Who to call
Building permits
New Mexico Construction Industries Division (CID) — Albuquerque Office
Statewide building permits and inspections for one- and two-family dwellings in areas without a local building department, including unincorporated Roosevelt County. CID has only three field offices statewide (Albuquerque, Santa Fe, Las Cruces) and no branch in or near Roosevelt County; most applicants use CID's online permitting portal rather than visiting in person.

Septic permits

On-site liquid waste (septic) permits statewide, including Roosevelt County. NMED's contact page does not state which field office is officially assigned to Roosevelt County; Clovis is NMED's nearest Liquid Waste field office to Portales, so call to confirm before you apply.

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 applies12. 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, 202713. 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 apply14. 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 amount8. Licensed contractors must handle subcontracted work and obtain the appropriate trade permits; homeowner permits cannot cover HVAC, natural-gas or LP-gas installations8.
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 land1. CID's homeowner application requires county planning and zoning approval, the Multi-Purpose State Building Application, two complete plan sets and the applicable fee1516. Because county zoning is unconfirmed, ask Roosevelt County Planning/Rural Addressing what approval letter CID needs for the parcel315. CID reports residential processing in 3 to 4 working days and issuance within 5 working days after a complete package arrives15. Building-permit fees depend on construction type, size, materials and cost; ask CID for the project amount11. CID offers online permitting17. The Albuquerque office is at 5500 San Antonio Dr. Suite F, Albuquerque, New Mexico 87109, (505) 222-980018.
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)619. 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 check20. Ask county Planning/Rural Addressing and Portales which office controls a parcel near the city before relying on an unincorporated address2021.
How do septic permits work in Roosevelt County?
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 one22. The conventional-system permit fee is $225 for systems up to 1,000 gallons per day; applications require ownership, site, floorplan and supporting documents7. Request NMED inspection at least 48 hours (2 business days) ahead and do not cover the system before inspection5. Homeowner installations require a final NMED inspection, and the system needs final department approval before use or occupancy of a new dwelling that requires it2322. About 69.4% of county soil has no severe limitation for a conventional drain field, but each parcel still needs NMED review9. NMED lists the Clovis office at 100 E Manana, Unit 3, Clovis, NM 88101, 575-762-3728; call to confirm the office serving your parcel24.
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 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 AQ25. The state definition caps a tiny house at 400 square feet excluding lofts25. 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 requirements25. A manufactured home requires a state installation permit and final inspection, while local placement rules can still apply26.
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 unconfirmed21315.
- Obtain an Office of the State Engineer permit before drilling a private well10.
- Submit the septic application to the local NMED field office and obtain approval before building or placing a dwelling that needs an onsite system422.
- Submit county approval, the Multi-Purpose State Building Application, two complete plan sets and the fee to CID1516.
- Obtain NMDOT approval for new or modified state-highway access, and Floodplain Administrator approval before development in a Special Flood Hazard Area2728.
- Keep covered construction visible until inspection approval; homeowner-permit holders must request and pass all required inspections, including the final inspection2930.
- Request NMED inspection at least 48 hours ahead and leave the septic system uncovered until inspection5.
- 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 addition312232.
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 parcel3334. 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 year10. Soils: 69.4% of the county's soil has no severe limitation for a conventional septic drain field, but the parcel still needs NMED review9. 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 days12. A qualifying agricultural parcel of at least 35 acres must have been used primarily and continuously for agriculture during the preceding three years12. Access: direct access to a state highway needs a New Mexico Department of Transportation permit before construction or modification27. Taxes: Roosevelt County's effective property tax rate is about 0.4%, with a median bill near $593 a year3536.
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 $5003230.
- Confirm the NMED field office serving your Roosevelt County parcel before submitting a septic application; applications must go to the office with jurisdiction22.
