Costs people forget to budget for
- Permit. Water heater replacements in the City of LA need a permit from the Department of Building and Safety, unless your contractor is LADBS-certified to self-permit. Ask your plumber who pulls it.
- Earthquake straps. California requires water heaters to be strapped or braced. Expect this on every install.
- Venting and gas line upgrades. Older homes often need new venting. Switching to tankless usually needs a bigger gas line.
- Electrical work. Heat pump models may need a new circuit or a panel upgrade.
- Expansion tank and haul-away. Often required by code and often left off cheap quotes.
- Emergency and weekend calls. Expect a premium if the old tank fails at night.
Repair or replace?
Repair if the tank is under about 8 years old and the problem is a part like a thermostat, element or relief valve. Replace if the tank is 10 or more years old, leaks from the tank itself, or has rusty water. A leaking tank cannot be fixed.
How to get a fair price
- 1Get at least 3 written quotes for the same model and size.
- 2Confirm each quote includes permit, straps, haul-away and any venting work.
- 3Ask how long the warranty is on both the unit and the labor.
- 4Check that the plumber has an active California C-36 plumbing license.
Frequently asked questions
How long does replacement take?
A same-type tank swap usually takes 3 to 5 hours. Tankless conversions often take a full day.
Is tankless worth it in LA?
It lasts longer and never runs out of hot water, but it costs about twice as much upfront. It makes the most sense if you plan to stay in your home for years.
Are there rebates?
Heat pump water heaters often qualify for rebates from LADWP and statewide programs. Amounts change often, so ask your plumber or check before you buy.
What size do I need?
40 gallons for 1 to 3 people, 50 gallons for 3 to 5 people.
