HVAC Permit rules nationwide, beyond New Mexico.

Requirements and size thresholds for HVAC permits vary by locality. The table below compares what each New Mexico county or city requires. Always confirm with the local office before starting.

Comparing states? See HVAC permit rules across every locality we cover.

The application steps and inspection sequence for HVAC permits come from the model code rather than from New Mexico law, so they read the same wherever you build. We keep that walkthrough in one place: how an HVAC permit application and its inspections work, start to finish. What changes between New Mexico jurisdictions is below: who requires a permit, what they charge, and which office you file with.
