New Mexico permit questions
Do you need a permit for home renovations in New Mexico?
New Mexico enforces a statewide code (New Mexico Residential Building Code, based on the IRC), so permit requirements are broadly consistent across the state, but the permit itself is issued by your city or county. Structural, electrical, plumbing, mechanical and envelope work almost always require one.
Can a homeowner pull their own permit in New Mexico?
Owner-builder permits allowed on owner-occupied property. Owner-builder status usually makes you responsible for code compliance and for any unlicensed work performed on the property, and many jurisdictions restrict resale within a year of the permit.
