When you need a Water Heater permit in Sacramento
Same-for-same water heater replacement requires a plumbing permit. The new unit must meet current code including T&P valve (IRC P2803), discharge pipe (P2804.6.1), drain pan where required (P2801.6), and expansion tank if the home has a closed system (P2903.4). California, Washington, and most Oregon counties require seismic strapping, two straps minimum (upper third and lower third of the tank).
Converting from a tank to a tankless gas water heater requires plumbing AND gas permits. Tankless units demand 150,000-199,000 BTU/hr at full capacity, about 4-5x a tank unit's demand. Existing gas lines are typically undersized and must be upgraded. New direct-vent or power-vent systems are required; existing B-vent cannot be reused.
Installing a heat pump water heater requires plumbing AND electrical permits. HPWHs need a dedicated 240V/30A circuit, sufficient air volume (450-700 cubic feet minimum per manufacturer specs), and condensate drainage. Note: the federal 25C tax credit for HPWHs expired December 31, 2025, state and utility rebates may still apply.
Relocating a water heater to a new location requires a full permit stack: plumbing (new water connections), gas (if gas-fired, new piping and venting), and electrical (for electric or heat pump units). This is significantly more complex than a same-location replacement and typically costs $1,500-$3,500 in additional plumber labor.
