Do you need a permit for Water Heater in Benton County?
In Washington, a Water Heater requires a plumbing permit.
Replacing a water heater requires a plumbing permit and inspection, including a same-for-same swap. Washington enforces seismic strapping under its UPC amendments, and the T&P valve, drain pan, and expansion tank are checked. Fuel changes or tankless conversions add gas or electrical permits. Plans are reviewed under the Statewide code (IRC 2021); apply through Benton County Building Department before work begins.
