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

The core obstruction standard sits in IMC 12.05.080(F), which governs any sidewalk use permitted under chapter 12.05. Subsection F(1) reserves a minimum of four feet of sidewalk width for pedestrian use and requires that area to stay free and clear of all obstructions at all times. Subsection F(2) requires placement consistent with Americans with Disabilities Act standards and prohibits obstructing vehicular traffic or parking, vehicular traffic sight distance triangles, or the use of any crosswalk, wheelchair ramp or bus zone. Subsection F(3) bars operating the use in a way that restricts access to the abutting property, prevents pedestrian use of the sidewalk, creates a nuisance or hazard to public health, safety or welfare, or obstructs fire, police or sanitation vehicles. Subsection F(4) requires pedestrian entrances to buildings to be a minimum of 48 inches wide, in accordance with ICC A117.1 Section 403.5.1, and kept clear at all times. Subsection F(5) bars placement that impedes people entering or exiting parked vehicles.

Other subsections tighten the rule. The permittee must ensure the use does not encroach into the roadway or push pedestrians out of the designated pedestrian travel zone (G), and may operate only in the portion of sidewalk and the days and hours identified on the permit (H). A sidewalk cafe must not be secured to any public amenity (E), fixtures such as railings cannot be bolted or affixed to the public place unless the City authorizes it (C), and only materials used for daily operation can sit on the sidewalk (D). The Public Works Director can deny an application under 12.05.070 if the use does not allow pedestrian travel access without limitations.

A separate duty applies to ordinary owners. IMC 12.08.030 makes the owner of property abutting a public sidewalk responsible for keeping it safe and free of any and all obstructions or defects.
