Ohio Plumbing License

Ohio Plumbing License Requirements – Overview

Ohio plumbing license requirements for individual plumbers are set by, and licenses are issued by, the town, city or county in which the plumber will work, NOT by the state.  The only license the state issues is the Ohio commercial plumbing contractor licenses.

In Ohio, the plumber must be licensed even if working for a plumbing contractor who has a Ohio commercial plumbing contractor license.  For more information abou the ohio commercial contractor license for plumbing, see the state website here.

Ohio Plumbing Apprentice Programs

There are a variety of union and non-union apprentice training programs offered throughout the state of Ohio in conjunction with various technical schools, plumbing contractors, unions and the Ohio Bureau of Employment Services / Ohio State Apprenticeship Council. See the list of registered apprenticeship programs here (this shows all trades, so search down the right-hand column for plumbing).

As an example, one such program, the APHC Apprenticeship Program offers a 4 year non-union apprenticeship where the apprentice receives 576 hours of classroom training, as well as 8,000 of on the job training.

The programs provide a mixture of on the job training in the field, as well as classes that are offered during nights and weekends in formal classroom settings.  All apprentice programs require a significant amount of independent study outside of the classroom.

In general, applicants must be:

  • at least 18 years old,
  • possess either a high school diploma or G.E.D.,
  • be physically capable of working on a construction site, and
  • be able to legally work in the United States.

Upon successful completion of the program, the apprentice will be eligible to apply for a local Journeyman plumbing license.

Ohio Plumbing License Requirements

The individual counties and cities in Ohio issue plumbing licenses to individual plumbers.  The state only issues the Ohio commercial plumbing contractor license.

Requirements are generally as follows:

  • Apprentice Plumber:

There is no requirement for a license, but jurisdictions require that apprentices be registered in the jurisdiction that they are working in.


  • Journey (Journeyman) Plumber:

1.  Be at least 18 years old.

2.  Pay the required fees for the license, which vary from $50-$185.

3.  Have taken and passed a local licensing examination for Journeyman Plumber demonstrating sufficient knowledge of the plumbing trade.

4.  Depending upon the jurisdiction, demonstrate at least 3-5 years of experience in the trade or the completion of a United States Department of Labor, Bureau of Apprenticeship Training (USDOL, BAT) certified plumbing apprenticeship program.  The candidate for licensing must provide evidence of relevant experience in the form of W-2s from a plumbing contractor or a certificate of completion of a qualified apprentice program.

  • Master Plumber:

There is no Master Plumber designation in a majority of the counties and cities within Ohio.  The ones that do have a Master Plumber designation are referring to the commercial plumbing contractor’s state license and not to a local-specific Master Plumbing license.
