What federal OSHA is targeting in Illinois
Illinois has no state OSHA plan for private-sector work, so there is no state rule to read. What differs here is which hazards federal OSHA schedules inspections for, as set out in published emphasis directives.
Local Emphasis Program for Building Renovation/Rehabilitation and Demolition
CPL 04-05-2302 · Chicago Regional Office · effective October 1, 2023
“This Notice applies to the Appleton, Naperville, Chicago North, Chicago South, Cincinnati, Cleveland, Columbus, Madison, Milwaukee, Peoria, Fairview Heights and Toledo Area Offices.”
Reconstruction, renovation, rehabilitation and demolition are scheduled for inspection through twelve named area offices covering Illinois, Ohio and Wisconsin. Renovation work is where fall protection, scaffolds and ladders tend to be improvised, and the program exists because that is where the region's inspectors expect to find them improvised.
Local Emphasis Program for High Rise Building Construction Inspections
CPL 04-05-2303 · Chicago Regional Office · effective October 1, 2023
“This Notice applies to the Chicago South Area Office and Chicago North Area Office.”
High-rise construction has a programmed-inspection program of its own, and its reach is narrow and specific: the Chicago South and Chicago North area offices. The same work outside those two offices' jurisdiction is not inside this program.
Falls and work deaths in Illinois, 2024
Illinois recorded 156 fatal work injuries in 2024, up from 145 in 2023. Falls, slips and trips caused 30 of them (19%). Construction accounted for 26, 11 of them from falls, slips and trips.

U.S. Department of Labor / OSHA news release, September 16, 2019How Illinois Enforces 29 CFR 1926.451
Illinois operates an OSHA-approved state plan (Illinois OSHA (IL OSHA)), but it covers only state and local government employees. Private-sector construction employers in Illinois are inspected by federal OSHA, which enforces 29 CFR 1926.451 directly using the federal penalty maximums. So if you run a private construction company in Illinois, Scaffolding citations come from a federal Department of Labor compliance officer, not Illinois OSHA (IL OSHA).
In Illinois, the FY2025 citations under 29 CFR 1926.451 went most often to Masonry Contractors (94) and Roofing Contractors (36). A single inspection can produce several per-instance citations. Recurring self-audits against 29 CFR 1926.451, before an officer arrives, are the most reliable defense.
For a private-sector jobsite in Illinois, HazComFast shows that federal OSHA has jurisdiction, because the state plan covers public employers only. Start free
