Pennsylvania Plumbing License

Pennsylvania Plumbing License Requirements – Overview

Pennsylvania plumbing license requirements are set by the city or county, NOT the state.

In Pennsylvania, the plumber must be generally licensed even if working for a licensed Pennsylvania plumbing contractor.

For an overview of how U.S. Plumbing License Requirements work, refer back to the Plumbing License Requirements homepage.

The Rule:

Some of Pennsylvania’s 2,562 municipalities have established local licensure or certification requirements for contractors or construction trades people. Typically, these requirements pertain to home improvement contractors, electrical contractors (or electricians), and plumbing contractors (or plumbers). Since the Commonwealth has no jurisdiction in this matter, the Department maintains no records concerning municipalities that have established licensure or certification requirements. This information can only be obtained by contacting the municipality where construction work will occur.

In Plain English:

Local jurisdictions (counties, cities or towns) are responsible for setting their own Pennsylvania plumbing license requirements and issuing plumbing licenses.

  • Journeyman and Master Plumbers generally need a license, which allows them to work in the trade for a plumbing contractor.
  • Apprentices do not need a license in PA.

There are often reciprocity agreements in place between jurisdictions that will allow plumbers with Journeyman or Masters license issued in one city, county or township to work in another city, county or township upon proper notice and application.


Pennsylvania Plumbing Apprentice Programs

The programs offered by both the unions, as well as other entities, 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 some of the programs, the apprentice will receive academic credit for the training towards an Associate’s degree.

  • The program will last 4-5 years, depending on the program.
  • The apprentice will need to complete 2,000 of on the job paid training and 224 hours of classroom instruction, depending on the program.
  • Upon completion of the program, the apprentice plumber will be eligible to receive a Journeyman Plumber’s license.

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
  • Be able to legally work in the United States.

Some programs also require:

  • That the applicant be a citizen of the United States
  • Have a valid Pennsylvania drivers license
  • Be of “good moral character”
  • Take an entrance exam to be admitted into the program.
