Do you need a building permit in Quay County, New Mexico?
Yes.
Yes.

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 County.
The New Mexico Construction Industries Division administers the state building-permit process applicable in Quay County7. CID's published residential guide lists its Albuquerque office at 5500 San Antonio NE, Albuquerque, NM 87109, phone (505)222-980011. 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 issuance7,12. General-building fees are published but vary with construction type, size, materials and cost; CID directs applicants to contact an office for the applicable amount9,13.
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 area.
Unincorporated Quay County has no prescriptive county zoning, and it does not publish county zoning districts or schedules for that area3. County zoning therefore sets no minimum dwelling size, minimum lot size, setback, lot-coverage limit or building-height limit there3. 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 disposal3. Municipal rules may apply inside incorporated places, so confirm the parcel's jurisdiction before relying on the unincorporated-county answer3.

Unincorporated Quay County has no county zoning restriction on RV occupancy or temporary camping3.

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 RV6. Manufactured homes require a state installation permit before setup and a final inspection for occupancy16. Quay County zoning sets no minimum dwelling size in unincorporated areas, but state construction and health rules still apply3.

What should you check before buying land in Quay County?
Start with water, sanitation, legal access and flood exposure.
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 closing8. About 52.7% of county soils lack severe limitations for a conventional drain field, but only a parcel-level evaluation answers the septic question8. 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 buildings7. Development in a special flood hazard area requires a Quay County floodplain-development permit4.
