Local Project Overview
Demolition · Washington County, Oregon
Permit required
In Oregon, demolishing a structure requires a permit.
Demolishing a building, or any structure with utilities or a foundation, requires a demolition permit, plus utility disconnects and often an asbestos check before work begins. Very small accessory structures such as a shed under 200 sq ft with no utilities may be exempt; confirm locally. Plans are reviewed under the Statewide code (IRC 2021); apply through Washington County Building Services before work begins.

Whether you are tearing down an old shed, removing a swimming pool, or executing a full structural demolition, local regulations require strict oversight. Tearing down structures involves managing hazardous waste and shutting off municipal utilities, which is why pulling a permit is almost always a mandatory first step.
As one of the more densely populated areas in Oregon, Washington County (around 603,947 residents) tends to see higher application volumes at its building department, so it helps to prepare your documentation in advance.
Code Compliance & Inspections
Under Oregon seismic provisions, structural plans are reviewed for retrofitting and shear-wall integrity to comply with the Oregon Structural Specialty Code.
HOA & Historic District Approvals
In highly urbanized counties like Washington County, many properties are also subject to Homeowners Association (HOA) approval before a city permit can be applied for. If you live in a designated historic district, the local architectural committee may also have review authority over your Demolition.
Zoning & Cost Factors
Oregon is famous for its statewide land-use planning program, which legally mandates "Urban Growth Boundaries" to prevent sprawl and protect farm and forest lands. Fortunately, Oregon maintains relatively builder-friendly regulations, keeping base permit fees competitive.

Frequently Asked Questions
What are the specific penalties for unpermitted Demolition work in urban Washington County?
Building without authorization is considered a code violation. The local government can issue a Stop Work Order, forcing you to halt construction immediately. You may be subject to retroactive permit fees (often double the original cost), daily fines, or even a mandate to tear down the unpermitted work at your own expense.
Can a homeowner pull their own Demolition permit in Oregon?
Yes. Oregon generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the Oregon Structural Specialty Code.
How much does a Demolition permit cost in Washington County?
Permit fees vary by jurisdiction and by your project's valuation, so Washington County does not publish a single fixed figure. Confirm the exact fee with the local building department before applying.
