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.

Oregon Plumbing Codes and Legislation

The state of Oregon regulates plumbing installations, repairs, and alterations through the Oregon Plumbing Specialty Code (OPSC). The current edition is the 2023 OPSC, which became effective on October 1, 2023. This code is based on the 2021 edition of the Uniform Plumbing Code (UPC), published by the International Association of Plumbing and Mechanical Officials (IAPMO), and incorporates specific amendments tailored to Oregon's local needs, climate, and building standards.

Regulatory Agencies and Oversight

The primary state agency responsible for the adoption, administration, and enforcement of plumbing codes in Oregon is the Building Codes Division (BCD), which operates under the Oregon Department of Consumer and Business Services (DCBS). 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.
