Pennsylvania to Iowa: journeyman plumber license reciprocity
Pennsylvania does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Iowa'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 (all states except South Dakota): Iowa exam required; licensure by verification for Iowa residents
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Iowa has no plumbing reciprocity agreement with any state other than South Dakota, so a journeyman plumber from any other state must pass the Iowa journeyperson plumbing exam. An applicant who has established Iowa residency may apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4: the origin state sends a verification form directly to the board confirming the license is in good standing and was earned by meeting that state's experience requirements and exam, and the applicant supplies proof of residency and a criminal history statement; the board nevertheless requires proof of passing the applicable Iowa licensing exam and may issue a temporary license in the meantime. A non-resident applies through the ordinary exam route: the $35 Exam Approval Application, the Kirkwood-administered journeyperson plumbing exam ($119 per attempt, 75% to pass, approval valid one year), then the post-examination licensure application and a prorated three-year license fee ($180 for a full term). Exam eligibility on DIAL's page is either the U.S. DOL apprenticeship certificate of completion or a master-level plumbing license from another jurisdiction; a journeyman license alone is not listed as a substitute for the apprenticeship. An Iowa resident arriving from a jurisdiction that did not license plumbers may substitute three years of full-time plumbing work in the last four years under 481 IAC 430.5 and must still pass the exam.
The exam fee is set by Kirkwood Community College ($119 per attempt on Kirkwood's page; DIAL's license pages still show older figures of $99 and $95). DIAL's journey page lists an out-of-state master license as an alternative to the apprenticeship and offers a 'Journey by Master' application, but Iowa Code 105.18 requires every journeyperson to pass the state exam, so this path treats the exam as required; ask the board whether your master license lets you skip it. The board's published materials do not say whether an out-of-state journeyman license without a DOL apprenticeship certificate satisfies the apprenticeship requirement for a non-resident. DIAL publishes up to two weeks for exam approval and up to six weeks for application review, not counting exam scheduling.

How Iowa licenses journeyman plumbers
Iowa journeyman plumber · “Journeyperson Plumber”
Statewide license
Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)
Iowa issues a statewide, person-held Journeyperson Plumber license through the Plumbing and Mechanical Systems Board (PMSB), now part of the Department of Inspections, Appeals, and Licensing (DIAL); Iowa Code 105.17 preempts all city and county plumber licensing. A journeyperson works under the supervision of a master plumber. A new applicant must be 18, disclose any criminal convictions, complete four years as an apprentice in a U.S. Department of Labor-registered apprenticeship, and pass the Iowa journeyperson plumbing exam, which is approved by the board ($35 application) and administered through Kirkwood Community College ($119 per attempt, 75% to pass). Iowa's only reciprocity agreement is with the South Dakota State Plumbing Commission (May 2016) and covers journeyperson and master plumbers licensed by written examination; every other out-of-state journeyman must pass the Iowa exam, although a master plumber licensed in another jurisdiction may qualify for the Iowa journey license without the apprenticeship. Licenses run on a three-year cycle (current period ends June 30, 2029) with a full-term fee of $180, prorated for mid-cycle issuance, and renewal requires eight hours of board-approved continuing education per term.
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.
