Do I need a permit for swimming pool or spa in Unincorporated Multnomah County?

Permit required

Yes. In Oregon, swimming pool or spa generally requires a permit, and Unincorporated Multnomah County is no exception.

Barriers for residential swimming pools must comply with Section 305 of the International Swimming Pool and Spa Code (ORSC R328.1), and a fence serving as a pool barrier requires a building permit statewide, including around an exempt prefabricated pool. The design and construction of an in-ground pool itself is exempt from a building permit unless the municipality adopts an ordinance requiring one (ORSC R101.2.2 item 7); above-grade and on-ground pools are exempt (R105.2 item 4). Pool pump, lighting, and bonding wiring needs an electrical permit and inspection under the Oregon Electrical Specialty Code.
