How to get a contractor license in Ohio (2026)
Ohio requirements vary — some contractor types are licensed at the state level and others locally. Confirm with your Ohio state contractor licensing board.
- 1Meet the experience requirement
Most jurisdictions require documented hands-on construction experience (commonly ~2–4 years) before you can sit for a contractor exam. Gather references, W-2s, or project records that prove it.
- 2Pass the required exam(s)
Expect a trade/business-and-law exam. Study the adopted building code, business practices, and safety. Your local building department publishes the requirements.
- 3Get bonded and insured
You'll typically need a surety bond and general liability insurance (and workers' comp if you have employees). Amounts vary by state and license class.
- 4Register your business
Form your entity (LLC/corp), get an EIN, and register with the state. Keep it in good standing for renewals.
- 5Submit the application
File with your Ohio state contractor licensing board, pay the fees, and provide your experience, exam results, bond, and insurance. Approval times vary.
- 6Renew and stay compliant
Track renewal dates, continuing education (where required), and insurance/bond expirations so your license never lapses.
