Pennsylvania Plumber License Requirements

Pennsylvania does not issue a statewide journeyman or master plumber credential. The Uniform Construction Code is largely administered locally, so the credential, examination, insurance, permit, and renewal rules depend on where the work is performed. Philadelphia licenses Master Plumbers, while the Allegheny County Health Department administers apprentice, journeyman, and master plumbing licenses. A contractor performing at least $5,000 of covered home improvements in a year must also register with the Pennsylvania Attorney General under the Home Improvement Consumer Protection Act (HICPA). That registration is consumer-protection registration, not a plumbing competency license.

Regulatory Body

Pennsylvania local code and licensing authorities (PA local authorities) administers the credential or scope-specific rules discussed here under Pennsylvania Construction Code Act and 34 Pa. Code Chapters 401–405; Home Improvement Consumer Protection Act. Whether that pathway applies depends on the work scope and conditions explained below. The Commonwealth establishes the UCC framework and HIC registration. Municipalities and local agencies administer permits and may impose plumbing-license requirements.

Eligibility Requirements

Applicants must be at least 18 years old. Check the current application for identification and tax-number requirements. There is no statewide plumber-license residency rule. Check the selected city or county application; HICPA registration also applies to out-of-state contractors performing covered work in Pennsylvania.

Good moral character

Do not assume a statewide plumbing character or background-screening requirement. Follow the application and disclosure instructions of the local licensing authority.

Background investigation

Local requirements vary; Philadelphia and Allegheny County publish their own application materials and review processes.

Experience and Education

The experience bar is 1 year of Philadelphia Master Plumber applicants must have held a Philadelphia Journeyman Plumber license for at least one year, or a comparable authorization from another jurisdiction subject to L&I approval. In Allegheny County, the journeyman route requires four years of employment under a registered master (and 576 hours of school); master applicants need two full years as a journeyman., and it must be backed by verifiable records — typically payroll, tax, project, or supervisor documentation covering the claimed period.

Accepted proof of experience or eligibility

Philadelphia: current or qualifying comparable journeyman authorization and master-exam pass record
Allegheny County: employment and schooling records for the journeyman route
Allegheny County: evidence of two full years as a journeyman for the master route
Philadelphia business and tax-registration materials when operating as a business

Education substitution

Allegheny County’s published journeyman route includes 576 hours of schooling and four years of employment. Philadelphia’s published master route is based on qualifying journeyman authority; ask L&I before relying on an out-of-jurisdiction credential.

Exam Requirements

Testing provider or authority: Philadelphia requires the ICC-administered Philadelphia Master Plumber examination. Allegheny County’s Health Department Plumbing Program administers its local journeyman and master examinations twice yearly.. The following examination requirements cover the pathways described in this guide; follow each part's classification, waiver, and local-scope conditions. Unpublished format details do not remove an examination requirement:

Philadelphia Master Plumber examination (ICC) — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin
Allegheny County Master Plumber examination — question count: confirm with the authority, timing: confirm with the authority, passing score: confirm in the current candidate bulletin

Examination fee: Philadelphia’s Master Plumber service page does not list an examination fee. Allegheny County lists a $265 Master Plumber examination fee and a $133 Journeyman examination fee; verify the current schedule before applying.

Retake policy: Use the current local application and examination instructions. Pennsylvania has no statewide plumbing examination or statewide retake rule.

Insurance and Bonds

There is no statewide surety bond tied to this credential in the cited record. Bonding can still surface at the project level — permit, license, or public-works bonds — so check before you bid.

General liability

For a Philadelphia Master Plumber license, L&I requires at least $500,000 general liability per occurrence. HIC registrants performing covered residential work need at least $50,000 personal-injury liability and $50,000 property-damage liability.

Workers' compensation

Philadelphia’s Master Plumber service page requires workers’ compensation coverage of $100,000 per accident, $100,000 per employee, and $500,000 per policy. Requirements elsewhere are local and can differ.

Additional financial requirements

No statewide plumbing-license financial-statement requirement was identified.

Renewal and Continuing Education

The Pennsylvania Plumber — Local Licensing; No Statewide Trade License runs on a year renewal cycle. The current renewal fee is $253. The listed $253 renewal is Philadelphia’s Master Plumber fee. Allegheny County lists $375 for annual Master Plumber renewal; both must be checked against the live local schedule.

Continuing education: The Philadelphia Master Plumber service page lists annual renewal but does not state a continuing-education requirement. Allegheny County licenses renew annually on the licensee’s birthday; check the current local instructions for any CE changes.

Reciprocity

For this classification, Pennsylvania does not recognize the NASCLA Accredited Examination.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

There is no statewide plumbing license to reciprocate. Philadelphia may consider comparable authorization from another state or local jurisdiction for its one-year journeyman prerequisite, subject to L&I approval; that is not blanket reciprocity. Confirm each local authority’s current policy.

Step-by-Step Application Roadmap

Identify the permit and licensing authority. Start with the municipality or local code agency for every location where permits will be pulled; Pennsylvania has no statewide plumbing credential.
Choose the applicable local pathway. Philadelphia requires a Master Plumber license for plumbing work. Allegheny County operates separate apprentice, journeyman, and master levels.
Document qualifying experience. Philadelphia requires at least one year as a Philadelphia journeyman or qualifying comparable authority. Allegheny County has its own employment, schooling, and journeyman requirements.
Pass the local examination. Philadelphia uses the ICC Master Plumber exam. Allegheny County schedules its local examinations through the Health Department.
Meet insurance and business requirements. Philadelphia Master Plumber applicants need the stated insurance, a Commercial Activity License, and tax compliance. Covered residential contractors also need HICPA registration.
Apply for permits through the local authority. Keep the individual or business credential active and meet the locality’s permit, insurance, and renewal conditions.

Application Checklist

Before submitting to PA local authorities, the applicant should have each of the following ready:

Confirm the plumbing license and permit rule for each municipality or local agency
Philadelphia: qualifying journeyman authority, ICC exam, Commercial Activity License, tax compliance, and required insurance
Allegheny County: applicable apprentice/journeyman/master experience, school, examination, and annual-renewal materials
PA HIC registration and $50,000/$50,000 liability coverage for covered residential work at or above $5,000 annually
Local permit application and current certificate of insurance

Common Filing Mistakes

The errors below are the ones that most frequently cost Pennsylvania Plumber applicants time, drawn from the cited board guidance.

Treating a city license as statewide

A Philadelphia or Allegheny County license does not create statewide authority. Confirm the rule wherever the permit will be issued.

Confusing HIC registration with competency licensing

HICPA registration does not replace a required city or county plumbing credential.

Using unsupported exam details

Local examination formats and reference editions can change. Follow the current Philadelphia ICC or Allegheny County notice instead of relying on old candidate guides.

Ignoring city business and insurance requirements

Philadelphia’s Master Plumber path includes business, tax, and insurance documentation beyond the trade exam.

Missing annual local renewal

Philadelphia and Allegheny County both use annual renewal; the requirements and fees are not interchangeable.

Study and Reference Materials

The list below collects the board's cited references and the materials applicants typically study from. CLR is not paid to recommend any of them.

Philadelphia Master Plumber licensing materials — City of Philadelphia L&I. Use the current ICC examination and city application instructions.
Allegheny County Plumbing Program licensing information — Allegheny County Health Department. Lists the County’s local experience, school, examination, and fee requirements.
Pennsylvania UCC resources — PA Department of Labor & Industry. Use the local-enforcement resources to identify the code agency for the job location.
