Pennsylvania to Kentucky: journeyman plumber license reciprocity
Pennsylvania does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Kentucky'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.
Out-of-state journeyman plumber (Kentucky examination; apprentice experience credited)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Kentucky publishes no plumbing reciprocity or endorsement path that waives the journeyman exam. Under 815 KAR 20:030 Section 3, every journeyman applicant — including a person already licensed elsewhere — qualifies by two consecutive years as an apprentice plumber, or by a department-approved course on the practice of plumbing or the Kentucky State Plumbing Code plus one year as an apprentice, then must pass each portion of the Kentucky journeyman plumber examination with at least 75 percent (written questions on plumbing principles, KRS Chapter 318 and 815 KAR Chapters 2 and 20; a pipe-sizing drawing; and a practical installation section for which the applicant furnishes materials). The regulation does not limit apprentice experience to Kentucky, so documented out-of-state apprentice time is the credit an inbound journeyman receives; it does not list an out-of-state journeyman license as a substitute for that experience. Register on Form PLB-3 ($50 exam fee, passport photo), then file Form PLB-2 with the $60 license fee (prorated 7–18 months to the birth month). Passing scores are valid three years. Failed portions may be retaken within one year of first notice for the full $50 each time. There is no separate law or business exam.
No hour-per-year conversion is published in 815 KAR 20:030 (HVAC uses 1,500 hours and electrical 1,600 in other KAR chapters; do not assume either figure for plumbing). Whether a city- or county-issued origin license helps is not addressed; Section 2's out-of-state master path requires a license 'issued by another state,' so municipal origin licenses are treated as not accepted. The written exam includes KRS 318 and 815 KAR Chapter 20, so Kentucky law is tested inside the trade exam rather than as a separate LawCodeExam. No Prov/PSI plumbing bulletin was found; exams are department-administered quarterly.

How Kentucky licenses journeyman plumbers
Kentucky journeyman plumber · “Journeyman Plumber”
Statewide license
Issued by Kentucky Department of Housing, Buildings and Construction (DHBC), Division of Plumbing
Kentucky issues a statewide Journeyman Plumber license through the Department of Housing, Buildings and Construction, Division of Plumbing, under KRS Chapter 318 and 815 KAR 20:030. A new applicant must have either two consecutive years as an apprentice plumber or a department-approved plumbing / Kentucky State Plumbing Code course plus one year as an apprentice, pass every portion of the department-administered Kentucky journeyman plumber examination (written, drawing, and practical) with at least 75 percent, file Form PLB-2 with a $60 license fee prorated to seven to eighteen months ending on the birth month, and register for the exam on Form PLB-3 ($50, passport photo). Exams run in February, May, August and November. Licenses renew annually at $60 with six hours of continuing education under 815 KAR 2:010 (waived for the first renewal if the initial license issued within twelve months of renewal). 815 KAR 20:030 does not waive the Kentucky exam for out-of-state journeymen, does not use the word reciprocity, and names no partner states; an inbound journeyman documents apprentice-level experience and sits the Kentucky exam.
Why Pennsylvania has nothing to transfer
Pennsylvania journeyman plumber · “Journeyman Plumber (city-issued; no state licence)”
Licensed by cities and counties
Pennsylvania has no statewide plumber licence 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 authorises plumbing work under a licensed master plumber but not running a business: four years as a Philadelphia-registered apprentice (or a similar authorisation 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 licence. 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 licence and involves no exam.
Philadelphia (verified). L&I issues Plumber Apprentice, Journeyman Plumber and Master Plumber licences (trade-licence 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 authorise operating a business. Experience: registered Philadelphia apprentice for a minimum of four years, or proof of a similar authorisation 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. colour. Fees: $126 licence ($25 non-refundable application fee applied to that amount; balance due on approval); $126 annual renewal; 1.5% of the licence 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 licences 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 licence and a city business licence. No reciprocity language appears on the trades-licensing page. In Philadelphia, document four years (local apprentice or equivalent out-of-jurisdiction authorisation) 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.
