mechanical + electrical permit
As of 2026-05-31, residential heat pump HVAC installations in the City of San Diego typically require a mechanical permit (and an electrical permit when new dedicated circuits, panel work, or service modifications are in scope) from the Development Services Department (DSD). Like-for-like change-outs at the existing roof curb or pad location, with no structural modification and no change to gas-line scope beyond capping a removed gas furnace, typically qualify for a DSD Simple No-Plan Combination Permit filed online through the Accela-based permit portal (aca.accela.com/SANDIEGO), which is normally issued within two business days for single-family or duplex projects. Installations that change equipment location, require structural support modifications, or expand ductwork scope route through traditional plan review. Refrigerant work must be performed by an EPA Section 608-certified technician, and the contractor is typically required to be a C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) licensed contractor authorized to perform the work. Verify current Simple Permit eligibility, scope, and contractor-registration requirements with DSD before scheduling installation.
