Ohio Prevailing Wage Rates: Thresholds, Payroll, and Penalties

Ohio prevailing wage rates are the trade-specific, county-by-county minimum pay scales that contractors must follow on qualifying public construction projects in Ohio. The Ohio Department of Commerce publishes a separate rate for every construction trade in each of the state’s 88 counties, and each rate splits into a base hourly wage and a required fringe benefit amount. If your project meets the cost threshold and isn’t in an exempt category, paying below that combined rate exposes you to back wages, penalties, stop-work orders, and debarment from future public work.¹

When Prevailing Wage Rates Apply

Coverage turns on two things: the type of construction and the estimated cost. Ohio treats vertical work (buildings) and horizontal work (roads, bridges, sewers, ditches) as separate categories, each with its own dollar thresholds and its own rules for new work versus repair.

Building Construction

New building construction is covered when the total project cost is fairly estimated to exceed $250,000. Renovation, repair, remodeling, or painting of an existing building is covered at $75,000. These figures are fixed by statute and do not adjust for inflation.²

Horizontal Construction

Roads, bridges, sewers, and ditches follow lower thresholds that adjust every two years. As of January 1, 2024, new horizontal construction is covered when the cost exceeds $98,974, and reconstruction or repair triggers at $29,653. The Director of Commerce recalculates these amounts based on the Building Cost for Skilled Labor Index published by Engineering News-Record, capped at a 3% change per year, with the next adjustment scheduled for January 1, 2026. Check the Department’s portal for the current figure before you rely on it.

Categorization controls, not labeling. A sewer-line project that a public authority informally treats as a “building” job may sit below $250,000 while still clearing the horizontal repair threshold by a wide margin. The nature of the work sets which number applies.

Projects That Are Exempt

Some public work sits outside the law entirely, regardless of cost. Assuming coverage where none exists inflates bids; assuming exemption where the law actually applies is worse.

School districts and educational service centers: every public improvement undertaken by or contracted through a school board or educational service center is exempt, and no public authority can voluntarily apply prevailing wage to a school project.²
Federally funded projects with federal wage rules: when a federal loan or grant prescribes minimum wages (typically Davis-Bacon), Ohio’s law steps aside and the federal rates govern. Davis-Bacon itself applies to federal contracts above $2,000.²³
Port authority projects.
Certain county and municipal hospital projects, if no funding comes from bonds backed by state, county, township, or municipal credit and no appropriated tax revenue is used. A qualifying hospital can still opt in voluntarily.²
Any portion of a project completed entirely with donated labor and materials.

What You Have to Pay

Rates come from the Department of Commerce, Division of Industrial Compliance, and are drawn from the collective bargaining agreements in force in each locality. An electrician’s rate in Cuyahoga County will not match an electrician’s rate in Athens County. The Department maintains a searchable portal by county and trade, and rates change whenever a new collective bargaining agreement is ratified, so a figure that was accurate at bid time may have moved by the time work starts. Verifying immediately before mobilization is standard practice.⁴

Base Wage Plus Fringe

Each schedule shows two numbers: the base hourly wage and a fringe amount covering health insurance, pension or retirement contributions, and apprenticeship training. If you provide those benefits through a qualifying plan, your contributions count toward the fringe obligation. If you don’t, the full fringe amount must be paid to the worker as additional hourly cash wages. There is no version of the calculation that skips the fringe.⁵

An example makes the point. If the schedule shows $35.00 base and $18.50 fringe, a contractor without a qualifying plan owes $53.50 per hour in direct wages, not $35.00.

Apprentices

You can pay apprentices at a reduced rate only when a collective bargaining agreement or understanding in that locality authorizes apprentice employment in that trade. If none exists, the worker must be classified by the work actually performed and paid the full journeyman rate for that classification.⁶

The apprentice-to-journeyman ratio on the job site cannot exceed the ratio set in the applicable schedule. Excess apprentices are treated as misclassified and are owed back wages at the full journeyman rate. A working foreman or supervisor can count toward the journeyman side of the ratio if properly classified in their own right.⁶

Certified Payroll

Every contractor and subcontractor on a covered project files certified payroll reports, and those reports are the enforcement backbone of the whole system. Each report lists the worker’s name and address, the last four digits of the Social Security number, the specific job classification, hours worked each day split into straight time and overtime, the base hourly rate, and fringe contributions. Hours over 40 in a week are paid at overtime.⁷

The state provides a form; a contractor’s own format is acceptable if it captures the same data. Each report carries a signed certification that hours were paid at the correct prevailing rate and that no improper deductions were made.⁷

Classification is where audits usually find money. Listing a skilled carpenter as a general laborer drops the required rate and creates immediate liability. Auditors look at what the worker actually did on site, not the label written on the form.

The first certified payroll goes to the project’s Prevailing Wage Coordinator within two weeks of the first pay period, and reports then follow the contractor’s regular pay cycle. The Coordinator is designated by the public authority that awarded the contract. All project payroll records must be kept in Ohio and available for inspection for at least one year after project completion, with inspection rights held by the Department of Commerce, the public authority, and the Coordinator.⁸

Penalties for Underpayment

Ohio stacks its penalties, and the arithmetic runs against the contractor from more than one direction at once.

Back Wages and Doubled Exposure

An underpaid worker recovers the full difference between what was paid and the correct prevailing rate, plus an additional 25% of that difference. Separately, the employer owes a 75% penalty to the Director of Commerce. Every dollar of underpayment therefore costs roughly two dollars: the dollar itself, 25 cents more to the worker, and 75 cents to the state.⁵

There is a narrow relief valve. If the Department finds that the underpayment came from a genuine misinterpretation of the law or a payroll error, it can order restitution without the added penalties. Underpayments under $1,000 also qualify for this simpler resolution once the worker is made whole.⁹

Stop-Work Orders

If the Department finds ongoing violations on an active project, it can halt the work. The order stays in force until the contractor posts a bond, set by the Department, guaranteeing payment of the correct prevailing wages. The contractor and any sureties get notice and a hearing before the order takes effect, but once it issues, work does not resume until the bond is in place.¹⁰

Debarment

A contractor convicted of or found to have intentionally violated the prevailing wage law is barred from all public improvement contracts for one year. A second intentional violation within five years extends the bar to three years. Debarment reaches the contractor, any subcontractor involved, and individual officers of those companies. Once the name is filed with the Secretary of State, no public authority in Ohio can award them work until the period runs.¹¹

Criminal Charges

A first offense is a second-degree misdemeanor. Subsequent offenses are first-degree misdemeanors.⁵

How Workers File a Complaint

A worker who believes they were paid less than the prevailing rate files a written complaint with the Department of Commerce, Division of Industrial Compliance, on the Department’s official form, signed and notarized. Pay stubs, time records, and any supporting documentation should be attached.¹²

The complaint must be filed within two years of project completion. Independent contractors and self-employed workers cannot file, and a complaint cannot cover a claim already reduced to a court judgment or one where the contractor has filed for bankruptcy. Once the Director accepts a properly documented complaint, the state takes assignment of the claim and pursues collection on the worker’s behalf, including attorney’s fees if the employer is found in violation.⁵
