Illinois prevailing wage
State law, federal determinations, and how to find the rate that applies
- Illinois has its own prevailing-wage law (820 ILCS 130), with no contract-size threshold (all covered public works), administered by Illinois Department of Labor.
- The U.S. Department of Labor has 70 active federal Davis-Bacon wage determinations covering 102 Illinois counties as of (latest revision date), each setting county rates by trade for federally funded construction.
- Market context: the average private construction worker in Illinois earned $1,803/week (≈ $45.08/hour) in Q1 2026, rank #7 of 51 states, per the BLS Quarterly Census of Employment and Wages - an industry average, not a prevailing-wage rate.
No dollar threshold; covers fixed works constructed or demolished by a public body or paid wholly or partly from public funds.
How to find the required rate
- State or locally funded project: use the rate schedules from Illinois Department of Labor - official Illinois prevailing-wage portal.
- Federally funded project: find the county in the Illinois determination index and open the official SAM.gov document for your construction type.
- Read the classification line - base rate plus fringe (how to read a determination); compute totals and overtime with the calculator.
