mechanical + electrical permit
As of 2026-05-31, heat pump HVAC installations in San José require a mechanical permit issued by the Planning, Building and Code Enforcement (PBCE) Department. An electrical permit is typically also required when a new dedicated circuit is added or the electrical panel needs an upgrade to support the new equipment. Permit application is submitted via the SJPermits.org online portal for single-family and duplex residences. California Title 24 Building Energy Efficiency Standards and HERS verification may apply depending on system size and scope. Like-for-like replacements may qualify for an over-the-counter / express path; new installations or system changes typically require plan check. Verify the current submission requirements and any seismic, energy-code, or refrigerant constraints with the Building Division before scheduling installation.
