The Gas Water Heater Ban Reaches San Jose in 2027

Starting January 1, 2027, it becomes illegal to sell or install a new gas water heater — tank or tankless, under 75,000 BTU — anywhere in the nine-county Bay Area, including all of San Jose and Santa Clara County. You can keep and repair your current unit, but once it needs replacing, the only legal option is a zero-emission heat pump water heater (HPWH). San Jose homeowners who switch now can stack utility and panel rebates worth $3,500 or more — and we handle the paperwork.

Sold Out in 2027

New gas water heaters — tank and tankless — can no longer be sold or installed in the Bay Area after Jan 1, 2027.

Repairs Still OK

You're not forced to remove a working gas unit. The rule only triggers when you replace it — your choice, your timing.

Heat Pump = Compliant

The zero-NOx replacement is an electric heat pump water heater — 3 to 4 times more efficient than gas.

2026 Is the Window

Switch on your terms now and skip the 2027 rush, inventory crunch, and emergency panel-upgrade delays.

How a Heat Pump Water Heater Actually Works

No flame, no gas line. A heat pump water heater — like the Rheem ProTerra we install — moves free heat out of the surrounding air and into your tank, running up to 4× more efficiently than gas. Here’s the 30-second tour.

Rheem ProTerra hybrid heat pump water heater
4×more efficient
than gas
01

Pulls in free heat

A quiet top-mounted fan draws in surrounding air — even cool garage air at 50°F is full of usable heat.

02

Compresses it hotter

The compressor concentrates that captured heat, driving its temperature past 160°F — far hotter than the air it came from.

03

Heats your water

Hot refrigerant flows through the condenser coil wrapped around the tank, releasing its heat into the water.

04

Backup only when needed

Because it moves heat instead of burning gas, electric elements only add a boost during heavy demand — zero emissions, rebate-ready.

Why San Jose Homes Need Specialized Plumbing

San Jose plumbing isn't one-size-fits-all. Our crews know the housing stock, the water, and the city's permit rules block by block.

01

Aging Housing Stock

Historic neighborhoods like Willow Glen, Naglee Park, and the Rose Garden are full of 1920s–40s homes with galvanized supply lines and cast-iron drains. We specialize in repiping and trenchless sewer work that protects mature landscaping.

02

Hard Water From the Valley

San Jose Water and Valley Water deliver notably hard water across the Santa Clara Valley. Untreated, it scales up tankless heat exchangers and shortens fixture life — so we pair installs with descaling service and softeners.

03

City Permits & CA Code

Water heater replacements in San Jose require a city permit and code-compliant seismic strapping, expansion tanks, and drip legs. We pull the permit and handle inspection so your job passes the first time.

What San Jose Homeowners Say

Umed and Saba with a San Jose customer after a bathroom sink repair

"Wow. Best home service I've ever experienced. Umed examined the leak and gave a very competitive estimate — he and his brother Saba came the next day with the right parts and got straight to work. Backed by a one-year warranty."

"Our 20-year-old gas water heater had a leak, so we used the San Jose Clean Energy incentive to switch to a heat pump. Umed was first to respond, quick to answer questions, and got the city inspection approved ahead of schedule."

Ken C. — San Jose · Verified Yelp Review

FAQ

San Jose Plumbing FAQ

Do I need a permit for water heater replacement in San Jose?
Yes. The City of San Jose requires a plumbing permit for water heater replacement, along with code-compliant seismic strapping, an expansion tank, and proper venting. Peak Home Service pulls the permit and schedules inspection as part of the job, so everything passes the first time.
How hard is the water in San Jose, and does it affect tankless heaters?
San Jose's water is moderately to very hard across most of the Santa Clara Valley. Hard water deposits scale inside tankless heat exchangers, which lowers efficiency and can shorten the unit's life. We recommend an annual descaling flush and, in many homes, a softener or scale-inhibitor installed on the cold-water inlet.
What does emergency plumbing cost in San Jose?
Emergency pricing depends on the issue, but we always give upfront, flat-rate pricing before any work starts — no surprise hourly charges. Call (669) 336-6955 and we'll dispatch a licensed San Jose plumber, diagnose the problem, and quote the fix on the spot.
How fast can you get to my San Jose home?
We offer same-day service across San Jose and 24/7 emergency dispatch. For most neighborhoods — Willow Glen, Berryessa, Evergreen, Almaden, and downtown — we can usually have a technician at your door within a couple of hours.
Do I have to replace my gas water heater in 2027?
No. California's BAAQMD Rule 9-6 is a point-of-sale rule — you can keep and repair your existing gas water heater as long as it works. But once it fails and needs replacing after January 1, 2027, the only legal option in San Jose is a zero-emission heat pump water heater. Switching before the deadline means you pick the timing and capture today's rebates instead of facing an emergency electrical upgrade.
Why does my drain keep clogging in San Jose?
Most recurring clogs trace to four causes: grease and food scraps in kitchen lines, hair and soap scum in bathroom drains, hard-water mineral scale narrowing older Santa Clara Valley pipes, and tree roots intruding into the cast-iron and clay sewer laterals common in San Jose's older neighborhoods. Snaking clears the symptom; we camera-scope the line to find the real cause, then hydro-jet or trenchless-repair so it stops coming back.
