Read GuideLocal Project Overview
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.
Given that Multnomah County has a densely packed population of 801,477 residents, the local building department frequently experiences high application volumes. Expect processing times of 4 to 8 weeks for standard residential projects.
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 Multnomah County, municipal bureaucracy is only the first step. You will almost certainly need written approval from your Homeowners Association (HOA) before applying for a city permit. Additionally, if you live in a designated historic district, the local architectural committee holds veto power 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.
Estimated municipal base fee: $128–$195
This is a planning estimate only — actual fees in Multnomah County depend on your project valuation. A typical breakdown looks roughly like:
- Application Fee: ~$45
- Plan Review Fee: ~$30

Always confirm exact fees with your local building department before applying.
