Kansas to Oklahoma: master plumber license reciprocity

No credit· Start overVerified September 16, 2026· 7 sources

Kansas does not issue a statewide master plumber license, so there is nothing to transfer. Here is Oklahoma'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 or plumbing contractor (all states; no contractor reciprocity agreements)

Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.

No state has a written plumbing contractor reciprocity agreement with Oklahoma, so every out-of-state master plumber or plumbing contractor uses the same route. Under OAC 158:30-9-1.4 a contractor-level applicant from a state without an agreement (or with only local licensing) may request exam equivalency; if the Board has previously approved that jurisdiction's exam, the technical trade section of the Oklahoma contractor exam is waived on a certified letter showing current good standing, the license category, a 70%+ exam score and no pending discipline, but 'the applicant for the contractor exam will still be required to take and pass the Oklahoma business and law section'. CIB does not publish the approved jurisdictions. Otherwise the applicant files the Application for Plumbing Examination with notarized experience affidavits and a copy of the out-of-state license, documents four years of verifiable plumbing experience (out-of-state hours count if lawfully obtained; a current out-of-state license may expedite processing), pays $330, and must pass both portions of the contractor exam through PSI with 75% each, completing the second portion within three years of approval. To activate the license the contractor files a $5,000 bond and $50,000 general liability insurance with CIB, or the Affidavit for Plumbing waiver if employed by a single entity.

Even where a written contractor agreement exists, OAC 158:30-5-4(e) grants only a journeyman license by reciprocity and requires the Oklahoma Plumbing Contractor Business and Law portion before the contractor license issues; since CIB publishes no plumbing contractor agreement with any state, no contractor reciprocity rows are recorded. Vendor claims of Oklahoma plumbing reciprocity with Texas, Colorado or Louisiana could not be confirmed from any CIB page.

How Oklahoma licenses master plumbers

Oklahoma master plumber · “Plumbing Contractor (Unlimited)

Statewide license

Verified September 16, 2026· 6 sources

Issued by Oklahoma Construction Industries Board (CIB), Plumbing Division

Oklahoma has no 'master plumber' title; its highest person-held plumbing credential is the Plumbing Contractor license, which CIB describes as 'the highest ranking plumbing license' and issues to an individual who passes the two-part contractor exam (technical trade and Plumbing Business and Law, 75% on each part, PSI, $92 per portion). This site maps the Unlimited Plumbing Contractor license to the master level. An applicant needs the journeyman qualifications plus one additional year, so four years (about 8,000 hours) of verifiable plumbing experience, and pays $330 ($30 application plus $300 initial license). After passing, the license is inactive until the contractor files a $5,000 corporate surety bond (or $5,000 cash or certificate of deposit) and a $50,000 commercial general liability certificate with CIB; only a licensed contractor may contract for plumbing work, and the licensee may operate as an individual, firm, LLC or corporation. CIB's Arkansas agreement covers journeymen only, so no state has contractor reciprocity with Oklahoma; out-of-state masters and contractors use exam equivalency where available or sit the full exam. Licenses renew annually ($200) with six hours of continuing education every 36 months.

Why Kansas has nothing to transfer

Kansas master plumber

Licensed by cities and counties

Verified September 16, 2026· 6 sources

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.
