Multnomah County Plumbing Permit Requirements
Multnomah County enforces the Oregon Plumbing Specialty Code (OPSC) in unincorporated areas of the county to protect public health, safety, and general welfare. A permit is generally required for any new plumbing installation, extension, alteration, or replacement of a plumbing system. This includes connecting fixtures, water heaters, backflow prevention assemblies, and gas piping.
For properties in unincorporated areas, Multnomah County handles permitting directly. However, for structural building permits, these are routed to the City of Portland, City of Gresham, or City of Troutdale, depending on the specific service area. Zoning and land use permits, as well as permits for floodplain, geologic hazards, erosion and sediment control, and transportation, are handled by Multnomah County Land Use Planning.

The BCD is authorized by Oregon Revised Statutes (ORS) Chapter 447 and Chapter 693 to establish statewide plumbing standards and manage the licensing program for plumbing professionals. The State Plumbing Board assists the BCD by providing expertise, overseeing licensing, and ensuring that plumbing work meets minimum safety standards through the code adoption and review process.
