Ohio general contractor license requirements

Ohio does not issue a general-contractor license. The state board — the Ohio Construction Industry Licensing Board, part of the Department of Commerce’s Division of Industrial Compliance — licenses commercial contractors in five specialty trades and nothing else. The board’s own lookup guidance says it plainly: residential contractors are not required to be licensed by the state.

That puts Ohio in the same family as Texas: trades licensed by the state, general building handed to local government. The general versus specialty license comparison explains why so many states split it this way, and the state-by-state requirements guide shows where Ohio sits against the rest.

OCILB issues one kind of credential — the contractor license, which the board also calls the Master license — in five trades. The 17-member board works in four sections, three of them by trade:

The license is commercial. Ohio’s contractor licensing law, Revised Code chapter 4740, makes building and health departments that run a contractor registration demand the state license before issuing a commercial permit — and lets them demand it for residential work too. Electricians should read the electrical license guide; if you are choosing between pipes and ducts, the plumbing vs HVAC comparison lays out the two ladders.

The bar is the same across all five trades. It is an experience test first and an exam second — the board will not schedule you for the exam until it has approved the application.

2. § 2Be a US citizen, or a legal alien with proof of that status.OCILB
3. § 3Five years as a tradesperson in the trade you are applying for, immediately before the application date — or be an Ohio-registered engineer with three years of business experience in that trade.OCILB
4. § 4No disqualifying offence under the list the board publishes (H.B. 263, 133rd General Assembly).H.B. 263
5. § 5After board approval, a state (BCI) and federal (FBI) background check — valid for one year.OCILB
6. § 6Pass the PSI licensing examination in the trade.PSI
7. § 7Carry contractor liability coverage of at least $500,000.OCILB
8. § 8Pay the application and licensing fees.OCILB

Five years is where most applications are won or lost, so the board spells out what counts as proof. Tax records alone are not enough:

The board’s trade sections meet every other month, and an application has to reach the board two weeks before a meeting to be reviewed at it; a late one waits for the next. The background check then has a one-year life: if the exam slips past a year from approval, both checks are repeated. The license exam guide covers how to prepare once you are approved.

The board’s own fees are small and charged per trade, so a contractor holding plumbing and hydronics pays each one twice. The exam is a separate charge, set and collected by PSI.

Our license cost calculator puts the board fees beside the other costs of getting licensed, so the small numbers above are not mistaken for the budget.

Licenses renew on a one-year or a three-year cycle, and the continuing-education hours scale with it: 8 hours for a one-year renewal, 24 hours for a three-year one. In the electrical trade, half of those hours must be code courses.

Proof of insurance no longer goes in with the renewal form, but the $500,000 cover still has to exist, in the name of a single contracting company. A licensee who stops contracting can put the license in escrow instead of letting it lapse: no CE, no insurance, just the yearly renewal fee — and up to 24 hours of CE plus proof of insurance to come back. The renewal guide and the renewal tracker handle the dates.

An OCILB license belongs to a person but is assigned to a company, and most disciplinary trouble comes from that gap. The board’s stated rules:

• The license is non-transferable and is assigned to one company name — no DBAs.
• You may not pull permits for an unlicensed competitor. Pull one, and you are the contractor in charge, available to OCILB's investigators.
• Everyone working under the license is on your payroll with a W-2, or hired through a nationally recognised temporary agency. A worker paid on a 1099 needs their own state license.
• The license number goes on every advertisement that carries the company name — vans, cards, letterhead, web ads.
• Leave the company and the license stays with it for 90 days from OCILB's written notice, unless the old company signs a letter of release.
• Let it lapse for more than a year and you reapply and retest.

Ohio has reciprocal agreements with 11 states, trade by trade. The condition is the same everywhere: your out-of-state license must have been earned by passing that state’s exam. Where marked, Ohio also wants its Business and Law exam.

A reciprocity file is a notarised reciprocity application, a verification form signed by the other state’s board and the $25 fee per trade. Texas is the odd one out on the list: it has no state general-contractor license either, and Ohio accepts only a Texas master electrician license earned by passing the Texas exams — see the Texas sheet. For the wider picture, the reciprocity guide explains what these agreements do and do not waive, and the reciprocity checker runs the question for any pair of states.

For a general contractor, a remodeller or a roofer, Ohio’s gate is the local building department. Whether you register, what it costs and what it asks for are set by the city, county or township that holds code-enforcement authority over the address — and two neighbouring jurisdictions can answer differently. We do not print local fees for that reason.
