Water Heater · Clark County, Washington
Permit required
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 Clark County Building Department before work begins.

Replacing a water heater requires a safety inspection to prevent gas leaks or explosions.
As one of the more densely populated areas in Washington, Clark County (around 516,959 residents) tends to see higher application volumes at its building department, so it helps to prepare your documentation in advance.
Code Compliance & Inspections
Under Washington seismic provisions, your installation will be reviewed for compliance with the anchoring and bracing requirements of the Washington State Building Code.
Seismic note: In earthquake-prone states like Washington, heavy equipment such as water heaters and HVAC units is often required to be secured with seismic strapping to pass final inspection. Confirm the current requirement with Clark County's inspector.
Concurrent Permits & HOAs
For Clark County residents, we highly recommend reviewing your neighborhood HOA covenants before paying any municipal fees. Often, homeowners associations maintain stricter rules regarding materials and dimensions for your Water Heater than the county itself.
Zoning & Cost Factors
Washington operates under the Growth Management Act (GMA), requiring fast-growing counties to adopt comprehensive plans to manage density and protect critical areas. Fortunately, Washington maintains relatively builder-friendly regulations, keeping base permit fees competitive.
