New York to Indiana: master plumber license reciprocity
New York does not issue a statewide master plumber license, so there is nothing to transfer. Here is Indiana'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.
Commission review of out-of-state master/contractor credentials (IC 25-28.5-1-19; no named partner states)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
An out-of-state master plumber or plumbing contractor applies to the Indiana Plumbing Commission for a Plumbing Contractor license through MyLicense One. Indiana names no reciprocal partner states, and the Commission's FAQ states that reciprocity is not available for contractor plumbers: the application goes before the Commission, and an approved applicant must pass the Indiana Plumbing Contractor exam given by Prov. IC 25-28.5-1-19 allows a license without examination where the origin state's requirements were substantially equal and that state grants Indiana licensees the same privilege, but the Commission's published process routes out-of-state licensees to the exam. You document your out-of-state license and four years of experience in the plumbing trade with an employer affidavit. The application fee is $50 and the initial license fee is $100 if issued in an even-numbered year or $50 in an odd-numbered year; a corporation must also hold its own corporate license naming you.
Indiana's statute provides for licensing without examination for holders from states with a reciprocity agreement or substantially equal requirements (IC 25-28.5-1-12(e) and -19), but the Commission names no such states and its FAQ says reciprocity is not available. Under IC 25-28.5-1-12(d), a license from a state without a reciprocity agreement makes the holder eligible to take the Indiana exam. The 90-question contractor exam includes 14 questions on Indiana business; there is no separate law exam. Indiana does not require a prior Indiana journeyman license for the contractor license. Nonresident licensees must also appoint the Commission's secretary as agent for service of process (IC 25-28.5-1-20).

How Indiana licenses master plumbers
Indiana master plumber · “Plumbing Contractor”
Statewide license
Issued by Indiana Plumbing Commission (Indiana Professional Licensing Agency)
Indiana has no 'master plumber' license. The top individual credential is the Plumbing Contractor license issued by the Indiana Plumbing Commission (PLA) under IC 25-28.5-1, which is held by a person who has qualified by experience and passed the Indiana plumbing contractor examination administered by PROV; this file maps it to the master level because it is the credential that authorizes a plumber to contract for and supervise plumbing work. The license is held by the individual: every member of a firm or partnership who contracts for plumbing work must hold one personally, and a corporation doing plumbing contracting must hold its own corporate license naming at least one officer or employee who is a licensed Plumbing Contractor (IC 25-28.5-1-13). The Commission also issues a Temporary Plumbing Contractor license when a contractor running a business dies or becomes unable to operate it (IC 25-28.5-1-18.5). Applications and renewals are processed in MyLicense One, and initial license issuance fees depend on whether the license is issued in an odd or even year. The reciprocity section of the statute (IC 25-28.5-1-19) applies to out-of-state master or contractor licensees in the same way as to journeymen.
Why New York has nothing to transfer
New York master plumber · “Master Plumber (municipal)”
Licensed by cities and counties
Issued by New York cities and counties (no statewide plumber license)
New York does not issue a statewide master plumber license. The Department of State Division of Licensing Services' 35 occupations do not include plumber. The person-held contracting credential is municipal. Westchester County requires a Master Plumber trade license to contract in the county (exam application $50, license and renewal $600; Restricted Master renewal $50 per municipality up to $600); Yonkers sits inside that county. Rochester lists Plumbing Licensing on its Licensed Trades portal without publishing fees.
How local licensing works in New York
How local licensing works. Master plumber licensing is entirely local. A Master Plumber license from one New York city or county does not authorize work in another, and New York State has no endorsement or reciprocity program for plumbers. There is no defaultPath and no agreements array at this level.
New York City. 'Master Plumbers are licensed to perform plumbing work in New York City.' Fees on the DOB master-plumbers page: license $200.00, renewal $150.00, late $50.00 (1–30 days) or $100.00 (31 days or more), seal $50.00 new / $75.00 renewal, term 3 years. Written exam application LIC41 $585; practical exam application LIC42 $530. A separate Master Fire Suppression Piping Contractor license uses the same fee/term schedule but does not cover plumbing work as defined in NYC Admin. Code §28-401.3. How-to: Obtain a Master Plumber License; renew a license; DPL-1 form; business-address verification. All new applications online via DOB NOW since 7 September 2021. Nothing on the landing page describes reciprocity.
Westchester County (including Yonkers). County law: plumbers must hold a Westchester trade license; first step is the licensing examination. Master Plumber exam application $50.00; Master Plumber license $600.00; Master Plumber renewal $600.00. Restricted Master Plumber renewal $50.00 per municipality, $600.00 maximum. Certificate of Competency (shelving) $50.00 per year. Late Master / Restricted Master renewals: $50 (1 Nov–31 Dec), $100 (1 Jan–30 Apr), $200 (1 May–31 Dec); after 31 December appearance before the Licensing Board. Exam/re-exam paid to the testing company (amount unpublished). The plumbing fee table has no 'reciprocal plumber' line (unlike electrical's 'Master and Reciprocal Electrician' on the same page). Yonkers work requires this county Master (or Restricted Master) plumber license.
Rochester. Plumbing Licensing is a listed Licensed Trade with online apply/pay/renew. For NYC, budget the $585 written and $530 practical exams plus $200 license / $50 seal and apply in DOB NOW; confirm experience and insurance on the obtain checklist before sitting.
