Kansas to Ohio: master plumber license reciprocity
Kansas 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 Kansas has nothing to transfer
Kansas master plumber
Licensed by cities and counties
Kansas issues no statewide master plumber or plumbing contractor license; the master credential exists only in county and city programs operating under K.S.A. 12-1508 and 12-1509. State law requires a master certificate to rest on a journeyman certificate held at least two years or four years of field experience, plus a 75% score on an ICC, IAPMO or Prometric standard master plumber exam, and makes a certificate earned that way valid proof of competency in every Kansas jurisdiction that licenses plumbers without additional examination. Sedgwick County/Wichita (MABCD) issues master plumber certificates ($35) on ICC K9F/557 Master Plumber with Gas or the IAPMO master exam; Johnson County uses the same ICC 557/KGF exam to qualify the individual behind a Class DP Plumbing Contractor license ($100 application plus $225 per license type); Topeka licenses trade contractors through a designated master with six hours of annual continuing education. None of the jurisdictions reviewed has a reciprocity agreement with another state, and MABCD states it 'does not reciprocate with state testing', so an out-of-state master plumber license transfers nothing except a qualifying ICC, IAPMO or Prometric score the applicant may already hold and documented experience. Lawrence and Kansas City, Kansas also license master plumbers, but their pages could not be retrieved in this pass.
How local licensing works in Kansas
How local licensing works. There is no state plumbing board. K.S.A. 12-1508 designates the ICC, IAPMO and Prometric standard exams for 'plumbing contractors and master and journeyman plumbers', and K.S.A. 12-1509 lets a county or city issue a master certificate of competency only after verifying that the applicant has held a valid journeyman certificate for at least two years or has at least four years of field experience, and has scored 75% on the standard master exam. That certificate 'shall be valid proof of competency for licensure, without additional examination, in any county or city of the state which requires licensure of plumbers'; each jurisdiction issues its own certificate for a uniform fee and requires 12 hours of continuing education biennially or six annually, half in code. Contracting (pulling permits and running a plumbing business) is licensed separately by each jurisdiction and generally requires a master-level qualifying individual plus insurance. The act is silent on out-of-state licenses; AG Op. 1999-42 says cities may not add licensure requirements beyond the act.
Sedgwick County and Wichita (MABCD). Plumbing master certificate ($35, Form 19A): must hold a plumbing journeyman certificate plus two years of field experience as a journeyman, or have four years of field experience, and score 75% or better on ICC K9F Master Plumber with Gas, ICC 557 Master Plumber with Gas or the IAPMO master exam, documented by an official passing letter. Certificates are good for two years and renew for $35 with three trade-specific and three general CEUs each year. MABCD 'does not reciprocate with state testing'; approved testing bodies are Block, Experior, Prometric, ICC and IAPMO, and MABCD no longer sponsors its own exams. Plumbing contractors are licensed separately by MABCD Contractor Licensing. Out-of-state treatment: an out-of-state master license is not accepted in lieu of the exam; a qualifying ICC 557-series or IAPMO master score plus documented experience is.
Johnson County. Does not license individuals. The master-level credential is the qualifying individual (QI) of a Class DP Plumbing Contractor license, who must present a verifiable passing score on ICC Master Plumbing with Gas (557/KGF); the county 'may be able to recognize ICC National exams if it can be verified to have a 75% or higher score.' The company pays a $100 application fee plus $225 per license type ($325 for one DP license), renews annually for $225 ($75 late fee from Feb. 1), and files general liability insurance, workers' compensation or a notarized waiver, and a Kansas Certificate of Good Standing if applicable; new applications are filed in person or by mail. A trade contractor's designated master must complete six hours of continuing education a year (three in the trade); licenses renew by December 14, fees are not prorated, and applications include the ICC passing certification or approved alternative education plus insurance and workers' compensation certificates (or a notarized exemption affidavit). V art. The applicant should obtain an official ICC (557/K9F/KGF series) or IAPMO master plumber passing letter (retesting through Pearson VUE or IAPMO if the origin exam was a state-specific test), document two years as a journeyman or four years of field experience, and apply to the first Kansas jurisdiction where they will work; under K.S.A. 12-1509(b) that certificate then supports licensure in every other Kansas county or city without another exam. A contractor license, insurance and, in Johnson County, a company-level Class DP license are separate requirements.
