New York to Ohio: master plumber license reciprocity
New York does not issue a statewide master plumber license, so there is nothing to transfer. Here is Ohio'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 plumbing contractor or master plumber without a reciprocity agreement (examination route)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A plumbing contractor or master plumber licensed in a state without an OCILB reciprocity agreement must take the Ohio examination; neither R.C. 4740.06 nor OCILB's pages provide a case-by-case exam waiver outside a written reciprocity agreement (R.C. 4740.08). R.C. 4740.06(C) and OCILB's Out-of-State Examination Application let the out-of-state license stand in for the usual five years of Ohio tax and permit documentation: the applicant instead shows the substantially similar license has been active for at least five years (letter of good standing), at least five building authorizations issued under it, one tax return reflecting income under the license (plus a W-2 if not the owner), and that their employer is registered in Ohio as a foreign corporation or LLC with a designated agent. The board secretary must approve a complete out-of-state exam application within 30 days; the applicant then completes BCI and FBI background checks (approval valid one year) and passes both sections of the PSI exam (Plumbing trade and Business & Law). The license is issued on submission of the results, a $25 fee and a $500,000 certificate of liability insurance, and must be assigned to a contracting company; the specialty section must authorize the license within 90 days of the application once the applicant qualifies and passes.
Mechanism is ExperienceCredit rather than Endorsement because OCILB waives the trade exam only under a written reciprocity agreement with a named state; the out-of-state route only substitutes the origin license for Ohio experience documentation. The PSI examination fee, pass mark and question counts are published only in the PSI Candidate Information Bulletin sent to approved candidates and were not confirmed from an official page. Kentucky plumbing licensees are not on OCILB's plumbing reciprocity list (Kentucky is listed for Electrical, HVAC and Refrigeration only) and use this path.

How Ohio licenses master plumbers
Ohio master plumber · “Plumbing Contractor (OCILB state license)”
Statewide license
Issued by Ohio Construction Industry Licensing Board (OCILB), Ohio Department of Commerce
Ohio has no license called 'master plumber'; its top person-held plumbing credential is the statewide Plumbing Contractor license issued by the Ohio Construction Industry Licensing Board (OCILB) to an individual who qualified by examination (R.C. 4740.01(A)), who then assigns it to a contracting company. Other states' reciprocity forms pair this license with their master plumber licenses (West Virginia's form, for example, matches its Master Plumber to Ohio's Plumbing Contractor), so it is treated here as the master level. A new applicant must be 18, a citizen or legal alien, have five years as a tradesperson in the plumbing trade immediately before applying (or be an Ohio registered engineer with three years of construction business experience), pass BCI and FBI background checks, pass both sections of the PSI-administered examination (Plumbing trade and Business & Law), carry $500,000 of contractor liability insurance in one company name, and pay a $25 application fee and $25 license fee; licenses expire annually and renew with continuing education (online CE limited to 4 hours per one-year renewal). OCILB's published reciprocity list covers plumbing licenses from Arkansas, Mississippi, South Carolina, Tennessee and West Virginia, with the Ohio Business and Law exam still required for Mississippi, South Carolina and Tennessee licensees.
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 licence)
New York does not issue a statewide master plumber licence. 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 licence to contract in the county (exam application $50, licence 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 licence from one New York city or county does not authorise work in another, and New York State has no endorsement or reciprocity programme 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: licence $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 licence 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 licence; 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 licence; first step is the licensing examination. Master Plumber exam application $50.00; Master Plumber licence $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 licence.
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 licence / $50 seal and apply in DOB NOW; confirm experience and insurance on the obtain checklist before sitting. For Westchester, file the $50 exam application and $600 licence. For Rochester, Buffalo, Syracuse and Albany, contact the local board — published inbound rules were not verified here.
