Ohio's law is active, and it turns on a dollar threshold most contractors get wrong. Here are the thresholds, where the official rate schedules live, and the certified payroll deadline that runs off your first pay date.

Ohio is a straightforward state in a region that is not. Its prevailing wage law is Ohio Revised Code Chapter 4115, Wages and Hours on Public Works, and the operative sections run from 4115.03 through 4115.16. The Director of Commerce determines the rates, and the Department of Commerce's Division of Industrial Compliance, Wage and Hour publishes them and enforces the chapter. It is in force in 2026, it has not been repealed, and the questions that actually decide your job are the threshold, the coordinator and the payroll deadline.
Chapter 4115 is the whole framework
ORC 4115.03 carries the definitions and thresholds, 4115.04 the rate determination and exemptions, 4115.05 the locality rate that controls the contract, 4115.06 the required contract provision, 4115.07 payment and records, 4115.071 the prevailing wage coordinator, and 4115.10 through 4115.133 the prohibitions, investigations and debarment.
The trigger is a public improvement
ORC 4115.03 defines public improvement as all buildings, roads, streets, alleys, sewers, ditches, sewage disposal plants, water works, and all other structures constructed by public authorities or by contractors working for them, with a carve-out for certain soil conservation district projects that are at least 75 per cent privately funded.
Rates are determined before bids go out
ORC 4115.04 requires every public authority authorized to contract for or undertake construction of a public improvement to have the Director of Commerce determine the prevailing rates of wages before advertising for bids or undertaking the construction with its own forces.
The locality rate controls the contract
ORC 4115.05 sets the standard as the prevailing rate of wages then payable in the same trade or occupation in the locality, based on collective bargaining agreements in effect when the contract is made. Labor organizations file the relevant portions of their agreements with the Director within 90 days of execution.
Fringe benefits are part of the obligation
Ohio treats the wage and the fringe as two components of one rate. ORC 4115.05 requires the contractor to furnish each employee individual written notification separating compensation into the hourly rate of pay and the fringe payments, which is only meaningful because both are owed.
Not a filing to a central portal
This is the biggest operational difference from Illinois or Michigan. Ohio's certified payroll goes to a person, the prevailing wage coordinator at the contracting public authority, on the schedule in ORC 4115.071. It is not a statewide upload.

Ohio is a threshold state. Below the figure for your project type, Chapter 4115 does not attach at all. Above it, everything on this page applies.
| Project type | New construction | Reconstruction, alteration, repair, remodeling, renovation, painting |
|---|---|---|
| Public improvement other than road and bridge work | Over $250,000 | Over $75,000 |
| Roads, streets, alleys, sewers, ditches and similar work | Over $78,258 as printed in ORC 4115.03, then adjusted biennially | Over $23,447 as printed in ORC 4115.03, then adjusted biennially |
Why we will not print a current road and bridge number
The two road and bridge figures above are the ones written into ORC 4115.03, and the statute does not leave them there. ORC 4115.034 requires the Director of Commerce to adjust the threshold levels on the first day of January of every even-numbered year, using the average increase or decrease for the two preceding years as set forth in the Engineering News-Record construction cost index, with no single year's change exceeding three per cent. Thirty years of that ratchet means the numbers in force today are meaningfully higher than the statutory text. Rather than publish a figure we cannot confirm on an Ohio state page, we are telling you exactly where it comes from: get the current road and bridge thresholds from the Department of Commerce, Division of Industrial Compliance, Wage and Hour before you rely on one. The $250,000 and $75,000 figures for other public improvements are stated directly in ORC 4115.03 and are repeated for Ohio on the U.S. Department of Labor's state threshold table.
Sources: ORC 4115.03, ORC 4115.033, ORC 4115.034, dol.gov Dollar Threshold Amount for Contract Coverage.
ORC 4115.04(B) is a short list with two entries that reshape a lot of Ohio bidding.
Exempt: federally funded work with federal predetermined wages
Where the federal government or any of its agencies furnishes all or any part of the funds by loan or grant and prescribes predetermined minimum wages for mechanics and laborers, Chapter 4115 does not apply. This is the no-double-jeopardy clause: on a federally funded Ohio job you follow Davis-Bacon, not the state law on top of it.
Exempt: school districts and educational service centers
Public improvements undertaken by, or under contract for, the board of education of any school district or the governing board of any educational service center are exempt. This surprises contractors coming from states where school construction is the heart of prevailing wage work.
Exempt: certain county and municipal hospital improvements
The section exempts county and municipal hospital improvements that meet specified funding conditions, while letting the hospital choose to apply the requirements voluntarily.
Exempt: port authorities and some ORC 176.05 projects
Public improvements undertaken by port authorities as defined in the statute are exempt, as are projects described in divisions (D)(1)(a) to (D)(1)(e) of ORC 176.05.
Exempt: donated labor
Any portion of a public improvement undertaken and completed solely with labor donated by the individuals performing it, by a labor organization and its members, or by a contractor or subcontractor donating all labor and materials, is exempt.
Covered: everything else above threshold
If the work is a public improvement under ORC 4115.03, the cost clears the threshold for its type, and no exemption in 4115.04(B) fits, then the prevailing rate, the records, the coordinator reporting and the posting all apply to the prime and to every subcontractor.
Read the list yourself at ORC 4115.04. An exemption from Chapter 4115 is not an exemption from Davis-Bacon, and on a school or hospital job carrying federal grant money the federal rules can still be the binding ones.
There is one official source, and it is the state's own system. The Ohio Department of Commerce runs a Prevailing Wage Portal publishing the active commercial prevailing wage rates for all construction trades in all jurisdictions within Ohio, for projects governed by ORC Chapter 4115. Access runs through registration and login, and the Division of Industrial Compliance, Wage and Hour is the office behind it.
We deliberately do not print Ohio wage rates on this page. Rates change by trade and jurisdiction, and a stale number on a marketing site is how a contractor underpays a crew. Use the state portal and the schedule attached to your contract. For federal work in Ohio, use the wage determination in the contract and our free Davis-Bacon wage lookup.
This is the section to read twice. Ohio's reporting clock does not run off the week ending date the way the federal rule does, and it does not run monthly from day one the way Illinois does. ORC 4115.071 sets it up around your first pay date and around a named person at the awarding agency.
The public authority must appoint a coordinator
Each contracting public authority that enters into a contract whose contractor and subcontractors are subject to ORC 4115.03 to 4115.16 must designate and appoint one of its own employees to serve as the prevailing wage coordinator. If nobody has told you who that is on your job, ask.
Certified payroll within two weeks after the initial pay date
The contractor or subcontractor delivers to the prevailing wage coordinator a certified copy of its payroll within two weeks after the initial pay date. That first delivery is the one people miss, because it is keyed to the first pay date rather than to a calendar day of the month.
Then supplemental reports each month
After that first certified copy, supplemental reports are required for each month thereafter, going to the same coordinator.
Short contracts report weekly instead
If the life of the contract is expected to be no more than four months, the supplemental reports are filed each week rather than monthly. Check the expected contract duration before you assume a monthly rhythm.
What each report must show
For each employee: name, current address, the last four digits of the Social Security number, hours worked during each day of the pay periods covered and the total for each week, hourly rate of pay, job classification, fringe payments, and deductions from wages.
The coordinator's side of it
The coordinator maintains the payroll files for public inspection, determines payment dates, receives and monitors payroll submissions, establishes procedures for compliance, collects the final affidavits, and reports filing delinquencies to agency leadership and to the Director of Commerce. Delinquency is visible upward, which is why late reports become contract problems quickly.
Records open to inspection, kept a year after completion
ORC 4115.07 requires full and accurate payroll records of wages paid and hours worked for each employee, open to inspection by any authorized representative of the contracting public authority, including the coordinator, or by the Director of Commerce at any reasonable time. The records may not be destroyed or removed from the state for one year following completion of the public improvement.
A final affidavit before final payment
On completion of the public improvement and prior to final payment, each contractor and subcontractor files an affidavit with the contracting public authority stating full compliance with ORC 4115.03 to 4115.16. ORC 4115.071 makes providing that affidavit part of the contractor's reporting duty.
Sources: ORC 4115.071, ORC 4115.07. Ohio has no statewide upload portal for certified payroll in Chapter 4115; the report goes to the coordinator at the contracting public authority.
The rates below are illustrative placeholders, not Ohio rates and not actual state rates of any kind. Use the published rate for your trade and jurisdiction, and follow the overtime treatment your schedule and contract specify.
One laborer on an Ohio public improvement above the threshold. Say the schedule for the classification shows a $34.00 base rate and an $18.00 hourly fringe rate. The crew works eight hours Monday through Friday plus four hours Saturday, so 44 hours in the week, and the contract applies time and a half to the base rate for hours over 40.
| Line | Math | Amount |
|---|---|---|
| Straight time | 40 hrs at $34.00 base | $1,360.00 |
| Overtime hours | 4 hrs at 1.5 x $34.00 base = $51.00 | $204.00 |
| Total cash wages before fringe | $1,360.00 + $204.00 | $1,564.00 |
| Fringe obligation | 44 hrs at the $18.00 fringe rate | $792.00 |
| Total wage and fringe obligation | $1,564.00 + $792.00 | $2,356.00 |
| Credit for bona fide plans | 44 hrs at $13.00 contributed | $572.00 |
| Cash in lieu still owed | 44 hrs at the remaining $5.00 | $220.00 |
| Cash the worker actually receives | $1,564.00 + $220.00 | $1,784.00 |
Two things trip people up. The overtime multiplier in this example runs on the base rate, so the fringe rate is not multiplied for the four overtime hours. And the fringe obligation is owed on all 44 hours, not just the straight-time 40. Underfund the plan and the shortfall becomes cash wages, which is the $220.00 line. The written notification you owe each employee under ORC 4115.05 has to show that split, so the $13.00 plan credit and the $5.00 cash cannot be blurred together on your books.

They do not stack. Davis-Bacon applies to federally funded and federally assisted construction in Ohio on its own authority, and ORC 4115.04(B)(1) then steps back where the federal government prescribes predetermined minimum wages.
| Requirement | Ohio ORC 4115 | Federal Davis-Bacon |
|---|---|---|
| Governing law | ORC 4115.03 to 4115.16 | Davis-Bacon Act and the Related Acts |
| Applies to | Public improvements by public authorities | Federal and federally assisted construction |
| Contract threshold | Over $250,000 new, over $75,000 repair type; lower for road and bridge | In excess of $2,000 |
| Agency | Director of Commerce, Division of Industrial Compliance, Wage and Hour | U.S. DOL Wage and Hour Division |
| Rate source | Rates determined by the Director before bids; state Prevailing Wage Portal | Wage determination in the contract |
| Who receives the payroll | The prevailing wage coordinator at the public authority | The contracting or sponsoring federal agency |
| First report due | Certified copy of payroll within two weeks after the initial pay date | First weekly payroll for the first covered week |
| Ongoing frequency | Monthly supplemental reports, or weekly if the contract is four months or less | Weekly |
| Deadline rule | ORC 4115.071 | Within 7 days after the regular payment date (29 CFR 3.4(a)) |
| Form | No state form specified in the chapter | Optional Form WH-347 |
| Certification | Final affidavit of compliance before final payment (ORC 4115.07) | Statement of Compliance (29 CFR 5.5(a)(3)(ii)(C)) |
| Record retention | Not destroyed or removed from the state for 1 year after completion | 3 years after completion of the contract |
| Address on the report | Employee's current address is required | Address stays off the submitted weekly payroll |
| Debarment | 1 year for a first intentional violation, 3 years for a subsequent one | 3 years under the Davis-Bacon Act |
On the federal side the certified payroll goes to the contracting or sponsoring agency within 7 days after the regular payment date of the payroll period, and each one carries a Statement of Compliance indicating that the payrolls are correct and complete and that each laborer or mechanic has been paid not less than the applicable Davis-Bacon prevailing wage rate for the work performed. Full Social Security numbers must never appear on a submitted weekly payroll; use an individually identifying number such as the last four digits, and keep home addresses, phone numbers and email addresses off the submitted copy. That is a real difference from Ohio, where ORC 4115.071 asks for the employee's current address on the report to the coordinator, so do not reuse one document for both obligations without checking what each one wants.

Ohio splits the money two ways: a premium to the underpaid worker and a separate penalty to the state. Both are computed off the same shortfall, which is why a small classification error can multiply quickly across a crew.

We produce the reports. You deliver them to the prevailing wage coordinator or the federal agency. We never submit anything to any agency on your behalf.
To be straight with you: we build state-specific report formats for California, Illinois and New York today. Chapter 4115 does not prescribe a state form, so Ohio work runs on our certified payroll reports carrying the ORC 4115.071 fields and on the federal WH-347. If Ohio publishes a required state format, that is the point we would build it.

Start Free TrialYes. Ohio's prevailing wage law is Ohio Revised Code Chapter 4115, Wages and Hours on Public Works, running from ORC 4115.03 through 4115.16. It is administered by the Director of Commerce, and the Ohio Department of Commerce's Division of Industrial Compliance, Wage and Hour publishes the commercial prevailing wage rates for every construction trade in every jurisdiction in the state. Unlike Indiana and unlike Michigan between 2018 and 2024, Ohio's law has stayed on the books.
ORC 4115.03 sets them by project type. For a public improvement other than road and bridge work, prevailing wage attaches when the cost is over $250,000 for new construction, or over $75,000 for reconstruction, enlargement, alteration, repair, remodeling, renovation, or painting. The U.S. Department of Labor's state threshold table lists Ohio at the same $250,000 for new construction and $75,000 for remodeling. Road, street, alley, sewer, ditch and similar work has its own lower thresholds, which are adjusted every two years.
ORC 4115.03 states the road and bridge figures as over $78,258 for new construction and over $23,447 for reconstruction, enlargement, alteration, repair, remodeling, renovation, or painting, and then requires those figures to be adjusted. Under ORC 4115.034 the Director of Commerce adjusts the threshold levels on the first day of January of every even-numbered year using the average change in the Engineering News-Record construction cost index for the two preceding years, with no single year's increase or decrease exceeding three per cent. Because of that ratchet, the current published road and bridge thresholds are higher than the figures printed in the statute. Get the current numbers from the Department of Commerce before you rely on them; we do not publish a threshold figure we cannot confirm on a state page.
No. ORC 4115.033 says no public authority shall subdivide a public improvement project into component parts or projects whose cost is fairly estimated to be less than the threshold levels in ORC 4115.03. Subdivision is allowed only where the separate projects are conceptually distinct and unrelated, or address independent needs.
The Ohio Department of Commerce runs a Prevailing Wage Portal at pwr.com.ohio.gov, which publishes the active commercial prevailing wage rates for all construction trades in all jurisdictions within the state, for projects governed by ORC Chapter 4115. Access is through registration and login. Separately, ORC 4115.04 requires the public authority, before advertising for bids or doing the work with its own forces, to have the Director of Commerce determine the prevailing rates of wages, so the schedule for your project should come to you with the contract.
ORC 4115.04(B) lists the exemptions, and two matter most in practice. Federally funded work is exempt where the federal government or one of its agencies furnishes all or any part of the funds by loan or grant and prescribes predetermined minimum wages for mechanics and laborers, which means Davis-Bacon takes over rather than the state law applying on top. Public improvements undertaken by or under contract for a school district board of education or an educational service center governing board are also exempt. The section additionally exempts certain county and municipal hospital improvements, projects described in ORC 176.05(D)(1)(a) to (e), port authority improvements, certain work activity program labor, and any portion of a public improvement completed solely with donated labor.
Yes, and it goes to a specific person. Under ORC 4115.071 each contracting public authority must designate and appoint one of its own employees as the prevailing wage coordinator. The contractor or subcontractor delivers to that coordinator a certified copy of its payroll within two weeks after the initial pay date, then supplemental reports for each month thereafter. If the life of the contract is expected to be no more than four months, the supplemental reports are filed each week instead of monthly.
ORC 4115.071 requires each report to show, for each employee, the employee's name, current address, the last four digits of the employee's Social Security number, the number of hours worked during each day of the pay periods covered and the total for each week, the employee's hourly rate of pay, the employee's job classification, fringe payments, and deductions from wages. Note that Ohio asks for the current address, which the federal WH-347 does not carry on a submitted copy.
Under ORC 4115.071 the coordinator maintains the payroll files for public inspection, determines payment dates, receives and monitors payroll submissions, establishes procedures for compliance, collects the final affidavits, and reports filing delinquencies to agency leadership and to the Director of Commerce. If you cannot work out where your certified payroll goes on an Ohio job, the coordinator is the person to ask, and the contracting public authority has to have one.
ORC 4115.07 requires contractors and subcontractors to keep full and accurate payroll records of wages paid to each employee and hours worked by each employee, open to inspection by any authorized representative of the contracting public authority, including the prevailing wage coordinator, or by the Director of Commerce at any reasonable time. Those records may not be destroyed or removed from the state for one year following completion of the public improvement. On completion and before final payment, each contractor and subcontractor files an affidavit with the contracting public authority stating full compliance with ORC 4115.03 to 4115.16.
Yes. ORC 4115.07 requires a legible statement of the schedule of wage rates to be posted in a prominent and accessible place on the site of the work, or on the internet in a manner accessible to the contractor's or subcontractor's employees. ORC 4115.05 separately requires the contractor to furnish each employee individual written notification that separates compensation into the hourly rate of pay and the fringe payments.
ORC 4115.10 lets the employee recover the difference between the fixed rate of wages and the amount actually paid, plus a sum equal to twenty-five per cent of that difference as damages, and requires the employer to pay the Director a penalty of seventy-five per cent of the difference. An employee has ninety days from the Director's determination of a violation to bring the action. ORC 4115.13 defines an intentional violation as a willful, knowing, or deliberate failure to comply and provides for restitution plus a bar on contracting for public improvements. Under ORC 4115.133 a first intentional violation carries a one-year bar and a subsequent one carries three years.
They do not stack. ORC 4115.04(B)(1) exempts a public improvement where the federal government or one of its agencies furnishes all or part of the funds by loan or grant and prescribes predetermined minimum wages, so on a federally funded Ohio job you follow Davis-Bacon: the wage determination in the contract, weekly certified payroll to the contracting or sponsoring agency within 7 days after the regular payment date (29 CFR 3.4(a)), and the Statement of Compliance under 29 CFR 5.5(a)(3)(ii)(C). Davis-Bacon covers contracts in excess of $2,000 for construction, alteration, or repair of public buildings or public works, and the Related Acts extend it to federally assisted work.
We produce the certified payroll records you submit. Enter hours by day and classification and we calculate straight time, overtime, the fringe credit and cash in lieu, then generate a certified report carrying the worker, classification, daily and weekly hours, hourly rate, fringe payments and deductions your Ohio coordinator asks for, plus the federal WH-347 for Davis-Bacon work in Ohio. Lydia flags wages below the rate you entered for the classification before you certify. You file with the prevailing wage coordinator or the federal agency; we do not submit anything to any agency on your behalf.
