Do I need a permit for addition or structural alteration in Portales?

Permit required

Yes. In New Mexico, addition or structural alteration generally requires a permit, and Portales is no exception.

No building may be erected, enlarged, altered, repaired, improved, converted, or demolished without a permit from the AHJ unless 14.5.2.9 NMAC exempts the work (14.5.2.8(A) NMAC). CID's guide requires a seal by a New Mexico architect or structural engineer for a second-story addition over an existing first story unless proof of earlier CID approval shows it will carry the load. The plans must show that an existing sleeping room's only exit is not blocked by the addition (CID residential permit guide). Which office issues the permit depends on the address: a city or county with its own certified building department, or CID in all other areas (14.5.1.7 NMAC; NMSA 60-13-41).
