Why Arizona Is Different
Arizona operates its own OSHA-approved State Plan, administered by ADOSH (Industrial Commission of Arizona) under Arizona Revised Statutes Title 23, Chapter 2, Article 12. This means Arizona doesn't just follow federal OSHA — it sets and enforces its own workplace safety standards that can be stricter than federal minimums.
For General Contractors operating in Arizona, this means you need to meet Arizona-specific requirements, not just the federal baseline. ADOSH (Industrial Commission of Arizona) conducts its own inspections, issues its own citations, and sets its own penalty amounts.
Arizona requires 1 additional program beyond federal OSHA that directly affect General Contractors.
Penalty Snapshot
- Serious violation: up to $16,550 per citation

- ARS §23-418 ties penalty amounts to federal OSHA maximums per Federal Civil Penalties Inflation Adjustment Act.
Top Hazards for General Contractors
General contractors face unique multi-employer liability — OSHA can cite the GC as the controlling employer even when a subcontractor created the hazard.
- Falls from elevation (29 CFR 1926.501) — Falls are the #1 killer in construction. GCs are responsible for fall protection on multi-employer sites even for subcontractor crews working at heights.
- Struck-by objects (29 CFR 1926.602) — Falling tools, swinging loads, and vehicle strikes. GCs managing multiple trades on-site face compounded struck-by risk from overlapping operations.
- Trenching and excavation collapse (29 CFR 1926.652) — Trench collapses kill fast. GCs must ensure protective systems (sloping, shoring, shielding) are in place before any worker enters an excavation over 5 feet.
- Scaffolding hazards (29 CFR 1926.451) — Improperly erected scaffolds account for thousands of citations annually. GCs must verify scaffold competency and inspection schedules on their sites.
- Multi-employer site coordination (Multi-employer citation policy) — As the controlling employer, GCs can be cited for hazards created by subcontractors. Site safety coordination and daily walkthroughs are essential.
Most-cited violations for General Contractors: Fall protection (1926.501), scaffolding (1926.451), ladders (1926.1053), hazard communication (1910.1200), and excavation/trenching (1926.652)

Key Regulatory Differences from Federal OSHA
- Fall Protection Threshold: 6 feet — federal standard applies. Arizona's 15-foot residential exception (SB 1441, 2012) was repealed July 2019. Standard 6-foot federal requirement now applies statewide.
- Heat Standard Status: No formal ADOSH written heat standard as of March 2026. Enforced via OSHA General Duty Clause. Phoenix ordinance requires written plan for City contract work. Task Force guidelines expected before summer 2026 per EO 2025-09.
- Tribal Land: Work on Indian reservations falls under FEDERAL OSHA jurisdiction, not ADOSH. Must include disclaimer in programs.
- Copper Smelter Mines: Copper smelters and mine-adjacent batch plants under MSHA/federal jurisdiction, not ADOSH.
- Injury Reporting: Same timeline as federal (8hr fatality, 24hr hospitalization/amputation/eye loss) — reports go to ADOSH.
- Posting: Arizona ADOSH workplace safety poster required alongside federal poster
