In the state of Ohio, there are no statewide licensing requirements for general or residential plumbers, but the licensure occurs at the local level.

Commercial plumbers must be licensed by the Ohio Construction Industry Licensing Board (OCILB) before they can work as plumbers.

Ohio Plumbing License Reciprocity

It is worth mentioning that, according to the Ohio Division of Industrial Compliance, the state of Ohio maintains reciprocity agreements for plumbers with the following three states:

  • South Carolina
  • Tennessee
  • West Virginia

This means that individuals already licensed in one of these states can begin working as plumbers in Ohio, or vice versa.

If they get the approval, they must take and pass the exam, and only then they will be issued a license.

The application form needs to be completely filled out, notarized, and free or errors before submission.

Additionally, they must successfully pass both a federal and state background check.
