Summary

Portland requires a permit or minor label for nearly all plumbing work, from new water and sewer systems to rainwater harvesting and fixture removal.

a permit, or minor label as outlined in Section 25.04.040, must be obtained for the installation, construction, alteration, or repair of any plumbing or sewage system, fire hose valve, water supply system, water supply well, rainwater harvesting system, sewage holding tank, fire hose cabinet, or the installing of any device if the device requires either water supply, or waste connection to drainage system or both; for capping of a sewer where a building has been demolished or moved; and for removing plumbing fixtures and sealing openings.
