PLUMBING x PENNSYLVANIA

Plumbing contractor requirements in Pennsylvania.

No Pennsylvania state agency licenses plumbers. HICPA § 12 preserves local plumber licensing conditioned on testing, and the two big systems are Philadelphia and Allegheny County. Residential plumbing over the $5,000-per-year threshold also requires HIC registration with the Attorney General.

Philadelphia's Master Plumber License requires at least one year as a registered Philadelphia Journeyman Plumber, the ICC-administered Philadelphia Master Plumber exam, and $500,000 / $300,000 / workers' comp insurance; it costs $303 initially and $253 a year. In Allegheny County the Health Department's Plumbing Program licenses apprentice, journeyman and master plumbers under its Article XV plumbing code, with exams twice a year and licenses renewed annually on the plumber's birthday.

LICENSE TRUTH
Pennsylvania has no state plumbing license; plumbers are licensed locally — Philadelphia by L&I and Allegheny County (including Pittsburgh) by the county Health Department — and residential work also needs HIC registration.
STATE ↔ LOCAL
HICPA § 12 preempts local registration or licensing of home improvement contractors — no municipality may charge a fee to register or license a HIC-registered contractor as such. Municipalities keep building permits, UCC enforcement, the § 302(e) workers' compensation check, pre-2006 local insurance standards, and pre-existing trade licenses conditioned on testing (electricians, plumbers and other trades).

§ 06 · Enforcement

What the law does about unlicensed plumbing work.

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.

§
HICPA § 8 (73 P.S. § 517.8)Statute

Home improvement fraud

Misleading inducements, taking an advance payment and not performing or refunding, concealing identity, posing as a government or utility employee, and similar acts are home improvement fraud. Amounts over $2,000 are a third-degree felony; the grade rises one step when the victim is 60 or older, and a second offense is a second-degree felony regardless of amount. The court may revoke or suspend the registration.

ConsequenceM1 → F3 → F2; registration revocation
§
HICPA §§ 9, 10; UTPCPL §§ 8(b), 9.2Statute

Unregistered work and other prohibited acts

Failing to register, abandoning a job without justification, or deviating from specifications without a signed change order is a prohibited act — and any HICPA violation is a violation of the Unfair Trade Practices and Consumer Protection Law, which carries Commonwealth civil penalties for willful violations and private suits for actual damages or $100, with up to treble damages.

ConsequenceUp to $1,000 per violation ($3,000 if victim is 60+)
§
HICPA § 7(a), (g)Statute

Unenforceable contract

A home improvement contract that misses HICPA's written-contract requirements is not valid or enforceable against the owner; recovery is limited to the reasonable value of requested work where a court finds it equitable.

ConsequenceContract unenforceable against owner
§ 08 · Pennsylvania FAQ

Questions plumbing contractors ask about Pennsylvania.

Q01Does Pennsylvania have a state contractor license?+
No. Pennsylvania licenses no general, roofing, electrical, plumbing or HVAC contractors at the state level. The statewide requirement for residential work is Home Improvement Contractor registration with the Attorney General — a $100 two-year registration with $50,000 / $50,000 insurance minimums, not a skills exam.
Q02Who is exempt from HIC registration?+
A person whose home improvements totaled less than $5,000 in the previous taxable year, and home improvement retailers with net worth over $50 million (their installers must still register). The Act also does not cover new home construction or the conversion of commercial structures into residences.
Q03Does Pennsylvania license plumbers statewide?+
No. Plumbers are licensed by local authorities — Philadelphia L&I and the Allegheny County Health Department are the largest. HICPA § 12 preserves these testing-based local licenses.
Q04Who licenses plumbers in Pittsburgh?+
The Allegheny County Health Department Plumbing Program, which issues apprentice, journeyman and master licenses renewed annually on the plumber's birthday.

Pending verification: HIC registration fee: the Attorney General's FAQ and portal state $100 per two-year registration, but HICPA § 5 as published on palegis.us still reads $50 — the amending authority for the increase was not located · Which model-code editions the UCC triennial update approved October 16, 2025 (effective January 1, 2026) adopts was not confirmed in regulation text · Licensing in Pennsylvania's other ~2,500 municipalities was not surveyed; HICPA § 12 preserves pre-existing local trade licenses conditioned on testing, so a borough or township may still license a trade · Allegheny County plumber license fees and experience-hour minimums, and the rule that only registered master plumbers may obtain plumbing permits, were not confirmed on an ACHD page
