How to get a contractor license in Ohio: HVAC, plumbing and electrical through OCILB
Ohio uses a split system: part state, part local. Statewide licensing covers commercial specialty trades only (electrical, HVAC, plumbing, hydronics, refrigeration) through OCILB with exams administered by Prov, while general contractor licensing or registration is handled by local building departments and municipalities.

Start at the source
Ohio Construction Industry Licensing Board (Ohio Department of Commerce, Division of Industrial Compliance) is the official authority. Its site, com.ohio.gov, carries the current requirements, applications and any candidate bulletin. Everything on this page routes back to it, because requirements change and the agency's version is the one that counts.
The path, wherever you are
- Confirm the licensing level above with the authority, then pull the current application checklist from its site.
- Where a trade exam is required, get the candidate bulletin: it names the exam vendor, the topics, and the exact reference editions allowed on the table.
- Buy the referenced code books in the exact editions listed, and tab them yourself within whatever marking the bulletin permits.
- Train the lookup, not just the knowledge: contractor trade exams are commonly open book, which makes finding the governing section fast the actual tested skill.
- Expect a separate business and law exam in many jurisdictions, with its own reference book.
Why open book changes your prep
An open-book exam gives you the answers and takes away the time to find them. The candidates who fail are rarely the ones who knew the least; they are the ones who found things slowest. That lookup skill is what this site trains:the free timed drill shows you your seconds-per-lookup in two minutes.

Frequently asked questions
How do I get an Ohio HVAC license?
Apply to the Ohio Construction Industry Licensing Board with proof of the trade experience OCILB requires, get approved to test, pass the Prov HVAC trade exam and the business and law exam, then complete the license application with insurance. The license is statewide and renews annually with continuing education.
How do I get an Ohio plumbing license?
The same OCILB route as HVAC: experience review, approval to test, the Prov plumbing trade exam plus business and law, then the application. Journeyman plumbers who are not contracting on their own do not need the OCILB contractor license; cities may license them locally.
What are the Ohio general contractor license requirements?
