Tucson, AZ Sidewalk & Pedestrian Rules: Obstruction Rules (2026)

Pima County prohibits obstructions on public sidewalks and pedestrian facilities within county rights-of-way. Common obstruction issues include trash containers left on sidewalks after collection days, vehicles parked across sidewalks (driveways blocking pedestrian paths), overgrown vegetation from adjacent properties, construction materials and equipment without encroachment permits, and sandwich board signs or merchandise displays. Pima County DOT addresses obstruction complaints through its right-of-way management program. Property owners with vegetation encroaching into public sidewalks may receive notice to trim to maintain minimum clearance (typically 7 feet vertical, full sidewalk width horizontal). Construction projects requiring temporary sidewalk closures need PCDOT encroachment permits with pedestrian detour plans. ADA requirements (28 CFR Part 35) mandate that public sidewalks remain accessible, and Pima County must address reported barriers under its ADA transition plan. Utility companies performing work on county rights-of-way must restore sidewalks to pre-work condition. Desert landscaping that extends gravel or decorative rock onto public sidewalks is a common Pima County issue addressed through right-of-way enforcement.
