Commercial Building Permit and Development-Compliance Review (Unincorporated Washington County)

The county's Building Services page states that 'Washington County (as per ORS Chapter 455 and 478 and the Home Rule Charter) regulates nuisances, construction, abatement of nuisances and administration of standards', including enforcing the State of Oregon building codes, and its Building Services FAQ states that its answers 'apply to locations within unincorporated Washington County. For questions concerning properties located within cities, visit the relevant city websites.' The fees are from the Building Services FY 26-27 Fee Schedule (effective 7/1/2026), part of the FY 2026-27 Adopted Fee Schedule (Resolution and Order No. 26-57). A commercial building permit is valued on the higher of the ICC Building Valuation Data figure for the occupancy and construction type or the applicant's stated value, and costs $236 for the first $2,000 of valuation, with further per-$1,000 charges above that as set out in the FY 2026-27 fee schedule, plus the applicable state surcharge and the seismic site surcharge the schedule shows as currently 1% (ORS 455.447(3)). Plan review is 65% of the building permit fee (commercial mechanical plan review 25%), fire and life safety review 40%, inspections $236 per hour, and a commercial temporary certificate of occupancy $505. Current Planning's development-compliance review of a building permit is $137 under $75,000 of value, $960 for $75,000 to $500,000 and $1,424 over $500,000.
