Mechanical permit or Simple No-Plan MEP eligibility check for HVAC replacement
City of San Diego DSD says mechanical systems may not be installed, altered, replaced, or repaired without a Mechanical Permit unless exempt, and its Simple Permit materials list minor HVAC-related items such as forced-air units, air conditioner units, exhaust fans, and furnace replacements for eligible residential properties. HVAC replacement should be matched to the actual equipment, building type, historic status, ductwork, electrical, gas, plumbing, and building scope before selecting the City permit path.
