Most Los Angeles-area homeowners pay roughly $1,100 to $2,800 to replace a standard 40- or 50-gallon gas tank water heater, installed. A tankless conversion usually runs $3,500 to $6,800. Where you land depends on the size, the fuel, and how much of your old setup has to be brought up to code. Here's how the numbers break down for Burbank, Glendale and the rest of LA, and what makes one quote $800 higher than another.
Typical 2026 prices in the LA area
These are published ranges from cost guides and local installers. Treat them as a sanity check, not a quote.
| Job | Typical installed range | Source |
|---|---|---|
| Water heater replacement, all types (LA average) | $1,140–$2,410 (avg. about $1,740) | Angi |
| 40-gallon gas tank, like-for-like swap | $1,650–$2,400 | LA installer pricing (Venta) |
| 50-gallon gas tank, like-for-like swap | $1,850–$2,800 | LA installer pricing (Venta) |
| Gas or electric tank, 40–50 gal (broad LA range) | $1,100–$2,500 | Plumbing Connection LA |
| Gas tank to tankless conversion | $4,400–$6,800 | LA installer pricing |
| Heat pump (hybrid) water heater | $3,500–$7,000 before rebates | LA installer pricing |
Why the wide spread? The tank itself is usually only $550 to $1,500 of the bill. The rest is labor, connectors, venting, permits, code items, and hauling the old tank away. A garage swap with valves that still turn sits at the low end. A 1930s Glendale bungalow with a closet heater, a tired flue and no earthquake straps sits at the top.
What actually moves the price
1. Size and fuel
A 40-gallon tank usually covers 1–3 people, and a 50-gallon covers about 3–5. Most Burbank and Valley houses have gas heaters, and gas-to-gas is the cheapest swap. Going from gas to electric, or to a heat pump, can mean a new 240-volt circuit. Going to tankless often means a bigger gas line.
2. Code items California requires
California law requires water heaters to be braced or strapped against earthquakes. Most replacements also need a proper temperature-and-pressure relief line, and many need a drip pan or a gas sediment trap. Some jurisdictions and newer homes require an expansion tank. Local installers list expansion tanks at about $145–$245 and strap upgrades at about $85–$165. A cheap quote often leaves these off, so ask.
3. Permits: Burbank, Glendale and LA each have their own
A water heater replacement normally needs a permit and inspection. In the City of Los Angeles that goes through LADBS. Burbank and Glendale run their own building departments, so fees and inspection timing differ. Ask your plumber whether the permit is included and who books the inspection. A permitted, inspected install also helps when you sell, because California sellers have to certify that the heater is braced.
4. Venting and location
Older homes often have flues that need new sections, and heaters in interior closets take longer to swap than garage units. Moving the heater to a new spot adds gas, water and vent runs. That's where an "easy" $1,800 job turns into a $3,000 one.
5. Timing
Tanks rarely fail at a convenient time. Some companies add an after-hours or same-day premium. One LA installer lists $150–$300 for evening dispatch. Ask before you agree to the visit.
Tank or tankless for an LA home?
A tankless heater gives you endless hot water and frees up floor space, and it typically outlasts a tank. The Department of Energy puts tank heaters at about 10–15 years and tankless units at 20+. But the conversion costs two to three times as much. Many older Valley homes also need a larger gas line, because a whole-house tankless unit can draw roughly five times the gas of a 40-gallon tank. In our mild climate, energy savings alone rarely pay back the difference quickly. Tankless makes the most sense if you're staying long-term, you run out of hot water now, or you want the garage space back. See tankless water heater installation for what's involved, and our tank vs tankless cost breakdown for the full math.
Rebates and tax credits in 2026
- SoCalGas offers rebates on qualifying high-efficiency gas water heaters, including tankless. Amounts depend on the efficiency rating, so check the current program before you buy. Our tankless cost guide lists the 2026 tankless tiers.
- Your electric utility (LADWP, Burbank Water and Power, or Glendale Water & Power) may offer rebates on heat pump water heaters. Programs change, so confirm eligibility first.
- The federal 25C energy-efficiency tax credit ended for equipment placed in service after December 31, 2025, according to the IRS. A 2026 quote that subtracts a federal credit is out of date.
Repair or replace?
Not every water heater problem means a new tank. A bad thermocouple, gas control, element, or relief valve can often be fixed. A leak from the tank itself (not a fitting), rusty hot water, or a tank past about 10–12 years usually means replacement. Our guide to 7 signs your water heater is dying walks through it, and water heater repair or replace? does the cost math. Regular flushing helps a lot in the Valley, where hard water leaves sediment in the tank.
How to compare quotes
- Get it in writing with the brand, gallons and fuel type listed.
- Ask what's included: permit, straps, expansion tank, new flex connectors, haul-away of the old tank.
- Check the license. Plumbing work in California should be done by a contractor with a C-36 license. You can look one up free on the CSLB website.
- Ask about warranties on both the tank and the labor.
