Understanding Illinois Prevailing Wage Requirements

Prevailing wage laws ensure that workers on government construction projects receive fair wages based on local standards. In Illinois, these requirements apply to specific public works projects based on funding sources and project costs.

Key Prevailing Wage Triggers

  • State Projects: Triggered by state-specific thresholds and statutes
  • Federal Davis-Bacon: Applies when federal funds are used (threshold: $2,000)
  • Local Requirements: Some counties and cities have additional rules
  • Project Type: New construction vs. renovation may have different thresholds

This tool helps contractors, project managers, and procurement officers quickly determine if prevailing wages apply to their specific project in Illinois.
