The Los Angeles market
The Los Angeles Department of Building and Safety (LADBS) treats water heater replacement, gas furnaces under 500,000 Btu per hour and same-size, same-type A/C swaps as express permits with no plan check. Heat pumps are not named on that list. A single-family owner can pull the permit as owner-builder with proof of ownership, and a contractor's agent needs a notarized authorization dated within the past year. An LADBS field inspector signs off the work. State law adds a seismic layer: California Health and Safety Code 19211 requires every new and replacement water heater to be braced, anchored or strapped. Gas dominates water heating, with EIA counting 78% of California homes using it in 2020. Long Beach, Anaheim and other cities in the metro run their own departments, so confirm which office covers your address.
Expect two straps on the new tank. LADBS bracing guidance says one goes in the upper third and one in the lower third, with the lower strap at least 4 inches above the control. Ask the plumber to show you both before they leave. If you sell later, state law requires you to certify in writing that the heater is braced. For a tank in the garage, ask about a drain pan and where the relief line discharges.
