Illinois State Prevailing Wage Law

State law: Yes — applies to qualifying state-funded projects
Threshold: Generally any public works
Enforcing agency: Illinois Department of Labor (IDOL)

Illinois requires prevailing wages on most public works projects regardless of dollar amount under the Prevailing Wage Act (820 ILCS 130). IDOL publishes monthly per-county rates by craft. Certified payroll reports must be submitted electronically to IDOL through the state portal.

Verify before relying on this: state prevailing-wage laws change. The summary above is a general reference compiled from publicly available state-law materials and is not legal advice. Confirm the current status with the cited state agency or a qualified attorney before bidding or paying workers under it.
