Ohio has no statewide general contractor or home-builder license, so for most building trades your insurance requirements come from your city or county and from your clients, not a state board. The exception is five commercial trades, electrical, HVAC, refrigeration, plumbing, and hydronics, which are licensed by the Ohio Construction Industry Licensing Board (OCILB) and must carry contractor liability insurance to hold the license.
Who this is for: Ohio contractors sorting out what insurance a license requires, and how workers' comp fits alongside it.
The short version
- There is no statewide general contractor or home-builder license in Ohio; local registration and client contracts drive most requirements.
- OCILB licenses five commercial trades and requires contractor liability insurance, not workers' comp, to hold the license.
- The OCILB liability minimum is 500,000 dollars, with the board named on the certificate and the coverage kept in force for the life of the license.
- Workers' comp is still required separately from BWC once you have employees, and OCILB tracks that same mandate.
- The 500,000-dollar figure is a general liability requirement, not a workers' comp limit; the two are different coverages.
License insurance versus workers comp
These are two different requirements that people often blur together. The OCILB license requires general liability, which covers injury to other people or damage to their property caused by your work. Workers' comp is separate: it covers your own employees' on-the-job injuries and comes only from BWC. A licensed electrician with employees needs both, and letting the liability certificate lapse can suspend the license.
| Requirement | What it covers | Where it comes from |
|---|---|---|
| OCILB contractor liability (5 trades) | Injury to others or damage to their property from your work | A private carrier, minimum 500,000 dollars |
| Workers' compensation | Your own employees' on-the-job injuries | Only the Ohio Bureau of Workers' Compensation |
| Stop-gap employer's liability | A direct lawsuit by an injured worker | A private carrier, added to liability or a package |
| Local registration (general contractors) | Varies by city or county | Your local building authority |
What the OCILB license expects
To hold an OCILB license in one of the five trades, you carry at least 500,000 dollars of contractor liability insurance, name OCILB as the certificate holder, and keep the coverage in force for the life of the license, since a lapse triggers suspension. Board minimums can change, so confirm the current figure on the live OCILB application before you rely on it. Workers' comp is layered on top: OCILB expects it once you have employees, which simply tracks the Ohio requirement to carry BWC coverage.
A Columbus example
Illustrative, not a quote. A Columbus electrician applies for an OCILB license and lines up a general liability policy of at least 500,000 dollars with OCILB named on the certificate. Because she has two employees, she also opens BWC workers' comp coverage, which OCILB expects and Ohio requires. She adds a private stop-gap employer's liability policy so she is protected if a worker is hurt and sues directly. We help her keep the liability certificate active so the license does not lapse, and make sure the BWC payroll is reported correctly.
Real questions Ohio owners ask
Does Ohio have a statewide contractor license?
Not a general one. Ohio has no statewide general contractor or home-builder license. Local cities and counties handle registration for general and residential work, so your requirements often come from them and from your clients.
Which trades need a state license in Ohio?
Five commercial trades: electrical, HVAC, refrigeration, plumbing, and hydronics. These are licensed by the Ohio Construction Industry Licensing Board, and each licensed contractor must carry contractor liability insurance to hold the license.
How much insurance does an OCILB license require?
At least 500,000 dollars of contractor liability insurance, with OCILB named as the certificate holder and the coverage kept in force for the life of the license. Confirm the current minimum on the OCILB application, since board minimums can change.
Is that 500,000 dollars a workers comp requirement?
No. The 500,000-dollar minimum is a general liability requirement, which covers injury to others or damage to their property. Workers comp is a separate coverage for your own employees and comes only from BWC.
Do I need workers comp on top of the license insurance?
Yes, once you have employees. Workers comp is required from BWC whenever you have one or more employees, and OCILB expects it too. The license liability policy does not cover your own workers' injuries.
What happens if my liability certificate lapses?
Letting the OCILB liability coverage lapse can suspend your license, because the board requires it in force for the life of the license. Keeping the certificate active with OCILB named as certificate holder is part of staying licensed.
Do general contractors in Ohio need a state license?
No. General contractors are not licensed by the state, though many cities and counties require local registration. A general contractor with employees still needs BWC workers comp and usually carries general liability by contract.
Why Ohio owners choose Morrow
- We shop the right market for you. In Ohio, workers' comp is sold only by the state-run Ohio Bureau of Workers' Compensation (BWC), so we handle your BWC enrollment and payroll classifications and place the private stop-gap employer's liability and other-states coverage the state fund does not include.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
