New Mexico building departments

How permitting works in New Mexico

State permits unless a full-service local department exists. In New Mexico, permits come from the state Construction Industries Division unless the city or county runs a full-service building department with a certified building official. Only CID-licensed contractors can pull permits, apart from homeowner permits for a primary residence.

A county name is only a geographic starting point. Depending on the address, a city, town, borough, township, or county office may issue your permit. How to check who issues your permit.

Outside city limits

The permitting authority is either the state (CID) or a city or county that runs a full-service building department with a certified building official. Where no such local department exists, CID issues permits and does inspections.

Contractor licensing

Only a CID-licensed contractor can apply for a permit. The exception is a homeowner permit, which lets an owner build or alter their own primary residence without a contractor license. CID also certifies journeymen and runs separate electrical, mechanical-plumbing and LP gas bureaus. Construction Industries Division (CID) (opens in a new tab)

What is different in New Mexico

• Every re-roof and roof-coating job needs a building permit and inspections under the state permit rule (14.5.2 NMAC).
• The 2024 New Mexico Plumbing Code and Mechanical Code took effect August 1, 2026. Permits may be issued under either the 2021 or 2024 edition until January 1, 2027; after that, only the 2024 edition applies.
• New Mexico keeps state codes for earthen (adobe and rammed earth) construction and non-load-bearing straw bale construction, as well as historic earthen buildings.
• A homeowner permit covers only the owner's primary residence. Using it for any other purpose cancels the permit, and future homeowner permits can be denied.
