New York to Kentucky: journeyman plumber license reciprocity
New York 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 New York has nothing to transfer

Licensed by cities and counties
Issued by New York cities and counties (no statewide plumber licence)
New York has no statewide plumber licence at any level: the Department of State's Division of Licensing Services regulates 35 occupations and none of them is plumber, plumbing contractor, journeyman plumber or master plumber. Journeyman-level plumbing credentials therefore exist only where a city or county ordinance creates them, and they are not interchangeable. New York City's Department of Buildings issues a Journeyman Plumber / Fire Suppression Piping Installer registration (employees work under a licensed Master Plumber; the registration is not an independent contracting licence). Westchester County issues a Journey-Level plumber licence (exam application $25, licence and renewal $75) that is required to work as a plumber anywhere in the county, including Yonkers. Rochester publishes a Plumbing Licensing programme on its Licensed Trades page but does not list class names or fees on that page. An out-of-state journeyman plumber licence has no state-level recognition in New York; the arriving worker must satisfy the city or county where the work will be done, and in New York City that typically means working under a licensed Master Plumber while holding (or obtaining) the city journeyman registration.
How local licensing works in New York
How local licensing works. No state agency licenses plumbers in New York. Each city or county that requires a licence runs its own examining board under its own ordinance, so titles, exams and fees differ, and a licence from one jurisdiction is not automatically valid in another. There is no defaultPath and no state-to-state agreement at this level.
New York City. DOB's licence-types list includes 'Plumbing and Fire Suppression (Master and Journeyman)'. The master-plumbers page links Obtain a Journeyman Plumber / Fire Suppression Piping Installer Registration (and a separate Gas Work Qualification). The registration is person-held and is the city's journeyman-level credential; independent plumbing contracting in the five boroughs requires the Master Plumber licence (see master level). New applications go through DOB NOW (since 7 September 2021). The master written (LIC41, $585) and practical (LIC42, $530) exam fees published on the master-plumbers page apply to the Master Plumber licence, not to the journeyman registration.
Westchester County (including Yonkers). 'Plumbers and Electricians must obtain a trade license from Westchester County in order to work in the county. The first step is to apply to take the licensing examination.' Journey-Level exam application $25.00; Journey-Level licence $75.00; Journey-Level renewal $75.00; vehicle decals $5.00 each. Exam and re-examination amounts are paid to the testing company and are not listed on the fee page. Yonkers does not appear to issue a separate city plumber licence; county law requires the Westchester trade licence to work in the county.
Rochester. The Licensed Trades page lists Plumbing Licensing alongside electrical and SE/RO and routes applications to the city's Infor portal (585-428-9339). Confirm the destination city or county before working; in NYC plan to work under a Master Plumber and obtain the city journeyman registration; in Westchester apply for the Journey-Level exam.
