Prevailing wage

Ohio prevailing wage and certified payroll rules

Ohio's prevailing wage law (Revised Code Chapter 4115) covers public improvements above set cost thresholds: $250,000 for new building work and $75,000 for remodeling, with lower road and sewer figures that the Director of Commerce adjusts every two years. School district projects are exempt, and certified payroll goes to the public authority's prevailing wage coordinator.

Yes. Ohio has a state prevailing wage law in Revised Code Chapter 4115, enforced by the Ohio Department of Commerce. It applies to public improvements built by or for a public authority when the total project cost is fairly estimated to exceed a threshold: $250,000 for new construction and $75,000 for reconstruction, remodeling, repair, or painting. Road, street, alley, sewer, ditch, and bridge-related work has separate, lower thresholds that start from statutory base figures and are adjusted by the Director of Commerce every two years, so confirm the current road and sewer numbers with Commerce before you bid. School district projects are exempt, and certified payroll goes to a prevailing wage coordinator named by the public authority.

What Ohio covers, and what it leaves out

A public authority is any state or local officer, board, or commission that can contract for a public improvement, plus institutions supported in whole or part by public funds when they spend those funds. A public improvement includes buildings, roads, streets, alleys, sewers, ditches, sewage plants, water works, and other structures built by or for a public authority. Work to fit out a newly built structure that a public authority leases within six months of completion also counts.

Ohio has more carve-outs than most states. Under ORC 4115.04, the law does not apply to:

  • School construction: projects by boards of education of school districts or governing boards of educational service centers. The statute says a public authority may not apply prevailing wage requirements to these projects.
  • Federally set wages: projects paid in whole or part with federal loans or grants where federal agencies set predetermined minimum wages.
  • Port authority projects and certain projects listed in ORC 176.05.
  • County or municipal hospitals that use no bond proceeds or tax-appropriated funds, though they can opt in.
  • Donated labor: the portions of a project done only with volunteer labor.

Thresholds also split by type of work. Say a city lets a $90,000 roof replacement on a library and a $90,000 new storage building on the same lot. The roof is remodeling, so it is measured against the remodeling threshold. The new building is measured against the much higher new construction threshold. With a $75,000 remodeling threshold and a $250,000 new construction threshold, the roof job is covered and the new building is not. Horizontal work is different: the road and sewer figures in the statute are base amounts that Commerce adjusts every two years, so get the current numbers from the Department of Commerce before you price a street or sewer job.

How rates are set and when you get them

The Director of Commerce determines the prevailing rates for laborers and mechanics by type of work and locality. On Department of Transportation work, ODOT sets a minimum rate for common laborers in each county. The public authority must get the wage schedule before it advertises for bids or starts the work with its own forces, put it in the specifications and on the bid forms, and send a copy of the bidding blank to the Director before award. If you are pricing a job and the schedule is missing from the bid documents, ask before bid day. Our guide on pricing prevailing wage jobs covers how to load the rate and the fringe benefits into your labor number.

Certified payroll and the prevailing wage coordinator

Ohio routes payroll through a person, not a portal. Under ORC 4115.071, the public authority must appoint a prevailing wage coordinator at least 10 days before the first wages are paid. The coordinator keeps the payroll reports and affidavits open for public inspection and reports late filings to the Director of Commerce.

  1. At the start of work: give the coordinator your schedule of pay dates.
  2. First certified payroll: within two weeks after the initial pay date.
  3. Ongoing reports: monthly, or weekly if the contract runs four months or less.
  4. Contents: each worker's name, address, last four digits of the Social Security number, daily and weekly hours, hourly rate, classification, fringe payments, and deductions, certified as correct and complete.
  5. Before final payment: file the affidavit the coordinator must receive before the public authority releases final payment.

Penalties

Under ORC 4115.10, a worker paid less than the required rate can recover the difference plus 25 percent of that difference. The employer also pays the Director 75 percent of the underpayment as a penalty. Workers have 90 days after the Director's determination of a violation to sue, and the Director can bring the collection action if no worker does. A contractor or sub is not liable for those penalties caused by a lower-tier sub's violation if it made a good faith effort to ensure compliance, which is one more reason to collect and check sub payroll every month.

How Ohio differs from Davis-Bacon

The federal Davis-Bacon Act covers federally funded or assisted construction over $2,000, uses SAM.gov wage determinations, and requires weekly payroll, usually on the optional WH-347. Ohio's thresholds are much higher, payroll is monthly for most contracts and goes to a local coordinator, schools are exempt, and the state law steps aside on federally funded projects where federal agencies set the wages. That last point means a job with federal funding and a federal wage determination usually follows Davis-Bacon rather than both sets of rules. Confirm with the contracting authority.

Before bidding Ohio public work, check the Ohio contractor license rules, Ohio mechanics lien and bond options, and Ohio prompt payment terms. Smart Business Automator prepares certified payroll from crew time coded by job and classification, so the monthly report for the coordinator is ready when the pay application goes out.

Frequently asked questions

What is the prevailing wage threshold in Ohio?

$250,000 for new construction and $75,000 for reconstruction, remodeling, repair, or painting. Road, street, sewer, ditch, and bridge-related work has lower thresholds that the Director of Commerce adjusts every two years from statutory base figures of $78,258 and $23,447, so check the current road amounts with the Department of Commerce.

Does Ohio prevailing wage apply to school construction?

No. ORC 4115.04 exempts projects by school district boards of education and educational service center governing boards, and says a public authority may not apply prevailing wage requirements to them.

How often is certified payroll due in Ohio?

The first certified payroll is due within two weeks after the initial pay date. After that, reports are monthly, or weekly if the contract runs four months or less. They go to the public authority's prevailing wage coordinator.

What are the penalties for underpaying prevailing wage in Ohio?

The worker can recover the difference plus 25 percent, and the employer pays the Director of Commerce a penalty equal to 75 percent of the underpayment, plus costs and attorney's fees if the case is won.

Does Ohio prevailing wage apply on federally funded jobs?

Ohio's law does not apply where federal funds pay for all or part of the project and federal agencies set predetermined minimum wages. In that case the federal Davis-Bacon rules govern.
