Denver, CO Building Safety: Scaffold & Sidewalk Shed (2026)

Scaffolding in Denver is regulated by the Denver Building Code (administered by Community Planning and Development) and the Department of Transportation and Infrastructure (DOTI) for structures in the public right-of-way. A right-of-way occupancy permit from DOTI is required for any scaffolding that extends over or occupies a public sidewalk, street, or alley. The 2025 Denver Building Code incorporates IBC requirements for scaffolding design and safety. Colorado follows federal OSHA scaffolding standards (29 CFR 1926 Subpart L) enforced through the state's OSHA consultation program. All scaffolds must be erected, modified, and dismantled under the supervision of a competent person. Fall protection is required on scaffold platforms above 10 feet, including guardrails with toeboards or personal fall arrest systems. Scaffolding must be designed to support at least four times the intended load. Regular inspections are required before each work shift and after weather events that could affect structural integrity. Pedestrian protection (sidewalk sheds or covered walkways) must be provided when scaffolding is erected above public sidewalks. Denver's 2024 Street Use Fee Schedule establishes fees for scaffolding permits occupying the right-of-way.
