Benton County, WA Sidewalk & Pedestrian Rules: Encroachment Permits (2026)

052, carried through Ord. 272 (1996), Ord. 303 (1997) and Ord. 602 (2018), makes permission to construct a road approach a precondition of county building permitting: when required, the applicant must obtain a road encroachment permit from the jurisdiction in control of the road or highway providing access to the parcel before the Benton County Building Department will issue a building or placement permit. 053(b) closes the loop at the back end of construction, requiring that the road encroachment be completed to the controlling jurisdiction's standards and that a final encroachment permit be issued before the county will issue a Certificate of Occupancy.

018 likewise lists 'Conditional Approval to Construct Road Approach on Public Road' as a required element whenever a road approach is needed to reach the parcel, meaning the applicant must show at least conditional encroachment approval before the building permit itself is complete. Because Benton County roads, state highways and city streets all fall under different road authorities depending on location, the applicant must identify which entity, the county Public Works department, WSDOT, or a city, actually controls the specific road before applying, since that agency, not the Benton County Building Department, issues the encroachment permit itself.
