Bellevue, WA Building Safety: Scaffold & Sidewalk Shed (2026)

Scaffolding in Bellevue must meet Washington Division of Occupational Safety and Health (DOSH) standards in WAC 296-874, which mirror federal OSHA requirements. Scaffolds above 10 feet require guardrails, toeboards, and fall-arrest systems depending on the type, and must be designed to support at least four times the intended load. Erecting, altering, or dismantling scaffold must be supervised by a competent person, and employees using scaffolds must receive documented training. For projects adjacent to public sidewalks or streets, Bellevue requires a Right-of-Way Use Permit from the Transportation Department when scaffolding, hoists, or protected walkways encroach into the public way. Covered pedestrian walkways may be required for multi-story work to protect passers-by from falling tools and debris. Sidewalk sheds must provide continuous lighted clearance and comply with ADA access. Residential DIY scaffolding around a homeowner's own property does not generally need a permit unless it occupies the right-of-way. Complaints about unsafe scaffolding near workers typically go to Washington DOSH; unsafe public-way conditions go to Bellevue Transportation or Police.
