A few things we run into on San Jose calls again and again.
Neighborhoods like Willow Glen, Naglee Park and the Rose Garden have many early-20th-century homes, where galvanized supply lines and cast-iron or clay sewer laterals are common. That's where repiping and a sewer camera inspection earn their keep.
Much of San Jose gets moderately hard to hard water, and scale builds up in water heaters, tankless heat exchangers and fixtures. We test hardness for free at a water treatment consultation and recommend a softener or filtration only when it makes sense.
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.
BAAQMD has adopted zero-NOx standards for certain new water heaters, and additional amendments are currently under consideration. Requirements and effective dates vary by equipment type and may change. PEAK Home Service can help San Jose homeowners compare gas, tankless and heat-pump options based on the rules, rebates and equipment available at the time of installation.
Per BAAQMD, a working water heater can stay in service until it burns out or needs replacement. The rule applies when new equipment is sold or installed.
Requirements are based on the water heater's BTU rating and date of manufacture — not on your home's age or a property sale.
The BAAQMD Board is scheduled to consider Rule 9-6 amendments on November 4, 2026. If approved, they would add some exemptions and extend the compliance date.
We'll explain which gas, tankless and heat-pump options fit your home, space and electrical setup under the rules in effect when you install.
Regulatory information last reviewed: October 2026. Verify current requirements with BAAQMD before installation. Rebate amounts, eligibility and funding are set by each program and change often — we check current programs with you before any work begins.
