Kansas to Illinois: 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 Illinois'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.

Licensure by examination for out-of-state plumbers (225 ILCS 320/17(b)); exam waiver under 17(a) only where a reciprocal arrangement exists

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

A plumber licensed or registered by another state or municipality applies to IDPH under Section 17 of the Plumbing License Law. Under 17(b), if the State Board of Plumbing Examiners finds the origin jurisdiction's licence requirements 'substantially equal to the requirements for an Illinois Plumber's license' but that jurisdiction has no reciprocal agreement with Illinois, the applicant 'may apply for and be issued an Illinois Plumber's license provided that the applicant successfully passes the Illinois plumber's examination and pays the required fees'; the out-of-state licence stands in for the four-year Illinois apprenticeship that Section 10 otherwise requires. Under 17(a), the exam is waived only if the applicant is at least 21, the Board finds the origin requirements were substantially equal at the date of the origin licence, and the origin state accords the same privilege to Illinois plumbers; IDPH publishes a reciprocity form only for City of Chicago licensees and names no partner state, so this file treats every state origin as the 17(b) exam route. The Illinois examination is a single IDPH-administered test of planning and design, manual skills and the Illinois Plumbing Code, offered at least every three months, with the application due 30 days before the exam date. An origin licence whose requirements are not substantially equal gives no advantage; the applicant must complete the Illinois apprentice route. Once licensed, the plumber renews every April 30 with four hours of CE and must register a Plumbing Contractor (insurance and $20,000 bond) to contract for work.

Adm. The task brief cited 225 ILCS 320 Section 13 for out-of-state licensure; the operative section is 17 (Section 13 covers re-examination).

How Illinois licenses master plumbers

State license plus local requirements

Verified September 16, 2026· 5 sources

Issued by Illinois Department of Public Health (IDPH), Plumbing Program, with the Illinois State Board of Plumbing Examiners; City of Chicago Department of Buildings under 225 ILCS 320/16

Illinois' only full plumbing credential is the Plumber licence issued by the Department of Public Health; it is the state's equivalent of a master licence because a licensed plumber may plan, design, install and inspect all plumbing, sponsor up to two apprentices, and serve as the licence-holding member or officer of a registered Plumbing Contractor. The standard route is four years (48 to 72 months) as an Illinois licensed apprentice plumber or completion of an approved college/trade-school plumbing course, two years of high school or equivalent, an application filed at least 30 days before an exam date, and passing the IDPH-administered examination (held at least quarterly), which covers planning and design, manual skills, and the Illinois Plumbing Code (77 Ill. Adm. Code 890). Licences expire every April 30 and renew annually with four hours of continuing education. The City of Chicago runs a parallel plumber licence under Section 16 of the Act, and by statute a plumber licensed by either IDPH or Chicago may work anywhere in Illinois, so the two licences are alternatives rather than stacked requirements. Out-of-state plumbers are handled under Section 17: without examination only where the origin state's requirements were substantially equal at the time of licensure and that state reciprocates with Illinois (no state partner is named by IDPH), otherwise by passing the Illinois plumber's examination.

How local licensing works in Illinois

Chicago. Section 16 of the Plumbing License Law lets a municipality of 500,000 or more (only Chicago qualifies) adopt an ordinance 'substantially the same' as the Act with equivalent education or experience requirements and run its own board of plumbing examiners; within Chicago the state Act then does not apply except as the Act provides. The City of Chicago Department of Buildings issues that plumber licence. Section 16(2) provides that 'any person licensed as a plumber pursuant to such ordinance, or licensed by the Department under this Act, may engage in plumbing anywhere in this State', so an IDPH licence is valid in Chicago and a Chicago licence is valid in the rest of Illinois; Section 13.1(9) also accepts a Chicago plumber licence for state Plumbing Contractor registration. IDPH separately publishes a 'Plumber's License: Application for Reciprocity for the City of Chicago Licensees' for Chicago plumbers who want the state card as well. Local governments may adopt a plumbing code at least as stringent as the State code, require permits, and employ licensed plumbers as inspectors (Sections 18, 36, 37), but they cannot require a separate individual plumber licence.

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.

Common questions

Do I have to take the Illinois master plumber exam if I'm licensed in Kansas?
Yes. Illinois requires the trade exam on this path.
Do my Kansas work hours count in Illinois?
Yes. Documented out-of-state experience counts toward Illinois's eligibility requirements.
Does it work the other way, from Illinois to Kansas?
Not necessarily. Reciprocity is directed. Going from Illinois to Kansas, the mechanism is not applicable.
