Kansas to Iowa: master plumber license reciprocity

No credit· Start overVerified September 16, 2026· 6 sources

Kansas does not issue a statewide master plumber license, so there is nothing to transfer. Here is Iowa'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.

Out-of-state master plumber (all states except South Dakota): direct admission to the Iowa master exam

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

Iowa has no master plumber reciprocity with any state other than South Dakota. An applicant who holds a master plumbing license in another state or local jurisdiction is eligible to sit for the Iowa master plumbing exam without first holding an Iowa journeyperson license (DIAL master page; 481 IAC 429.6). The applicant files the $35 Exam Approval Application, waits up to two weeks for approval, schedules the exam with Kirkwood Community College ($95 per attempt), passes with 75%, and then files the post-examination licensure application with a prorated three-year license fee ($240 for a full term). An applicant who has established Iowa residency may instead apply for licensure by verification under Iowa Code 272C.12 and 481 IAC 430.4, but the board still requires proof of passing the applicable Iowa exam and can issue only a temporary license until then, so the practical path is the same. A master who intends to contract independently, or a firm employing the master, must also obtain the PMSB Contractor license and contractor registration ($400 for a full term, 30% discount on license fees when bought with the master license in one transaction) with $500,000 public liability insurance and a $5,000 surety bond; out-of-state contractors also file a $25,000 bond under Iowa Code chapter 91C.

Kirkwood exam fee quoted from DIAL's master page ($95); the journey page lists $99. Timeline reflects up to two weeks for exam approval plus up to six weeks for application review, excluding exam scheduling.

Statewide license

Verified September 16, 2026· 4 sources

Issued by Iowa Plumbing and Mechanical Systems Board, Department of Inspections, Appeals, and Licensing (DIAL)

Iowa's highest person-held plumbing credential is the statewide Master Plumber license issued by the Plumbing and Mechanical Systems Board (DIAL); a master plans and superintends plumbing work, may perform all journeyperson duties, and serves as master of record for a licensed contractor (one contractor per discipline at a time without board approval). A new applicant must be 18, disclose criminal convictions, and pass the Iowa master plumbing exam; to sit for it the applicant must hold either a master plumbing license in another jurisdiction or a journeyperson license with two years of journey-level experience. The exam is approved by the board ($35 application) and administered by Kirkwood Community College ($95 per attempt as listed on the master page, 75% to pass). Iowa's only reciprocity agreement is with South Dakota for plumbers licensed by written exam; masters from all other states are admitted directly to the Iowa master exam on the strength of their license. The separate Contractor license ($250 plus $150 registration per three-year term, with $500,000 liability insurance and a $5,000 bond) is required to contract for plumbing work as a business. Licenses run three years (current period ends June 30, 2029) with a full-term fee of $240 and eight hours of continuing education per term.

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.
