Pennsylvania to New Hampshire: journeyman plumber license reciprocity
Pennsylvania does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is New Hampshire's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Traditional application and New Hampshire plumbing examination (non-qualifying jurisdictions)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An out-of-state journeyman whose origin is not on OPLC's Plc 313.34 qualifying-jurisdiction list cannot use endorsement and applies through the traditional Mechanical Licensing Board process. Under Mec 302.12 and Mec 305.01(b)(4), proof of journeyman plumber licensure in another state or jurisdiction that licenses plumbers makes the applicant eligible for the New Hampshire journeyman exam in place of the New Hampshire apprenticeship, 600 hours of education and 8,000 hours of experience; the exam itself is not waived and must be passed with at least 70 percent. After passing, the applicant mails the paper application with the $198 two-year journeyman plumber fee (Plc 1002.25). Plc 313.11 lets an individual from a non-listed jurisdiction request a waiver of endorsement criteria based on education, training and experience, and OPLC's reciprocity FAQs allow a written request under Plc 210.03 to reconsider whether a jurisdiction is substantially similar.
Journeymen licensed in one of the 34 jurisdictions OPLC lists for journeyman plumber under Plc 313.34 on its New Changes for Reciprocity page may apply by endorsement instead, without the New Hampshire exam, provided the license is active and unencumbered.

How New Hampshire licenses journeyman plumbers
New Hampshire journeyman plumber · “Journeyman Plumber”
Statewide license
Issued by New Hampshire Mechanical Licensing Board, Office of Professional Licensure and Certification (OPLC)
New Hampshire issues a statewide Journeyman Plumber license through the Mechanical Licensing Board in the Office of Professional Licensure and Certification (OPLC). The same board licenses trainee/apprentice plumbers, master plumbers and mechanical business entities, and also regulates fuel gas fitters; it does not license HVAC technicians. The published two-year journeyman plumber fee is $198 (OPLC Mechanical Safety and Licensing Board fee table; Plc 1002.25). Since 3 May 2024, out-of-state journeymen from jurisdictions OPLC has determined substantially similar under RSA 310:17 and Plc 313.34 may be licensed by endorsement without the New Hampshire exam; Plc 313.34 treats a comparable journeyman path as a four-year apprenticeship with 560 instruction hours plus an exam, and the origin code must be the same or a later edition of New Hampshire's building and fire codes. Everyone else uses the traditional route: Mec 302.12 makes an out-of-state plumber license sufficient to sit the New Hampshire plumbing examination (given by Prov); the exam itself is not waived.
Why Pennsylvania has nothing to transfer
Pennsylvania journeyman plumber · “Journeyman Plumber (city-issued; no state license)”
Licensed by cities and counties
Pennsylvania has no statewide plumber license at the journeyman level: none of the Department of State's 29 professional licensing boards covers plumbers or plumbing contractors (the only construction-related board is Crane Operators), and there is no Commonwealth journeyman or master plumber credential. Individual licensing exists only where a city ordinance creates it. Philadelphia's Department of Licenses and Inspections, advised by the Plumbing Advisory Board, issues a Journeyman Plumber License (Philadelphia Code Title 9-1003) that authorizes plumbing work under a licensed master plumber but not running a business: four years as a Philadelphia-registered apprentice (or a similar authorization from another state or local jurisdiction with equal or greater requirements, subject to L&I approval), the ICC Journeyman Plumber Examination referencing the current Philadelphia Code or applied within 12 months of passing, and a $126 annual fee ($25 of that is the non-refundable application fee). Allentown posts 2026 journeyman and master plumber exam applications and licenses the plumbing trade separately from a business license. Scranton's published form is a master electrical/mechanical/plumbing/general contractor application with no journeyman plumber form on that page. There is no state-level reciprocity; Philadelphia's other-jurisdiction clause substitutes for local apprentice registration only and does not waive the ICC exam.
How local licensing works in Pennsylvania
How local licensing works. Pennsylvania does not license plumbers. Each city that licenses the trade does so under its own ordinance through L&I, a plumbing board, or a codes office. Residential plumbing contractors doing $5,000 or more of home-improvement work in a year must also register with the Pennsylvania Attorney General under the Home Improvement Consumer Protection Act; that registration is not a trade license and involves no exam.
Philadelphia (verified). L&I issues Plumber Apprentice, Journeyman Plumber and Master Plumber licenses (trade-license list). The journeyman page, last updated with the Plumbing Advisory Board, is the only plumbing service page opened in full. Scope: drainage, cesspools, traps, waste vents, water piping, and fixtures attached to plumbing elements, excluding gas or electric heaters; work must be under a licensed master plumber; the card does not authorize operating a business. Experience: registered Philadelphia apprentice for a minimum of four years, or proof of a similar authorization from any other state or local jurisdiction with equal or greater qualification requirements, subject to L&I approval. Exam: ICC Journeyman Plumber Examination; must reference the current Philadelphia Code and associated standards, or the application must be filed within 12 months of passing. Photo: 2 in. × 2 in. color. Fees: $126 license ($25 non-refundable application fee applied to that amount; balance due on approval); $126 annual renewal; 1.5% of the license fee per month if more than 60 days late. Apply via eCLIPSE or in person at 1401 JFK Blvd. (Permit and License Center). PLI issues person-held trade licenses in other trades; plumbing exam, fee, experience and whether a journeyman tier exists were not verified. Do not assume Pittsburgh waives a plumber exam.
Allentown. Building Standards and Safety licenses electrical, plumbing and sheet metal trades. Operating a contracting company requires both a trades license and a city business license. No reciprocity language appears on the trades-licensing page. In Philadelphia, document four years (local apprentice or equivalent out-of-jurisdiction authorization) and pass the ICC Journeyman Plumber Examination on the Philadelphia Code (or apply within 12 months of that exam). Elsewhere, expect a separate city application and usually a local or ICC exam. Statewide reciprocity: none.
