Ohio Contractor & Trade Licensing Costs (2026)

One board, five commercial trades, and nothing residential

OCILB, a section of the Ohio Department of Commerce, licenses contractors under Chapter 4740 of the Ohio Revised Code. The license does not float free: it is assigned, together with the holder's liability insurance, to a single contracting company, and it authorizes commercial work through that company only. Change the company and the board is involved again.

Of the five trades the board licenses, this site covers three with full fee schedules: electrical contracting, plumbing contracting and HVAC contracting. The other two, hydronics and refrigeration, run on the same board pattern but have their own examinations. Note the second one if you do cooling work: an HVAC license does not authorize refrigeration contracting in Ohio. The two are separate licenses.

The word commercial is the hinge. Commercial electrical, plumbing and HVAC work in Ohio requires the OCILB license, held for the trade and assigned to the company doing the work. Residential work in the same three trades requires no state license at all. It is regulated by the city or county where the work sits.

One price for all three trades: the $188 first-time total

Most state boards price each trade differently. OCILB does not. Whichever licensed trade you apply in, the state and exam charges are identical: a $25 examination application to the board, $138 to PSI for the two examinations, and a $25 initial license fee after you pass. That is $188 the first time, on the electrician, plumber and HVAC pages alike.

The two examinations are shared across trades. Every applicant takes a Business and Law exam, 50 questions in two hours, and then a trade exam of 100 questions in four hours, built on that trade's code. Both are open-book, with references allowed if they are highlighted and indexed but not written in, and both must be passed at 70 percent. PSI charges $69 for each section.

Two costs sit outside the $188, and honest budgeting names them. The BCI and FBI background checks are priced by the fingerprinting provider, not the board, and OCILB publishes no figure for them. The larger one is insurance: at least $500,000 of contractor liability insurance, proved before the license issues. The insurance premium is the real annual cost of holding this license.

The real gate is five years of work, proved on paper

OCILB requires five years of experience as a tradesperson in the trade, in the years immediately before you apply, and it wants that experience proved rather than asserted. The standard evidence is a permit for each of the last five years, covering work performed under a licensed contractor, filed together with five years of tax documents.

Careers that took another shape have their own doors. The board accepts an active journeyman's card, or a completion certificate from an apprenticeship program approved in Ohio or by the US Department of Labor, or 40 hours of code continuing education in the trade from an approved agency. Ohio-registered professional engineers qualify with three years of construction business experience in the trade, and so do five-year government inspectors.

The order of steps after approval is fixed. The board's approval to sit the examinations lasts one year only. Inside that year you must obtain the BCI and FBI background checks, because the board requires them after approval and before the exam, and then pass both examination sections. Let the year expire with either step undone and the route starts again.

No state bond, but cities write rules of their own

There is no surety bond for the OCILB license itself, in any trade. Bonding sites that quote an Ohio contractor bond for this license are describing something else, usually a city requirement. Columbus is the worked example on our trade pages: OCILB licensees doing commercial work in the city must also register with the city and post a $25,000 city bond. That bond is Columbus's, not the state's.

The municipal layer runs deeper than bonds. Ohio has no statewide journeyman or master license in any trade, because those grades are municipal credentials here. Columbus, Cleveland, Cincinnati and Toledo each run their own journeyman or master programs, with separate exams and fees, and none of them is interchangeable with the state license or with a neighboring city's card.

Renewal is cheap and annual, and the real number is eight hours

Renewal costs $60 a year, and the board also offers a three-year renewal at $180 for contractors who prefer one transaction. Either way the license stays live only while the $500,000 liability insurance stays in force and assigned to the contracting company. Let the insurance lapse and the renewal fee alone does not save the license.

Continuing education is where Ohio sources disagree in print. Some guides, quoting the statute's wording, still say ten hours a year. The board's own testimony and its current renewal practice both say eight hours for the one-year renewal, and 24 hours on the three-year cycle. We publish eight, the figure the board will actually check when your renewal comes due.

Half of those hours may be taken online: four of the eight on the annual cycle. Licensees stepping away from the trade can park the license in inactive escrow status instead of surrendering it. The $60 fee continues in escrow, but no education or insurance is required while parked. Reactivation asks for the missed education, capped at 30 hours, fresh insurance proof and, outside the renewal window, a $60 fee.

The other five trades: no state license, but not no rules

Five of the eight trades on this page have no Ohio state license at all. There is no state general contractor license, and no state license for roofing, painting, landscaping or carpentry. A website quoting an Ohio application fee or exam for any of them is inventing it, as this site's own templates did until the October 2026 verification removed them.

What governs them instead is local and contractual. Cities and counties license or register general and residential contractors on their own terms, and building departments enforce the Ohio Building Code and the Residential Code of Ohio through permits and inspections. A general contractor working three metro areas may hold three local registrations, each with its own renewal rhythm.

Since 2026 a state layer has been arriving underneath the residential side. House Bill 614 created Ohio's first statewide home improvement contractor registration, run by OCILB, for work on one-to-three-family homes, and it began phasing in during 2026. Per the published design it carries a background check, a $25,000 surety bond and $500,000 of liability cover. Confirm its current status with the Department of Commerce before relying on it.

What unlicensed commercial work actually risks

Inside OCILB's five trades, working commercially without the license is a criminal matter, not a fee problem. A first violation is a minor misdemeanor under section 4740.99 of the Revised Code, and later violations rise to a fourth-degree misdemeanor. Alongside the criminal side, the board can impose civil fines of up to $1,000 per violation per day under section 4740.16(B), after a hearing.
