Pennsylvania to Iowa: master plumber license reciprocity
Pennsylvania does not issue a statewide master 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 master plumber (all states except South Dakota): direct admission to the Iowa master exam
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
Iowa has no master plumber reciprocity with any state other than South Dakota. An applicant who holds a master plumbing license in another state or local jurisdiction is eligible to sit for the Iowa master plumbing exam without first holding an Iowa journeyperson license (DIAL master page; 481 IAC 429.6). The applicant files the $35 Exam Approval Application, waits up to two weeks for approval, schedules the exam with Kirkwood Community College ($95 per attempt), passes with 75%, and then files the post-examination licensure application with a prorated three-year license fee ($240 for a full term). An applicant who has established Iowa residency may instead apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4, but the board still requires proof of passing the applicable Iowa exam and can issue only a temporary license until then, so the practical path is the same. A master who intends to contract independently, or a firm employing the master, must also obtain the PMSB Contractor license and contractor registration ($400 for a full term, 30% discount on license fees when bought with the master license in one transaction) with $500,000 public liability insurance and a $5,000 surety bond; out-of-state contractors also file a $25,000 bond under Iowa Code chapter 91C.
Kirkwood exam fee quoted from DIAL's master page ($95); the journey page lists $99. Timeline reflects up to two weeks for exam approval plus up to six weeks for application review, excluding exam scheduling.

How Iowa licenses master plumbers
Iowa master plumber · “Master Plumber”
Statewide license
Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)
Iowa's highest person-held plumbing credential is the statewide Master Plumber license issued by the Plumbing and Mechanical Systems Board (DIAL); a master plans and superintends plumbing work, may perform all journeyperson duties, and serves as master of record for a licensed contractor (one contractor per discipline at a time without board approval). A new applicant must be 18, disclose criminal convictions, and pass the Iowa master plumbing exam; to sit for it the applicant must hold either a master plumbing license in another jurisdiction or a journeyperson license with two years of journey-level experience. The exam is approved by the board ($35 application) and administered by Kirkwood Community College ($95 per attempt as listed on the master page, 75% to pass). Iowa's only reciprocity agreement is with South Dakota for plumbers licensed by written exam; masters from all other states are admitted directly to the Iowa master exam on the strength of their license. The separate Contractor license ($250 plus $150 registration per three-year term, with $500,000 liability insurance and a $5,000 bond) is required to contract for plumbing work as a business. Licenses run three years (current period ends June 30, 2029) with a full-term fee of $240 and eight hours of continuing education per term.
Why Pennsylvania has nothing to transfer

Licensed by cities and counties
Pennsylvania issues no statewide master plumber or plumbing-contractor licence; none of the Department of State's 29 boards covers the trade, so the master-level credential exists only in cities that have chosen to license it. Allentown posts a 2026 Master Plumber Exam Application and requires a separate business licence to contract. Harrisburg posts a plumbing licence application whose master-versus-journeyman split was not verified. Pittsburgh's plumbing trade-licence page 404'd. There is no state-level recognition of an out-of-state master plumber licence and no municipal programme verified here that waives the plumbing trade exam. An arriving master should expect to apply city by city, document local experience thresholds, and sit each city's exam (ICC or city-written) unless that city later publishes an exam-waiver rule.
How local licensing works in Pennsylvania
How local licensing works. With no state plumbing board, each Pennsylvania city that licenses master plumbers does so under its own ordinance. The journeyman card, where it exists, does not authorise pulling permits or running a shop; the master (or master-contractor) licence does. A master licence is valid only in the issuing city. The journeyman page states that a journeyman works 'under a licensed master plumber' and may not operate a business, which implies the master licence is the contracting credential. Other PLI trade licences are issued to individuals, expire 365 days from issue, and (for electrical and mechanical) accept ICC master exams for any code year plus a stated experience total; whether plumbing follows that pattern is unverified. 2025 plumbing licence fee unknown.
Allentown. 2026 Master Plumber Exam Application is posted under Professional Trades Licensing. Contracting requires the trades licence and a city business licence. Reciprocity not mentioned on the landing page. Electrical Option B on that same form (eight years in lieu of exam) must not be assumed to apply to plumbing.
Inbound master. No Pennsylvania state licence and no verified exam-waiver reciprocity. Plan on a new application in each city where permits will be pulled. Philadelphia is the most fully documented shop: obtain the Master Plumber's License after (typically) holding or qualifying beyond the journeyman ICC path; confirm current master fees and exam on the master service page before applying. Allentown requires its master plumber exam application plus a business licence. Scranton uses the 2021 master contractor packet. Statewide reciprocity: none.
