Water Heater · Marion County, Oregon
Permit required
In Oregon, a Water Heater requires a plumbing permit.
Replacing a water heater requires a plumbing permit and inspection, including a same-for-same swap; most Oregon counties also require seismic strapping. Switching fuel type, relocating, or going tankless adds gas or electrical permits. Plans are reviewed under the Statewide code (IRC 2021); apply through Marion County Public Works before work begins.

With a growing population of around 349,244 residents, Marion County maintains a relatively streamlined permitting process compared to major urban hubs. Processing typically takes 1 to 3 weeks.
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.
