The San Diego market
The City of San Diego's Development Services Department requires a Simple MEP (no-plan) permit to replace a water heater, furnace, condensing unit, heat pump package unit or mini-split in a single-family home or duplex. Repair only needs no permit. One local quirk: the simple route covers water heater replacements except tankless types. Homeowners, property owners and licensed contractors may apply, and owner-builders upload Form DS-3042. An inspection can be scheduled once the invoice is paid and the permit issued. Per-item fees are listed as $122.97 for a water heater, $176.57 each for a furnace, heat pump package unit or mini-split and $131.52 for a condensing unit, though the city table should be checked directly. State law requires seismic bracing on every replacement water heater. Chula Vista, Carlsbad and other county cities issue their own permits.
Gas heats water in 78% of California homes, so most San Diego replacements are gas tanks. A seller must certify the seismic strapping in writing, so ask the plumber to note the straps on the invoice. For a tank in the garage, ask about a drain pan and where the relief line discharges. Ask whether the vent connector and gas flex line are being replaced, and whether haul-away is included.
