Unincorporated Bernalillo County, New Mexico requires building permits and operates its own permitting authority through Planning & Development Services12. County zoning also applies in unincorporated areas, so a parcel's district matters before you choose a house plan or land use3. Homeowners may qualify to build their own primary residence, but the permit, inspections and final approval still apply45.

Do you need a building permit in Bernalillo County, New Mexico?
Yes. Bernalillo County requires permits for covered construction in unincorporated areas and runs its own building authority through Planning & Development Services12. New Mexico requires a permit before regulated residential construction, alteration, repair, addition, relocation, conversion or demolition begins, although limited exemptions cover certain small projects10. Those exemptions include qualifying one-story detached accessory structures no larger than 120 square feet and fences no taller than 6 feet; separate trade permits may still be necessary10. Covered residential work follows the 2021 New Mexico Residential Building Code11. Ask the county about the exact permit set for the proposed work because we could not confirm the full countywide permit schedule or current county code editions.
Who issues Bernalillo County building permits, and how do you reach them?
Bernalillo County Planning & Development Services handles building permits, plan review and inspections in unincorporated Bernalillo County12. The office is at 415 Silver SW, Albuquerque, NM 87102; call (505) 314-0350 or email [email protected]12. The inspection line is (505) 314-0351, and office hours are Monday through Friday from 8 a.m. to 4:30 p.m.12. For a homeowner permit, the applicant must apply in person and provide identity and ownership proof, signed instructions, a notarized acknowledgement of responsibilities, zoning approval, a floodplain determination, the approved application, required plans and documents, and applicable fees13. County permit fee amounts were not confirmed, so request the current total before submitting.
Does Bernalillo County have zoning?
Yes. Bernalillo County zoning covers the county's unincorporated area3. The published zone atlas identifies county districts and sector-development-plan subcategories, but the atlas is a reference rather than a source for exact measurements or legal descriptions; obtain those from the Bernalillo County Clerk and consult the applicable sector plan where one applies14. Lot standards vary by district: the atlas identifies the A-1 Rural Agricultural zone with a 1-acre minimum and the A-2 Rural Agricultural zone with a 2-acre minimum9. Those examples do not establish the minimum for every parcel. Ask Planning & Development Services to confirm the parcel's district, allowed use and applicable dimensional rules at (505) 314-0350 or [email protected]15. We could not confirm countywide rules for setbacks, building height, lot coverage or minimum dwelling size.
How do septic permits work in Bernalillo County?
Bernalillo County Public Works administers onsite wastewater permitting for the county, while much of the urbanized area uses public sewer7. Contact the Wastewater / Onsite Liquid Waste Program before fixing a house location or system design16. Only about 25% of county soils lack severe limitations for a conventional septic drain field, so a parcel-level site evaluation is especially important17. State rules require untreated liquid waste to enter an approved permitted system, treatment unit or public sewer, apart from qualifying graywater18. We could not confirm Bernalillo County's permit steps, inspection requirements, exceptions or a direct phone number; ask Planning & Development Services at (505) 314-0350 to route you to Public Works if necessary12.
Can you live in an RV or tiny home on your land in Bernalillo County?
We could not confirm a Bernalillo County rule allowing long-term RV living or temporary camping on private land, so ask Planning & Development Services about the parcel's zoning before relying on an RV as housing15. New Mexico recognizes a tiny house as a dwelling with complete living facilities when it meets the residential code, is inspected and is placed on a permanent foundation; the state definition caps floor area at 400 square feet excluding lofts8. A tiny house that remains on a chassis with its permanent axle is treated as an RV instead8. County zoning still controls whether a residential use fits the parcel3. We also could not confirm a countywide minimum dwelling size, so do not treat the state tiny-house definition as zoning approval.
Building a home in Bernalillo County: the steps, in order
- Ask Planning & Development Services to confirm the parcel's zoning district and allowed residential use315.
- Obtain zoning approval and a floodplain determination, then assemble ownership proof, plans, documents and applicable fees for an in-person homeowner application if you qualify13.
- If the site needs onsite wastewater, contact county Public Works before finalizing the house and drain-field locations716.
- Apply for the county building permit before covered work begins110.
- Request every required inspection, correct violations and arrange re-inspections; electrical and plumbing work require separate permits and tests5.
- Obtain the certificate of occupancy or final inspection when the project requires it before treating the job as complete6.
What to check before you buy land in Bernalillo County
Start with zoning, legal parcel dimensions and wastewater feasibility. Bernalillo County's atlas is not a substitute for a legal description, and sector-plan subcategories require their own plan review14. Only about 25% of county soils lack severe limitations for a conventional drain field17. The county averages 11.7 inches of precipitation a year and experiences severe drought in about 39.1% of years, so confirm the lawful water source and realistic well capacity before closing1920. About 76.4% of county land has a slope of 15% or less, but parcel terrain can still constrain access, grading and septic placement21. If access connects directly to a state highway, New Mexico requires a state access permit before covered construction or modification22. The median property-tax bill is about $2,544 a year, with an effective rate near 0.9%2324.
Watch-outs
- A homeowner permit is limited to the owner's primary single-family residence and does not cover rental dwellings or commercial property4.
- A homeowner permit holder must request inspections, correct violations and obtain the certificate of occupancy or final inspection when applicable56.
- The rural agricultural district names do not create a general farming exemption from county building or development rules9.
- Bernalillo County's RV-occupancy, temporary-camping, setback and minimum-dwelling-size rules remain unconfirmed; ask Planning & Development Services about the specific parcel15.
