Prevailing Wage Act

Requires contractor and subcontractor to pay laborers, workers, and mechanics employed on public works projects, no less than the general prevailing rate of wages (consisting of hourly cash wages plus fringe benefits) for work ​of similar character in the locality where the work is performed.

Violators must pay workers the difference between the wage paid and the prevailing wage, and are subject to penalties and punitive damages. A contractor or subcontractor found to have violated the Act on two occasions in a five-year period may be disbarred from public works projects for four years. Contractors are required to post prevailing wage rates at job sites.

Journeyperson Benefit Rate Update

IDOL’s enforcement position has been, and continues to be, that apprentices on Prevailing Wage-covered projects must receive the full journeyperson benefit rate. However, we understand there has been some uncertainty about the effective date of the statutory provision contained in House Bill 2488/Public Act 104-17, which is now delayed until July 1, 2026, per HB 1437/PA 104-434. This effective date change does not change IDOL’s enforcement position. However, any complaints received by IDOL are considered on a case-by-case basis, and during this period of time before HB 2488 takes effect, the Department’s focus will be on providing contractors with compliance assistance.

The Prevailing Wage rates are covered under two separate laws: Prevailing Wage Act and Illinois Procurement Code. The following are the prevailing wage classifications and rates the Department of Labor ascertained for each county within the State of Illinois.
