How Ohio licenses plumbers
Licensing is split between the state and local governments.
Who licenses: Ohio Construction Industry Licensing Board (Ohio Department of Commerce)
License types: Plumbing Contractor.
Businesses: The Ohio Construction Industry Licensing Board licenses commercial plumbing contractors; residential plumbing contractors are regulated by local building and health departments.
Local rules: The state license is for commercial work; local building and health departments register residential plumbing contractors and may require the state license for them.
Check a license: elicense4.com.ohio.gov
Ask your city or county building or health department what registration it requires for residential plumbers, and check whether the contractor also holds an Ohio state plumbing contractor license.
We could not confirm every detail from Ohio’s own sources, so treat this as a starting point and check with the agency.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – water heaters, repiping and sewer lines often do.
