The following apply to locations within unincorporated Washington County. For questions concerning properties located within cities, visit the relevant city websites.


  • Accessory structures 
    • Accessory structures (play structure, trellis, shed, etc.) are required to meet setback requirements from property lines. Waivers are not permitted. Each land use district (zone) in the County has unique setback requirements. Building permits may be required for accessory structures. Contact Current Planning for details. 
  • Agricultural buildings 
    • Structures outside the Urban Growth Boundary (UGB) over 400 square feet and/or more than one story high require an Agricultural Building permit from Building Services. Use of these structures by the public or conversion of these structures to a residential-type use is prohibited. 
  • Construction noise outside of allowed hours 
  • Construction without a permit 
    • Land development and construction without required permits is a violation of both the CDC and the Building Code. Proper permitting ensures public health and safety is maintained. Building plan submittal and the issuance of required permits will be retroactively required as applicable. Contact Building Services for specific permitting requirements or Current Planning to report unpermitted work. 
  • Grading permits 
    • Grading permits are often required for digging and/or fill placement associated with any development activity or land use approval. Email Building Services or call 503-846-6733 before beginning any work. 


  • Oil spills in street/driveway 
  • Resource overlay zones 
    • Some properties are subject to regulations specific to natural resources and flood plain enhancement and protection. Regulations apply for developments proposed on properties subject to the 100-year Floodplain Overlay, Drainage Hazard Area Overlay and Significant Natural Resource Overlay. Contact Current Planning to determine if any overlays are applicable. 
  • Roosters and poultry 
    • Washington County does not regulate peacocks, roosters or the number of chickens. Structures over 51 square feet in size housing poultry need to be located at least 30 feet from any property line and at least 100 feet from any neighboring home. All structures must be a minimum of 3 feet from a property line and may be required to meet the (greater) district setbacks from all property lines. 
  • Tree removal 
    • Trees located in County-designated Significant Natural Resource (SNR) areas cannot be removed without land use review and approval. In other areas, tree removal is typically at the discretion of a property owner and does not require a permit. Contact Current Planning to determine if any regulations apply before removing trees. 

      The County does not regulate tree removal on private properties as long as the designation above does not apply. Neighboring property owners who disagree with tree maintenance/removal are eligible for free mediation services throughBeaverton Center for Mediation and Dialogue or Hillsboro Mediation Program
