing a small manufactured home if zoning allows. Contact Roosevelt County Planning or the City of Portales planning office to learn what options may work for your property.

Does Sandoval County, NM, Allow ADUs?

It sure does! Within the county, Rio Rancho has some of the clearer local guidance in the county and allows casitas in certain residential zones, often depending on lot size and setbacks. Detached units are more likely to be allowed on larger lots, and rental use may be permitted with proper zoning and permits. Outside municipal areas, rules are less clearly defined and may be handled individually. Start with Rio Rancho Planning & Zoning or Sandoval County Community Development.

Does San Juan County, NM, Allow ADUs?

Yes, although it is not decided at the county level. Within the city of Farmington, ADUs are permitted and encouraged. Outside of the city, ADUs are less standardized and reviewed on an individual level. For more information, contact Farmington Planning & Zoning or San Juan County Community Development.

Does San Miguel County, NM, Allow ADUs?

As of now, published ADU regulations are very limited. In Las Vegas (NM) and surrounding communities, guest houses or second dwellings are possible depending on zoning, lot size, and utilities, but formal ADU ordinances are not widely documented. Rental use would require zoning approval. Contact San Miguel County Planning or the City of Las Vegas planning office for guidance.

Does Santa Fe County, NM, Allow ADUs?

Yes! Santa Fe is one of the most ADU-friendly areas in New Mexico and frequently uses the term casita. Within the City of Santa Fe, accessory dwelling units are allowed in many residential zones as either attached or detached homes. Size limits and setbacks depend on zoning and historic district rules, and design review may be required in some neighborhoods. Outside the city, county rules are less standardized and often reviewed individually. Start with the Santa Fe Planning & Land Use Department for property-specific requirements.

Does Sierra County, NM, Allow ADUs?

Following the pattern of almost all the New Mexico counties, Sierra County does not have county level published ADU regulations. In communities like Truth or Consequences, second dwellings or guest houses are very likely possible, even if it isn’t under the name of ADU. The next step is to contact Sierra County Planning or the Truth or Consequences planning office and confirm exactly what additional dwelling units are allowed on a lot.

Does Socorro County, NM, Allow ADUs?

Like other New Mexico counties, Countywide rules specifically addressing ADUs are not clearly defined, so proposals for second living spaces are usually evaluated individually through zoning and building permit review. If an ADU isn’t permitted on your property, consider exploring guesthouse approvals or subdividing the lot if zoning allows. Reaching out to Socorro County Planning or the City of Socorro planning office is the best way to confirm current requirements.

Does Taos County, NM, Allow ADUs?

It is very possible. Taos communities are often supportive of small secondary homes like casitas, particularly in rural or traditional residential areas, though local rules can vary widely by municipality and subdivision. However, the lack of available public information makes it difficult to confirm size, setback, and other zoning requirements. Start by speaking with the Taos Planning Department to understand the most up-to-date zoning and permitting expectations.

Does Torrance County, NM, Allow ADUs?

When it comes to ADUS, Clear countywide standards in Torrance County are limited, but second homes or guest quarters may be considered in municipalities such as Moriarty or Estancia depending on zoning, lot size, and access to utilities. Any rental use would likely need additional approvals and compliance with local land-use rules. If an ADU isn’t an option, consider applying for a guesthouse permit or exploring a manufactured home placement if zoning supports it. Contact Torrance County Planning or the relevant town office to verify what pathways are available.

Does Union County, NM, Allow ADUs?

Public ADU guidance is very limited in Clayton and surrounding areas. ADU language is not used in the zoning codes, but second dwellings may be reviewed through standard zoning and building permit processes rather than a formal ADU ordinance. Your next step is to contact Union County officials or the local planning office and ask how they would define an ADU. It’s possible they are defining it under the term of casita, detached unit, or another name that is further developed.

Does Valencia County, NM, Allow ADUs?

It isn’t very clear. In Los Lunas, Belen, and nearby communities, formal ADU language is limited at the county level. Secondary dwellings may be allowed depending on zoning and lot size, but projects are often reviewed individually through zoning and building permits. Rental use depends on zoning approval. Start with Valencia County Planning & Zoning or the planning office of the relevant municipality.

Does Albuquerque, New Mexico, Allow ADUs?

It sure does! Albuquerque has some of the clearest casita rules in New Mexico. The city allows accessory dwelling units in many residential zones as either attached or detached homes. In most cases, only one ADU is allowed per lot and it must remain secondary to the primary residence. Size is typically capped at about 750 sq ft for detached units, though zoning and lot size can affect the exact limit. Owner occupancy is commonly required for either the main home or the casita. Long-term rentals are generally allowed, but short-term rentals (like Airbnb) require separate permitting and may be restricted depending on zoning. Start with the City of Albuquerque Planning Department and review the Integrated Development Ordinance before applying for a building permit.

Does Las Cruces, New Mexico, Allow ADUs?

Yes, Las Cruces allows accessory dwelling units in certain residential zones, but the process is more zoning-dependent than in Albuquerque. ADUs must remain subordinate to the primary home and typically must meet lot size, setback, and parking requirements. Size limits vary by zoning district, and some areas require the property owner to live on site. Your next step is to contact Las Cruces Community Development and confirm zoning eligibility before designing your casita.

Does Rio Rancho, New Mexico, Allow ADUs?

Yes! Rio Rancho permits accessory dwelling units in specific residential zoning districts, often on larger lots. Detached casitas are more commonly allowed when lot size and setbacks can accommodate them. ADUs must be secondary to the main home and meet height, parking, and setback requirements. Rental use may be allowed with proper zoning and permitting, though short-term rentals may require additional approvals. Start by contacting Rio Rancho Planning & Zoning to verify your property’s zoning and development standards.

Does Santa Fe, New Mexico, Allow ADUs?

Definitely. Santa Fe is widely known for embracing casitas and has well-established rules. ADUs are allowed in many residential zones as attached or detached units. Size limits depend on zoning and neighborhood context, and historic districts may require design review. Long-term rentals are generally allowed, while short-term rentals require separate licensing and can be restricted in some areas. The next step is to work with the Santa Fe Planning & Land Use Department and review zoning and historic district requirements before applying for permits.

Does Roswell, New Mexico, Allow ADUs?

Yes, Roswell may allow accessory living quarters or guest houses in certain residential zoning districts, but the city does not publish a highly detailed ADU ordinance like larger cities do. Requirements such as setbacks, lot size, utilities, and parking typically determine whether a casita is approved. Rental use depends on zoning approval and permitting. Start by contacting Roswell Planning & Zoning to confirm whether your property qualifies for a second dwelling.

Does Farmington, New Mexico, Allow ADUs?

Yes! Farmington has a standalone ADU ordinance which allows for detached or attached ADUs. They have a size limit of 40% of the lot size, but don’t dictate a square footage. Long-term rental use is possible when there is owner occupancy in one of the units. Your next step is to contact Farmington Planning & Zoning and ask specifically about “accessory living quarters” or “second dwellings.”

Does Hobbs, New Mexico, Allow ADUs?

Hobbs may allow secondary residences or guest houses in certain residential zoning districts, but formal ADU language is not clearly emphasized online. Approval usually depends on zoning, lot size, utilities, and parking. Rental use will depend on zoning and permitting, and short-term rentals may require separate approval. Start with Hobbs Planning & Zoning to confirm whether your property can support a second dwelling.

Does Clovis, New Mexico, Allow ADUs?

It does not appear that Clovis has any clear ADU guidelines at this point, although this may change in the future. For now, you will need to contact Clovis Planning & Zoning and ask about secondary dwellings or accessory living quarters. This can bring clarity for specific questions about process and size requirements.

Does Carlsbad, New Mexico, Allow ADUs?

Carlsbad may allow a second dwelling or guest house in certain residential zones, though formal ADU rules are not heavily documented. Approval will depend on zoning, lot size, setbacks, utilities, and parking requirements. Start with Carlsbad Planning & Zoning to determine whether your property qualifies for a second dwelling.

Does Gallup, New Mexico, Allow ADUs?

Unfortunately, we can’t say one way or the other at this point. Gallup does not widely publish detailed ADU regulations online and other zoning information is limited.  However, second dwellings or guest houses may be possible depending on zoning and utilities. You could also pursue a conditional use permit or zoning variance if the city doesn’t initially allow ADUs.  Contact Gallup Community Development and ask about guest houses or second dwelling units as your next step.

Does Los Lunas, New Mexico, Allow ADUs?

Los Lunas does not clearly publish a dedicated ADU or casita ordinance. However, second dwellings or guest houses may be allowed depending on zoning, lot size, utilities, and setback requirements. Approval is typically handled through the zoning and building permit process rather than a standardized ADU program. Long-term rental use would depend on zoning approval, and short-term rentals may require additional permits. Your next step is to contact the Village of Los Lunas Planning & Zoning Department and ask about casitas or ADUs.

Does Sunland Park, New Mexico, Allow ADUs?

It isn’t certain as of now. Sunland Park does not widely publish formal ADU regulations and projects are generally reviewed individually through zoning and permitting. Start with Sunland Park Community Development and ask about second dwelling units or accessory living quarters. The staff can point you in the right direction and give more clarity on what may be allowed, even if it is not documented online.

Does Deming, New Mexico, Allow ADUs?

Like other New Mexico cities, Deming does not have a well-documented standalone ADU ordinance. Secondary dwellings may be allowed depending on zoning and utilities, but projects are typically reviewed case-by-case. Long-term rental use would depend on zoning approval. The next step is to contact the City of Deming Planning Department to confirm whether your property qualifies for a second dwelling.

Does Las Vegas, New Mexico, Allow ADUs?

Las Vegas, NM has limited publicly available ADU guidance. Because the city has many historic areas, it may be more of a challenge to get them approved for your property. To find out for sure, you can contact the City of Las Vegas Planning Department to ask about ADU regulations, including permit processes, size, setbacks, etc.

Does Artesia, New Mexico, Allow ADUs?

Like other more rural areas of New Mexico, Artesia does not clearly publish a dedicated ADU ordinance. Secondary dwellings or guest houses may be possible depending on zoning and infrastructure, and projects are typically reviewed individually through zoning and building permits. You can also consider a conditional use permit or zoning variance to have it allowed.  Your next step is to contact Artesia Planning & Zoning and ask about secondary residences or accessory living quarters.
