Santa Ana, CA Building Safety: Scaffold & Sidewalk Shed (2026)

California Labor Code Sec. 7150-7158 establishes the legal framework for scaffold safety on all construction, repair, and painting projects in Santa Ana. Under Sec. 7151, any employer who knowingly or negligently furnishes unsafe scaffolding is guilty of a misdemeanor. Cal/OSHA Construction Safety Orders (Title 8, Sec. 1637-1670) provide detailed technical requirements: scaffolds must be designed to support at least four times the maximum intended working load. Light-duty scaffolds support 25 pounds per square foot, medium-duty 50 pounds, and heavy-duty 75 pounds. Scaffolds are required for all work that cannot be safely performed from permanent construction at least 20 inches wide. Guardrails must be installed on all open sides of scaffolds more than 7.5 feet above the ground. Workers must have safe means of access to scaffold platforms, and scaffold planking must extend over the end supports by at least 6 inches but no more than 12 inches. All scaffolds must be inspected by a competent person before each work shift. The Santa Ana Building Safety Division may require scaffold plans for projects requiring building permits, particularly in the dense downtown area where public sidewalk protection is needed.
