Building a Public School, Road or Facility? Your Required Pay May Be Higher Than Your Check Shows
The ordinary minimum wage is not always the correct benchmark on publicly funded construction. Illinois requires covered contractors and subcontractors to pay laborers, workers and mechanics the local prevailing rate, consisting of hourly cash wages plus fringe benefits. IDOL published schedules for work performed on or after August 15, 2026.

Key takeaways
- The Act covers qualifying public works, not every private construction project.
- Rates vary by county, trade and effective date.
- Required compensation includes cash wages and fringe benefits.
- A payroll title may not reflect the proper classification.
- IDOL accepts prevailing-wage complaints, including a Spanish form.
Who may be covered?
The Act applies to laborers, workers and mechanics employed by contractors and subcontractors on covered public works. Roads, public schools, government facilities and infrastructure may qualify, but the funding, contract and actual work must be examined.
Why Chicagoland geography matters
Rates are locality-specific. Workers moving among Cook, Kane and DuPage Counties should not assume one rate follows them everywhere. Elgin lies in Cook and Kane; Hanover Park spans Cook and DuPage. The physical project location—not merely the employer’s office—helps determine the schedule to review.
Pay-record checklist
| Data point | Question |
|---|---|
| Project | Is it covered public work? |
| Location | Where was the work physically performed? |
| Date | Which schedule was effective? |
| Trade | What duties did the worker actually perform? |
| Cash wage | Does it match the classification? |
| Fringe benefits | Were qualifying benefits provided or paid? |
| Hours | Are all hours and applicable overtime recorded? |
Warning signs
Lower classification than actual duties
A worker may be called a helper while regularly performing duties associated with another classification. Actual work matters.
Missing fringe-benefit component
The prevailing rate includes cash wages and fringe benefits. The contractor should be able to explain compliance with both.
Off-the-clock or split payments
Cash payments, multiple checks or instructions not to record time can complicate proof but do not erase statutory rights.
Preserving evidence
Keep pay stubs, deposits, tax forms, dates, hours, project locations, daily tasks, supervisor messages and lawful photographs of project and rate notices. Do not access restricted records without authorization.
