Shed permit rules in Washington County, OR — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Accessory structures in unincorporated Washington County must meet setback requirements from property lines. Setback waivers are not permitted. Each land use district has unique setback requirements under CDC 418. Sheds under 200 sq ft are typically exempt from building permits under Oregon code.
The Community Development Code requires all accessory structures (play structures, trellises, sheds, etc.) to meet setbacks. Setbacks vary by zone and lot configuration. Building permits may be required for larger structures. Resource overlays and prior conditions of approval may affect allowances on specific properties.
Unpermitted structure: retroactive permit with penalty. Non-compliant setback: modification or removal.
