Water Heater · Clackamas County, Oregon
Permit required
In Oregon, a Water Heater requires a plumbing permit.
Oregon requires a permit for water heater replacement. Seismic strapping (upper and lower third of the tank) is required in the western, higher-seismic part of the state but NOT in 15 eastern counties (Baker, Crook, Deschutes, Gilliam, Grant, Harney, Jefferson, Malheur, Morrow, Sherman, Umatilla, Union, Wallowa, Wasco, Wheeler). Inspectors check the T&P discharge and venting. Plans are reviewed under the OR / Clackamas County code; apply through Clackamas County Building Permits before work begins.

Replacing a water heater requires a safety inspection to prevent gas leaks or explosions.
With a population of around 423,975 residents, Clackamas County generally runs a more streamlined permitting process than major urban hubs.
Code Compliance & Inspections
Under Oregon seismic provisions, your installation will be reviewed for compliance with the anchoring and bracing requirements of the Oregon Structural Specialty Code.
Seismic note: In earthquake-prone states like Oregon, 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 Clackamas County's inspector.
Concurrent Permits & HOAs
For Clackamas 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
Oregon is famous for its statewide land-use planning program, which legally mandates "Urban Growth Boundaries" to prevent sprawl and protect farm and forest lands. Fortunately, Oregon maintains relatively builder-friendly regulations, keeping base permit fees competitive.
