Where a Pennsylvania master plumber license transfers

How local licensing works. With no state plumbing board, each Pennsylvania city that licenses master plumbers does so under its own ordinance. The journeyman card, where it exists, does not authorize pulling permits or running a shop; the master (or master-contractor) license does. A master license is valid only in the issuing city. The journeyman page states that a journeyman works 'under a licensed master plumber' and may not operate a business, which implies the master license is the contracting credential. Other PLI trade licenses are issued to individuals, expire 365 days from issue, and (for electrical and mechanical) accept ICC master exams for any code year plus a stated experience total; whether plumbing follows that pattern is unverified. 2025 plumbing license fee unknown.

Allentown. 2026 Master Plumber Exam Application is posted under Professional Trades Licensing. Contracting requires the trades license and a city business license. Reciprocity not mentioned on the landing page. Electrical Option B on that same form (eight years in lieu of exam) must not be assumed to apply to plumbing.

Inbound master. No Pennsylvania state license and no verified exam-waiver reciprocity. Plan on a new application in each city where permits will be pulled. Philadelphia is the most fully documented shop: obtain the Master Plumber's License after (typically) holding or qualifying beyond the journeyman ICC path; confirm current master fees and exam on the master service page before applying. Allentown requires its master plumber exam application plus a business license. Scranton uses the 2021 master contractor packet. Statewide reciprocity: none.
