Do you need a building permit in Quay County, New Mexico?
Yes. Building, structural, electrical, plumbing, mechanical and LP-gas work covered by New Mexico rules requires the applicable permit before work begins in Quay County, with separate permits required by trade14. CID administers the state building codes that apply in Quay County3. Permitted construction also requires inspections appropriate to the work and code; the complete schedule depends on the project215. After all required inspections are approved in order, covered buildings or portions of buildings require a certificate of occupancy; work that did not require a permit does not16.
Who is the Quay County building department, and how do you reach it?
The New Mexico Construction Industries Division administers the state building-permit process applicable in Quay County17. CID's published residential guide lists its Albuquerque office at 5500 San Antonio NE, Albuquerque, NM 87109, phone (505)222-980018. Because the guide lists multiple CID offices without assigning Quay County to one, ask CID where to send the application. CID publishes forms and an online permitting portal, and applicants must submit the approved application and compliant plans and pay applicable fees before permit issuance1920. General-building fees are published but vary with construction type, size, materials and cost; CID directs applicants to contact an office for the applicable amount2122.
Does Quay County have zoning?
Unincorporated Quay County has no prescriptive county zoning, and it does not publish county zoning districts or schedules for that area2324. County zoning therefore sets no minimum dwelling size, minimum lot size, setback, lot-coverage limit or building-height limit there925262728. Those answers concern county zoning only: building-code, septic, subdivision and floodplain requirements remain separate. Quay County regulates applicable subdivisions through technical state and local reviews, public hearings and infrastructure requirements for roads, water, liquid-waste disposal and solid-waste disposal5. Municipal rules may apply inside incorporated places, so confirm the parcel's jurisdiction before relying on the unincorporated-county answer4.
How do septic permits work in Quay County?
Onsite wastewater work subject to New Mexico liquid-waste rules requires a permit from the New Mexico Environment Department, with applications submitted to the local NMED field office78. Supporting material may include proof of ownership, a site diagram, floor plan and plat or survey documentation8. The Tucumcari District Office is at 113 W Center, Tucumcari, NM 88401, phone 575-461-1671, with office hours by appointment29. Request inspection at least 48 hours, or 2 business days, ahead and do not cover the system before inspection; approval leads to a Permit to Operate30. Homeowner installations require an NMED final inspection and may require inspections at additional stages31. About 52.7% of county soils lack severe limitations for a conventional drain field, so obtain a parcel-specific evaluation13.
Can you live in an RV or tiny home on your land in Quay County?
Unincorporated Quay County has no county zoning restriction on RV occupancy or temporary camping3233. County zoning likewise does not restrict tiny homes, manufactured homes or accessory dwellings there103435. These land-use answers do not waive building, sanitation, floodplain, subdivision, utility or private restrictions. A New Mexico tiny house on a permanent foundation must meet the residential code, while one retaining its chassis and permanent axle is treated as an RV11. Manufactured homes require a state installation permit before setup and a final inspection for occupancy36. Quay County zoning sets no minimum dwelling size in unincorporated areas, but state construction and health rules still apply9.
Building a home in Quay County: the steps, in order
- Confirm that the parcel is in unincorporated Quay County and identify subdivision or floodplain review; applicable subdivisions are regulated, and development in a special flood hazard area requires a floodplain-development permit56.
- Use CID's published application process and obtain the project-specific fee before permit issuance2021.
- If building as the owner, confirm eligibility: the homeowner permit is limited to the owner's primary residence, requires the owner to complete the major portion of the work, and does not waive permits or inspections1237.
What should you check before buying land in Quay County?
Start with water, sanitation, legal access and flood exposure. Quay County averages about 16.1 inches of precipitation annually and spends about 42.2% of years in severe drought, so verify the parcel's water source and realistic yield before closing3940. About 52.7% of county soils lack severe limitations for a conventional drain field, but only a parcel-level evaluation answers the septic question13. We could not confirm a general county-road driveway permit rule, so ask Quay County before cutting or changing county-road access. We also could not confirm whether a particular parcel must connect to public water or sewer; state rules require authority approval for utility or energy connections to regulated buildings38. Development in a special flood hazard area requires a Quay County floodplain-development permit6.
Watch-outs

- Unincorporated Quay County has no county zoning restriction on RV occupancy, but sanitation and parcel-specific floodplain or subdivision requirements still apply3286.
