Washington County Oregon Trade, Solar, Plumbing, and Right-of-Way Permit Guide

Washington County uses BDAS for electrical, plumbing, mechanical, and prescriptive solar permits, while public right-of-way work uses a separate public permitting portal.

Permit takeaway

Washington County's BDAS portal accepts electrical, plumbing, mechanical, prescriptive solar, and NFPA 13 sprinkler affidavit permits that do not require plan review.

Zoning and placement

Right-of-way work such as sidewalks, driveways, accesses, sewer lines, storm drains, and private water lines requires a right-of-way permit to protect public infrastructure.

Building and trade review

Plumbing permits are required for water heater replacement, underground piping, concealed piping changes, new plumbing installations, and plumbing relocation in remodels or additions.

Call before applying when

Call before applying if the work is in the public right-of-way, involves concealed plumbing, requires plan review, includes prescriptive solar eligibility questions, or combines multiple trades with building work.
