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

Renton treats any unauthorized structure, object or activity placed on a public sidewalk or other right-of-way as an "encroachment" under RMC 9-17-1, and the policy is blunt: unauthorized use of public lands "will be deemed trespassing regardless of when the property was initially encroached upon." RMC 9-17-2 defines "Public Lands" to expressly include "sidewalks" alongside parks, fire stations and libraries, and defines "Encroachment" broadly to cover "clearing, grading, gardening, landscaping, installing structures, constructing, storing, placing, dumping, maintaining, cutting, overhanging, excavating, parking, diverting... and limiting access onto" public property, so a planter, fence, parked trailer or stored materials blocking a sidewalk all qualify.

Enforcement starts informally: Code Compliance staff first try to contact the encroaching owner in person and work out voluntary removal under RMC 9-17-3(A)(1). If that fails, the City mails a written Encroachment Violation Notice giving thirty (30) days to remove the encroachment and restore the area, per RMC 9-17-3(A)(3). A second, "Return Receipt Requested" notice with another thirty-day deadline follows under RMC 9-17-3(B)(1) if the first is ignored; after that, the City may remove the encroachment itself and bill the property owner for the cost under RMC 9-17-3(B)(2) and RMC 9-17-6, with unpaid costs becoming a lien on the property. RMC 9-17-7 also charges the encroaching party for the value of the City's property used, at one percent (1%) of fair market value per month or fifty dollars ($50.00) per month, whichever is greater. Property owners may appeal an Encroachment Violation Notice in writing to the Parks and Recreation Administrator within thirty (30) days under RMC 9-17-4.
