Plumber licensing in Pennsylvania

No Statewide License

Pennsylvania does not issue a statewide plumber license. Plumber licensing is delegated to individual municipalities and counties, while statewide consumer-protection rules are layered on top via the Home Improvement Contractor (HIC) registration administered by the PA Office of Attorney General.

PHILADELPHIA MASTER PLUMBER (L&I). The City of Philadelphia issues Master Plumber licenses through the Department of Licenses & Inspections (L&I). Applicants must be registered as a Philadelphia Journeyman Plumber for at least one year before applying, and the underlying Journeyman credential itself requires four years as a registered Philadelphia apprentice plumber. The Master Plumber exam is administered by the International Code Council (ICC) against the current Philadelphia Code; applications must be filed within 12 months of passing. Initial license fee is $303 (including a $50 non-refundable application fee); annual renewal is $253 with a 1.5%-per-month late penalty after the 60-day grace period. Required insurance minimums: $500,000 general liability per occurrence, $300,000 auto liability, and workers' comp at $100,000 per accident / $100,000 per employee / $500,000 policy limit.

Allegheny County Plumbing Board

Allegheny County, which includes the City of Pittsburgh, licenses plumbers through the Allegheny County Health Department (ACHD) Plumbing Program under Article XV of the county code. Only Registered Master Plumbers may pull plumbing permits in the county. The journeyman path requires 576 classroom hours plus 8,000 field hours under an Allegheny County Registered Master Plumber, and master applicants typically must complete two additional years as a journeyman before sitting for the master exam.

Other Cities

Smaller PA municipalities set their own rules, and many defer to the PA Uniform Construction Code for inspection while requiring a local business-license or contractor-registration filing. A Philadelphia Master Plumber license is not automatically recognized in Allegheny County, and vice versa; plumbers working across jurisdictions typically maintain separate local credentials. Verify locally before bidding.

Pa HIC Statewide

Any contractor performing residential home-improvement work totaling at least $5,000 in a calendar year must register as a Home Improvement Contractor (HIC) with the PA Office of Attorney General under the Home Improvement Consumer Protection Act (HICPA, 73 P.S. Section 517.1 et seq.). The registration fee rises to $100 every two years for applications submitted after March 2, 2026. The HIC number must appear on contracts and advertisements.

Union Pathway

United Association (UA) locals run registered apprenticeships that stack with municipal credential paths. UA Local 690 covers the Philadelphia area and administers an apprenticeship feeding the Philadelphia Journeyman exam; UA Local 27 covers Pittsburgh and Western PA and coordinates with the Allegheny County program. Non-union merit-shop apprenticeships (for example, ABC Keystone) also qualify graduates to sit for local exams. Both paths are recognized by Pennsylvania municipalities; choice depends on employer, wage structure, and benefit preference.

Verification Advice

Before accepting work, confirm (1) which municipality has jurisdiction over the job site, (2) whether a local plumber license is required there, (3) whether the work triggers HIC registration, and (4) that insurance meets the local minimums. Municipal rules change; the source URLs above are primary and should be re-checked before applying.
