Auburn, WA Sidewalk & Pedestrian Rules: Obstruction Rules (2026)

King County Code Title 14 regulates the use and obstruction of public rights of way, which includes sidewalks in unincorporated areas. Property owners and occupants are prohibited from placing obstructions on sidewalks that interfere with pedestrian travel, including ADA-required 4-foot clear path. Common obstructions include: parked vehicles across sidewalks, overhanging vegetation (branches and shrubs) below 8 feet over sidewalks or 14 feet over roadways, construction debris and materials, merchandise displays, dumpsters, portable signs, and temporary storage. Use of the right of way for any obstruction beyond normal pedestrian and vehicle travel generally requires a right of way use permit from the King County Road Services Division. Temporary obstructions for construction or moving typically require a short-term permit. Residents must trim overhanging vegetation to maintain clearance; the county can issue a notice and, after noncompliance, trim at the owners cost. Blocking a sidewalk for commercial purposes (pop-up retail, food vendors, display signs) without a permit is a code violation. In winter, while Washington State has no statewide snow removal law, King County encourages but does not mandate sidewalk snow clearing in unincorporated areas. Complaints can be filed through King County Road Services.
