Cal-Nev-Ari Building Safety: Scaffold & Sidewalk Shed Rules (2026)

Scaffold operations on unincorporated Clark County job sites are regulated by Nevada OSHA (NV-OSHA) under NAC 618 adopting federal 29 CFR 1926 Subpart L. Scaffolds more than 4 feet above lower levels require guardrails, midrails, and toeboards on all open sides, or a fall-protection system including personal fall arrest. Scaffold erection, alteration, and dismantling must be supervised by a competent person. Inspections by a competent person must occur before each work shift. Capacity must support at least 4 times intended load; suspension scaffolds 6 times. Strip construction (Circa, Fontainebleau, Resorts World) has driven intensive scaffold use on projects over 1,000 feet, where wind loads become critical; Clark County summer afternoon dust devils and monsoon microbursts can exceed 60 mph, requiring tie-offs beyond standard spacing. Heat illness prevention under NRS 618.375 requires water, shade, and acclimatization during summer temperatures that regularly exceed 110 degrees F. Public-right-of-way scaffolds require encroachment permits from Clark County Public Works. Pedestrian-protection canopies must be provided for scaffolds over sidewalks.
