Do you need a building permit in New Mexico?

Usually it depends on the size of the job, and the size that decides it is not set by New Mexico: permits are issued by the city or county, not the state, so the rule that governs your project is the one your own jurisdiction publishes. 10 of those local rules require a permit outright, 16 depend on a size or scope condition the office publishes, and 0 need none. New Mexico sets the building code those local rules derive from; your city or county sets the threshold and the fee.

Do New Mexico jurisdictions agree?

Every row below is a measurement at least two New Mexico jurisdictions publish, compared against each other. This is the question a statewide answer cannot settle, because the number that governs your project is the one your own city or county publishes.

Project	Published threshold	Jurisdictions	Agreement
Pool	24 to 54 inches	2	2 different numbers
Deck	30 inches	2	Same number in all 2
Shed	120 sq ft	2	Same number in all 2

Building without a permit in New Mexico

New Mexico runs permitting statewide under the Construction Industries Licensing Act (CILA): the Construction Industries Division (CID) of the Regulation and Licensing Department, or a city or county building department enforcing the same state codes, is the authority having jurisdiction (AHJ). State rule 14.5.2.16 NMAC sets the failure-to-permit consequence for licensed contractors: when a licensee starts permit-required work before the permit is issued, the AHJ may charge twice the usual permit and inspection fees for a first violation, and later violations are disciplined under the administrative penalty in NMSA 60-13-23.1 ($300 to $500 where the work is $5,000 or less; above that, up to 10% of the value of the work but not less than $500; doubled for a licensee previously penalized, suspended or revoked).
