Welcome to Washington County Building Services. We are a full-service building permit office providing permitting, plan review and inspections for all phases of construction on commercial and residential properties in unincorporated Washington County and inside the city limits of Banks, Gaston and North Plains.
In addition, we provide electrical permitting, plan review and inspections for the cities of Cornelius, Durham, Forest Grove, Sherwood and Tualatin.
Unsure in which jurisdiction your property resides?
To learn in which jurisdiction your home or business is located, input your address into the Oregon E-Permitting website. If your property is located in another jurisdiction, contact that building department to get answers to the questions you need. You can also find a listing of building departments throughout the State of Oregon on the ThinkPermit.com website.
Any changes to or on your existing property, such as additions, garage conversions, decks, sheds and fences, need to be approved through the Current Planning and Development Assistance section. In person assistance is available Monday through Thursday 8:00 a.m. - 4:00 p.m. during walk-in lobby hours. Phone assistance 503-846-3470 is available Monday through Friday 8:00 a.m. - 5:00 p.m. You can also e-mail your questions to firstname.lastname@example.org.
Considering a voluntary seismic upgrade for your existing home?
Many homes built before the 1980s were built using older construction techniques that are inadequate for the forces we now know earthquakes can cause. You can find more information at our Seismic Strengthening website.
