Permit required
Do you need a permit for HVAC Installation in Monterey County?
In California, a HVAC Installation requires a mechanical permit.
Installing or replacing HVAC equipment requires a mechanical permit and inspection under California's Mechanical Code; even a same-size swap generally needs one. Routine maintenance is exempt, and a gas-to-heat-pump conversion also triggers an electrical permit and Title 24 energy compliance. Plans are reviewed under the Statewide (CA Codes) code (IRC 2024); apply through Monterey County Building Services before work begins.
