Who can legally do this in Ohio
The Ohio Construction Industry Licensing Board issues state licenses to commercial contractors in plumbing. Applicants must pass an exam, carry at least $500,000 in contractor liability coverage, and generally have 5 years as a tradesperson. This is a commercial license, so it doesn't settle what work on your home requires. Ask your local building department.
