Virtually every aspect of commercial, residential, and public works construction is regulated at the state level in New Mexico. This includes general, mechanical, plumbing, electrical, and gas construction work.

Homeowners performing work themselves or contracting with licensed sub-contractors are exempt from the licensing requirements. However, such homeowners must obtain a Homeowners Permit, inspections and a Certificate of Occupancy from the state. The Homeowners Permit exemption only applies to general construction. It does not automatically cover electrical, mechanical, plumbing, or gas work. This work must be performed by properly licensed contractors unless, in the case of electrical or plumbing work, an exam is passed by the homeowners.
