Prevailing wage

Michigan prevailing wage and certified payroll rules

Michigan's old prevailing wage law was repealed in 2018, but 2023 PA 10 brought it back for state projects bid on or after February 13, 2024. Contractors now need a state project registration, and certified payroll goes into LEO's online database within 10 days after each pay period.

Yes, Michigan has a prevailing wage law again. The U.S. Department of Labor's state table still lists Michigan's prior law as repealed in 2018, but the Legislature enacted 2023 PA 10, effective February 13, 2024, and amended it with 2024 PA 110, effective April 2, 2025. It covers state projects: construction, alteration, repair, painting, demolition, and improvement of public buildings, schools, works, bridges, highways, or roads that are authorized by a public contracting agent and sponsored or financed in whole or in part by the State. The act sets no minimum contract amount. Since 2025 it also reaches large private solar, wind, and energy storage projects.

Which Michigan projects are covered

The trigger is state money plus a public contracting agent: a state officer, board, commission, school board, or state institution supported by state funds. A school district using state dollars for an addition is covered. The act has carve-outs. Contracts that already require federal Davis-Bacon rates under 40 USC 3141 to 3148 are exempt, as are contracts whose wage schedules match local collectively bargained rates. Projects paid from a school millage authorized before the act took effect are excluded, and so are contracts bid before February 13, 2024.

2024 PA 110 added energy facility projects: new construction, major alteration, or repowering of solar, wind, or energy storage facilities with a nameplate capacity of 2 megawatts or more. For these jobs the contracting agent can be a private company. If you build utility-scale solar in Michigan, prevailing wage, registration, and payroll filing are now part of the bid.

How LEO sets Michigan rates

Michigan rates do not come from a contractor wage survey. LEO, as commissioner, sets wages and fringe benefits at the rates that prevail on similar projects in the locality under collective bargaining agreements. Where no agreement exists, LEO uses the rates from the nearest and most similar neighboring locality that has one. Locality means the county, city, village, township, or school district where the work is done.

  • Before bidding: the contracting agent must have LEO determine the rates for every class of construction mechanic in the contract. The schedule goes into the specifications and onto the bid form.
  • 90 day rule: if the contract is not awarded or work does not start within 90 days of the determination, LEO must redetermine the rates before award.
  • Posting and records: post all rates on site in a conspicuous place and keep a record of each mechanic's name, occupation, and actual wages and benefits paid.
  • Public rates: all determined rates are filed with LEO and made available to the public through its Wage and Hour Division.

State project registration

This is the part many Michigan subs miss. Under section 2a, neither a contractor nor a subcontractor may bid or perform work on a state project without a state project registration. A prime cannot list an unregistered sub on a bid or sign a subcontract with one, and must include copies of its own and its selected subs' registrations with the bid. The application covers ownership, tax and unemployment insurance numbers, and proof of required licenses. LEO decides within 15 business days of a complete application, and the registration lasts 1 year. Check your trade licensing on the Michigan contractor license page before applying.

Certified payroll: the April 2, 2026 switch to online filing

Section 22 requires contractors and subs to transmit certified payroll within 10 days after the end of each pay period. For the first year after 2024 PA 110 took effect, payroll went to the contracting agent. Starting one year later, on April 2, 2026, payroll goes into LEO's online certified payroll database. Each record shows, for every construction mechanic, the classification, skill level (apprentice, journeyman, or other), gross wages, hours worked each day, start and end times, hourly rate, overtime rate, and fringe rate. You attest by electronic signature that the record is complete and the rates meet the act.

Two exceptions apply: contractors already required to send certified payroll to the state transportation department on a state project, and energy facility work that is only routine maintenance or repair. Submitting a payroll you know contains a false statement is a separate violation.

Penalties and how Michigan differs from Davis-Bacon

A person who violates the act faces a civil fine of up to $5,000, and LEO may assess up to $5,000 per violation plus an additional 10 percent penalty, due within 15 working days. Contractors and subs are jointly and severally liable. The contracting agent can terminate the contractor's right to proceed on the underpaid part of the work and hold the contractor and its sureties for the extra cost. Workers can sue for back pay, and retaliation complaints must be filed with LEO within 90 days. LEO will not accept complaints more than 3 years after the violation.
