Like New York, Pennsylvania has no single statewide plumbing license. To get a plumbing license in Pennsylvania, you license with the city or municipality where you work, not one central state agency.
How plumbing licensing works in Pennsylvania
The Pennsylvania Department of Labor & Industry enforces the statewide Uniform Construction Code (UCC), which sets the building standard your work must meet. But the license to perform plumbing work is issued locally, so requirements and license types vary by town.
Philadelphia and Pittsburgh
The bigger cities run the most formal programs. The City of Philadelphia Department of Licenses & Inspections (L&I) issues the Master Plumber license required to pull plumbing permits inside city limits. Pittsburgh and Allegheny County run their own licensing. A Philadelphia license carries no automatic standing in Allegheny County or Erie, and there is no reciprocity between Pennsylvania municipalities.
Smaller towns
Many smaller municipalities have lighter requirements or rely on the UCC and permit process rather than a formal plumber license. Always confirm with the local code or licensing office before you bid work there.
The basic path
Pick where you will work, contact that municipality licensing office, meet their experience and exam rules, and get licensed there. If you work across city lines, plan on more than one license since PA does not share reciprocity between towns.
