Water Heater Repair and Replacement in Saratoga, CA

A Homeowner’s Guide to Water Heater Repair and Replacement in Saratoga

Permits and inspections

Saratoga’s Community Development Department (408-868-1240) requires a permit for every water heater installation, replacements included. A replacement-only permit may be issued over the counter, and applications and inspection requests run through eTRAKiT. The City lists express online water heater permits as coming soon.

The heater must follow the manufacturer’s installation instructions and the current California Plumbing Code and Mechanical Code. The inspector then works from the City’s Water Heater Replacement handout.

The City’s inspection checklist

The handout’s 12 items, each tied to a code section, cover more than most homeowners expect:

• Elevation: in a garage, burners and ignition 18 inches above the floor, unless the unit is listed as flammable-vapor-ignition resistant.
• Seismic bracing: two straps, one in each outer third, the lower one at least 4 inches above the controls, and a third strap over 52 gallons. Straps wrap completely around the tank and fasten to framing with a ¼ by 3 inch lag bolt and washer. Plumber’s tape isn’t approved.
• Venting: Type B, BW, L or another listed vent through ceilings, attics, floors and roofs; generally vertical, with offsets of 45° or less; connectors sloped up ¼ inch per foot.
• Clearances: 6 inches from combustibles for single-wall connector, 1 inch for double-wall; in an attic, a metal sleeve 6 inches above the insulation.
• Termination: at least 12 inches above the roof with a cap, 5 feet of total vent height, and 4 feet from any building opening.
• Relief line: ¾-inch copper or galvanized pipe, full size, run outside and ending 6 to 24 inches above the ground, pointing down.
• Gas: a shutoff valve next to the heater, ahead of a flexible connector no longer than 3 feet and the sediment trap.
• Finish items: combustion air, a metal collar where the vent passes a ceiling, and bonding of metal water and gas piping.

State law, Health and Safety Code § 19211, requires the bracing on new, replacement and existing heaters.

Hard water in grains per gallon

San Jose Water’s 2025 report gives hardness for Saratoga’s three possible sources in grains per gallon as well as ppm: Compare other cities in our South Bay water hardness table.

• Groundwater: 16.8 grains average, from 10.2 to 26.4.
• Mountain surface water: 9 grains.
• Valley Water: 5.8 grains.

Its service map shows which source mainly serves an area. On groundwater, plan on flushing a tank and descaling a tankless unit more often. See water heater services.

Electric readiness in remodels

Article 16-51 of the City Code (Ordinance 414, November 5, 2025) adds an electric readiness reach code for single-family alterations and additions. For water heaters:

• Framing within 3 feet of a gas or propane heater removed or replaced: leave a 2.5 by 2.5 by 7 foot space for a future heat pump water heater, with a condensate drain no more than 2 inches above the heater’s base, or a pump outlet.
• Circuits within 3 feet of the gas heater, or 10 feet of that future space, when the work needs an electrical permit: a 240-volt-ready circuit or a labeled pathway for one.

Repairs, and projects that need no electrical permit apart from this rule, are exempt. A plain replacement isn’t covered. The City still recommends adding an outlet near the heater ahead of time.

Heat pump water heaters: SVCE and the Air District

Silicon Valley Clean Energy’s Home Rebates cover a heat pump water heater of 40 gallons or more replacing gas or electric resistance. The unit needs a UEF of 3.3 or higher (120-volt and split systems excepted), a NEEA Tier 3 rating and a thermostatic mixing valve; tankless units don’t qualify. Reserve first; approvals hold for 120 days, and proof of permit is required. SVCE’s Emergency Water Heater Replacement program swaps failed gas units through partner contractors. See heat pump water heaters and SVCE heat pump rebates.

The City’s Electrification page notes that the Air District’s 2023 rules phase out standard gas water heaters as early as 2027. As adopted, Rule 9-6 requires zero NOx from gas water heaters under 75,000 BTU/hr manufactured after January 1, 2027; the Board votes November 4, 2026 on moving that to 2028. See Bay Area zero-NOx rules.
