When you do need a permit
Replacing an HVAC system with the same type and capacity requires a mechanical permit in California, even for a like-for-like swap. California requires HERS testing to verify proper installation, refrigerant charge, and airflow. This is stricter than many other states.
Changing HVAC system type (e.g., gas furnace to heat pump, window units to mini-split) requires mechanical and often electrical permits. Title 24 energy calculations are required. California is encouraging heat pump adoption through incentives.
Installing a new central HVAC system where none existed requires mechanical, electrical, and building permits. This is a major project requiring ductwork, equipment installation, and full Title 24 energy compliance. A Manual J load calculation is required.
Modifying, replacing, or adding ductwork requires a mechanical permit. California requires duct sealing verification (HERS testing) for all duct modifications. Ducts must be sealed and insulated per Title 24 requirements.
