Seattle Encroachment Permit for Street Work

Transportation Washington 3 Minutes Read · published February 07, 2026 Flag of Washington

Seattle, Washington requires permits for most work that occupies or alters the public right-of-way. An encroachment permit (also called a street-use or right-of-way permit) authorizes construction, long-term equipment, scaffolding, or other uses that extend into a sidewalk, curb lane, planting strip or other street area. Before scheduling crews, confirm permit requirements, traffic-control plans and restoration standards with the responsible city department to avoid stop-work orders or removal at your expense. For city guidance on street and right-of-way permits see the Seattle Department of Transportation resources[1].

Overview

An encroachment permit is required whenever private work will temporarily or permanently occupy public street space, including curb cuts, scaffolding, utility excavations, material storage, or hoisting operations. Permits govern insurance, bonding, approved plans, working hours, and traffic control. Typical applicants are contractors, utility companies, and property owners. Determine the required permit type early in project planning and include traffic control and restoration details in your submission.

Apply early—processing and required traffic control reviews can add days to your schedule.

Penalties & Enforcement

Specific monetary fines for unauthorised encroachments are not specified on the cited page; the city also uses stop-work orders, removal of the encroachment at the owner/applicant expense, and civil enforcement when necessary.
