Do you need a building permit in Roosevelt County, New Mexico?

Roosevelt County has no county building department of its own, so the state's Construction Industries Division enforces New Mexico's building codes and issues permits in unincorporated areas; covered residential construction requires a permit before work begins unless an exemption applies^1,2. New Mexico lists the 2021 residential and commercial building codes and the 2020 electrical code; the 2024 plumbing and mechanical codes took effect August 1, 2026, with dual permitting through the transition to January 1, 2027¹¹. Exempt work includes one-story detached storage sheds and playhouses up to 120 square feet, fences up to 6 feet, and qualifying detached decks up to 200 square feet that sit no more than 30 inches above grade; separate trade permits may still apply¹². A property owner may use a homeowner permit only for the owner's primary single-family residence and qualifying appurtenant structures, and the owner must complete the major portion of the work by dollar amount⁶. Licensed contractors must handle subcontracted work and obtain the appropriate trade permits; homeowner permits cannot cover HVAC, natural-gas or LP-gas installations⁶.

Who issues building permits in Roosevelt County, and how do you reach them?

Roosevelt County has no county building department, so the state Construction Industries Division (CID) issues building permits for unincorporated land.

Roosevelt County has no county building department, so the state Construction Industries Division (CID) issues building permits for unincorporated land¹. CID's homeowner application requires county planning and zoning approval, the Multi-Purpose State Building Application, two complete plan sets and the applicable fee^6,13. Because county zoning is unconfirmed, ask Roosevelt County Planning/Rural Addressing what approval letter CID needs for the parcel^3,13. CID reports residential processing in 3 to 4 working days and issuance within 5 working days after a complete package arrives¹³. Building-permit fees depend on construction type, size, materials and cost; ask CID for the project amount⁹. CID offers online permitting¹⁴. The Albuquerque office is at 5500 San Antonio Dr. Suite F, Albuquerque, New Mexico 87109, (505) 222-9800¹.

Does Roosevelt County have zoning?

We could not confirm a general zoning ordinance for unincorporated Roosevelt County; ask Roosevelt County Planning/Rural Addressing about the parcel's land-use restrictions, setbacks and minimum lot or dwelling size³. Inside Portales, the city has its own zoning code; onsite septic permitting remains with the New Mexico Environment Department (NMED)^5,15. New Mexico allows municipal extraterritorial zoning jurisdiction even where a county has no comprehensive zoning ordinance, so land outside city limits still needs a jurisdiction check¹⁶. Ask county Planning/Rural Addressing and Portales which office controls a parcel near the city before relying on an unincorporated address^16,17.

How do septic permits work in Roosevelt County?

The New Mexico Environment Department (NMED) issues septic permits in Roosevelt County through its local field office.

The New Mexico Environment Department (NMED) issues septic permits in Roosevelt County through its local field office⁴. Obtain the septic permit before installing or modifying a system, or building, altering or moving a dwelling onto a lot that needs one¹⁸. The conventional-system permit fee is $225 for systems up to 1,000 gallons per day; applications require ownership, site, floorplan and supporting documents⁴. Request NMED inspection at least 48 hours (2 business days) ahead and do not cover the system before inspection⁴. Homeowner installations require a final NMED inspection, and the system needs final department approval before use or occupancy of a new dwelling that requires it^18,19. About 69.4% of county soil has no severe limitation for a conventional drain field, but each parcel still needs NMED review⁷. NMED lists the Clovis office at 100 E Manana, Unit 3, Clovis, NM 88101, 575-762-3728; call to confirm the office serving your parcel²⁰.

Can you live in an RV or tiny home on your land in Roosevelt County?

We could not confirm Roosevelt County's rules for residential RV use on unincorporated land, so ask county Planning/Rural Addressing before buying or moving onto a parcel.

We could not confirm Roosevelt County's rules for residential RV use on unincorporated land, so ask county Planning/Rural Addressing before buying or moving onto a parcel³. New Mexico allows a tiny house as a single dwelling on a permanent foundation when it provides complete independent living facilities and complies with the residential code and Appendix AQ²¹. The state definition caps a tiny house at 400 square feet excluding lofts²¹. A unit on a chassis with a permanent axle is treated as a recreational vehicle while the axle remains; removing the axles and placing the unit on supports or a foundation triggers the permanent-foundation tiny-house requirements²¹. A manufactured home requires a state installation permit and final inspection, while local placement rules can still apply²².

Building a home in Roosevelt County: the steps, in order

Ask Roosevelt County Planning/Rural Addressing about the rural address, floodplain status and the county approval letter CID requires; county zoning remains unconfirmed.

Ask Roosevelt County Planning/Rural Addressing about the rural address, floodplain status and the county approval letter CID requires; county zoning remains unconfirmed^3,13,17.
Obtain an Office of the State Engineer permit before drilling a private well⁸.
Submit the septic application to the local NMED field office and obtain approval before building or placing a dwelling that needs an onsite system^4,18.
Submit county approval, the Multi-Purpose State Building Application, two complete plan sets and the fee to CID^6,13.
Obtain NMDOT approval for new or modified state-highway access, and Floodplain Administrator approval before development in a Special Flood Hazard Area^23,24.
Keep covered construction visible until inspection approval; homeowner-permit holders must request and pass all required inspections, including the final inspection^25,26.
Request NMED inspection at least 48 hours ahead and leave the septic system uncovered until inspection⁴.
Obtain inspector approval for utility connections, NMED final approval for septic use, and a certificate of occupancy before moving into a homeowner-permitted home or addition^18,25,26.

What to check before you buy land in Roosevelt County

Water: Roosevelt County sees severe drought in 42% of years and averages only 16.1 inches of precipitation annually, so confirm well depth, water rights and reliability before you commit to a parcel.

Water: Roosevelt County sees severe drought in 42% of years and averages only 16.1 inches of precipitation annually, so confirm well depth, water rights and reliability before you commit to a parcel⁷. A private well requires an Office of the State Engineer permit before drilling, and the listed permit expires unless the well is completed within one year⁸. Soils: 69.4% of the county's soil has no severe limitation for a conventional septic drain field, but the parcel still needs NMED review⁷. Subdivision: Roosevelt County regulates covered land divisions; its claim-of-exemption process requires supporting documents and a notarized filing, and the County Manager or designee must respond within 30 days¹⁰. A qualifying agricultural parcel of at least 35 acres must have been used primarily and continuously for agriculture during the preceding three years¹⁰. Access: direct access to a state highway needs a New Mexico Department of Transportation permit before construction or modification²³. Taxes: Roosevelt County's effective property tax rate is about 0.4%, with a median bill near $593 a year⁷.

Watch-outs

Whether Roosevelt County has adopted a general zoning ordinance is unconfirmed, not settled as "no zoning" — verify directly with the county before assuming any use, setback or RV/tiny-home rule does or doesn't apply to your parcel³.
A Roosevelt County homeowner-permit project requires a certificate of occupancy before the home or addition is occupied; failure to request final inspection can bring a penalty of up to $500²⁶.
Confirm the NMED field office serving your Roosevelt County parcel before submitting a septic application; applications must go to the office with jurisdiction¹⁸.

Owner-builder exemptionConditional
A New Mexico property owner constructing or altering the owner’s single-family primary residence, including permitted appurtenant structures, under a homeowner’s permit.
- The exemption is limited to construction or alteration of the owner’s primary residence; other use cancels the current permit and can result in denial of later homeowner permits.
- The homeowner must comply with CILA, NMAC rules, applicable standards and codes, and may act as the general contractor only when the major portion of the work, based on dollar amount, is completed by the homeowner.
- A permit is required for all construction-related work for which a permit is required by statute or rule; the rule does not exempt the owner-builder from state permitting or inspections.
- Homeowner permits are limited to single-family dwellings and appurtenant structures such as private garages, carports and sheds, require proof of ownership, and are subject to AHJ approval.
- The application requires an AHJ-approved application, signed and notarized responsibility sheet, acknowledgement of the homeowner-permit instructions, local zoning approval, floodplain determination, proof of identity and ownership, and payment of required fees.
- Separate homeowner permits may be issued for general building construction, mechanical/plumbing and electrical work; each is limited to the primary residence and does not apply to rental property, other owned property, or commercial work or property.
- The homeowner is responsible for requesting inspections, correcting code violations, and requesting re-inspections for a certificate of occupancy or final inspection. Subcontractors remain responsible for permits, inspections and corrections for plumbing, mechanical and electrical work they perform.
- The homeowner may perform authorized work personally or with W-2 employees, or subcontract part of the work while self-performing a significant portion. Subcontracted work must be performed by licensed contractors who obtain their own permits and pass required inspections.
- A homeowner permit is invalid for a project managed, supervised or acted on as general contractor by a GB-2 or GB-98 contractor; that contractor must obtain the appropriate permits and assumes responsibility for the site work.
- Single-scope projects such as roofing or window installation are ineligible when subcontracted and not performed by the homeowner or valid W-2 employees.
- Plumbing requires sufficient knowledge as determined by the TBC or CBO; a written examination with a minimum passing score of 75% may be required, failed examinations may not be repeated sooner than 30 days, and permitted plumbing work must be performed by the permittee.
- Electrical work requires approved plans or drawings and a CID homeowner electrical exam with a minimum passing score of 75%; failed examinations may not be repeated sooner than 30 days, and permitted electrical work must be performed by the permittee.
- A homeowner permit may not be issued for HVAC, natural gas or LP gas installations. HVAC and natural-gas work requires a properly licensed contractor and AHJ permitting and inspection; LP-gas work requires a properly licensed contractor and permitting and inspection through the LP gas trade bureau.
- A homeowner-permit project may not be placed on the market for sale while under construction; doing so automatically voids the permit and may lead to unlicensed-contracting charges.
- No more than one homeowner permit for a single-family dwelling may be issued to the same property owner within any 12-month period.
- The cited rule section states an adoption/replacement date of March 10, 2022.
homeowner electrical exam minimum passing score: >= 75 percent (Required after plan approval for issuance of a homeowner electrical permit.) · homeowner plumbing exam minimum passing score: >= 75 percent (The TBC or CBO may require the written examination.) · failed homeowner exam retest interval: >= 30 days (Failed plumbing and electrical examinations may not be repeated sooner.) · homeowner permits per single-family dwelling and property owner: <= 1 per 12 months
“A homeowner permit allows homeowners to obtain permits for constructing or altering their primary residence without becoming a licensed contractor is strictly limited to construction and alteration of their primary residence. Any other use of a homeowner’s permit shall result in cancellation of the current homeowner permit and denial of any subsequent request for a homeowner permit. The homeowner licensing exemption requires conformity with CILA, its rules, standards and codes. This includes a homeowner acting as a general contractor for the project. The homeowner’s permit authorizes the homeowner to physically perform the work, alone or with legal employees, or act as a general contractor and subcontract portions of the work to licensed contractors. In order to qualify for the homeowner permit the major portion of the work to be performed, based on dollar amount, must be completed by the homeowner.

Water rights & wells in Roosevelt County

Whether a new home can legally get its own water here — the sub-state groundwater regime, from New Mexico’s water agency.

Actively managed

This basin is under active state management — new water use is scrutinized, though a domestic well is usually still allowed.

Household wellPermit required (issued by right)

Nearly all developed New Mexico lies inside an OSE 'declared' underground water basin, but a household 72-12-1.1 domestic well is a by-right permit the State Engineer issues even in closed/over-appropriated basins (metering can be required). The by-right amount is cut to 0.25 acre-ft/yr in a declared Domestic Well Management Area, and a few basin-specific orders cap it further (Gallup Order 197, Zuni Order 199) or stop issuing new domestic permits entirely (Hot Springs Order 198).
