Kansas to Colorado: journeyman plumber license reciprocity

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

Kansas does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Colorado'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 endorsement (all other states; no reciprocal agreements)

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

Every out-of-state journeyman applies under the same endorsement rule, because the Colorado Plumbing Board has no reciprocal agreements (the word does not appear in 3 CCR 720-1 or on the DPO plumbing pages). Under Rule 1.4(B)(1)(a) and the DPO Licensure Requirements, the applicant must hold an active journeyman-level license issued and regulated by a state (not a city or county) for at least six months, must have obtained it by passing a comparable state plumbing exam based on the current or previous edition of the plumbing code adopted by the Board (the 2021 IPC; DPO's Licensing Guide phrases this as 'the current or previous version of the International Plumbing Code'), and must have completed a state or federally approved apprenticeship or the four years (6,800 hours) of experience Colorado requires, documented on the Board's Affidavit of Experience forms signed by employers (self-verification is not accepted). The issuing state board completes DPO's Verification of State Licensure form. An applicant who satisfies these conditions is licensed without taking the Colorado exam; anyone who does not (for example a licence gained without an exam, on a non-IPC code, or held under six months) applies by examination, where out-of-state hours still count toward the 6,800-hour requirement.

Wording differences between official sources: the DPO Applications page says the comparable exam must be 'based on the currently adopted Colorado Code', while Rule 1.4(B)(1)(a)(2) and the Licensing Guide accept the current OR previous edition of the adopted plumbing code (IPC). The six-month holding period appears on the DPO Applications page but not in the rule text. Rule 1.4(A)(1) says candidates 'must pass the required examination(s) before submitting an application', whereas the Applications page describes DPO approving the application first and then issuing PSI scheduling instructions; exam-route applicants should confirm the current order of operations with DPO. The $120 application fee is quoted as 'currently' in the DPO Licensing Guide; the PSI exam fee is set in PSI's candidate handbook and was not published on the DPO pages reviewed. C.R.S.

How Colorado licenses journeyman plumbers

Statewide license

Verified September 16, 2026· 5 sources

Issued by Colorado State Plumbing Board (DORA Division of Professions and Occupations)

Colorado issues a statewide Journeyworker Plumber license (its name for the journeyman level) through the State Plumbing Board in DORA's Division of Professions and Occupations; the Board also licenses Residential Plumbers (two years / 3,400 hours) and Master Plumbers, registers apprentices, and registers Plumbing Contractors, which must hold or employ a licensed master plumber. By examination a journeyworker needs four years (6,800 hours) of documented practical experience verified on Affidavit of Experience forms by plumbing contractors or employers, a $120 application fee, and a passing score of 70% on the PSI-administered Colorado journeyworker exam (100 multiple-choice questions, 240 minutes) based on the 2021 IPC/IRC as adopted in 3 CCR 720-1. Out-of-state licensees who meet Board Rule 1.4(B)(1)(a) may instead be licensed by endorsement without the Colorado exam; the Board publishes no reciprocal agreements with any state. Licenses expire on the last day of February of odd-numbered years, and renewal requires eight hours of continuing education per licence year (waived until after the first renewal for new exam licensees).

Why Kansas has nothing to transfer

Kansas journeyman plumber

Licensed by cities and counties

Verified September 16, 2026· 6 sources

Kansas has no statewide journeyman plumber license and no state plumbing board. K.S.A. 12-1508 and 12-1509 only set a framework for the counties and cities that choose to license plumbers: they must use the ICC, IAPMO or Prometric standard exams, require a 75% score, verify two years of field experience (up to one year creditable from a 930-hour trade-school program), charge a uniform fee and require 12 hours of continuing education every two years, half of it code education. A journeyman certificate of competency earned that way is valid proof of competency in every other Kansas county or city that licenses plumbers without additional examination, but each jurisdiction still issues its own license and collects its own fee. Sedgwick County/Wichita (MABCD) and Topeka license journeyman plumbers individually; Johnson County licenses only plumbing contractors (Class DP) and issues no journeyman card. No Kansas jurisdiction found in this pass accepts another state's journeyman license in place of the exam (MABCD states it 'does not reciprocate with state testing'), so an out-of-state journeyman transfers only a qualifying ICC, IAPMO or Prometric score they may already hold, plus documented hours.

How local licensing works in Kansas

How local licensing works. Kansas has no state plumbing license, board or application. Under K.S.A. 12-1508 to 12-1509 a county or city that licenses plumbers must accept only the ICC, IAPMO or Prometric standard plumbing exams (and may ask no other questions), require a 75% passing score, verify two years of field experience under a licensed journeyman or master (one year of which may be a trade-school program of at least 930 hours), set one uniform exam and license fee for all applicants, and require 12 hours of continuing education biennially or six annually with half in code education. A journeyman certificate of competency issued on a standard exam 'shall be valid proof of competency for licensure, without additional examination, in any county or city of the state', and the receiving jurisdiction must issue its own certificate for its uniform fee (K.S.A. 12-1509(b)-(c)). The Attorney General has opined that a city may not use home-rule power to add licensing requirements beyond the act (AG Op. 1999-42). Medical gas piping additionally requires ASSE Series 6000 certification (K.S.A. 12-1509(g)). Nothing in the act addresses licenses from other states.

Sedgwick County and Wichita (MABCD). Requires every journeyman plumber working in Wichita or unincorporated Sedgwick County to hold an MABCD trade certificate. Plumbing journeyman: one year of field experience plus one year of plumbing trade school, or two years of field experience (documented on company letterhead with a description of the work), and a 75% or better score on ICC K9R Plumbing with Gas, ICC 560 Journeyman Plumber with Gas or the IAPMO journeyman exam; submit Form 19A with the official passing letter, transcripts and experience proof and pay $35. Certificates run two years and renew for $35 with three trade-specific and three general CEUs per year (12 per cycle), with penalty hours if expired. MABCD no longer sponsors exams; candidates test through Pearson VUE (ICC) or IAPMO. Out-of-state treatment: 'MABCD does not reciprocate with state testing, only those exams listed below are approved for Sedgwick County.' An out-of-state journeyman license is not accepted as a substitute; the applicant needs a passing ICC K9R/560 or IAPMO score (many states' ICC national journeyman plumber exams are the same 560 series, but MABCD requires the official letter naming the exam) and documented hours.

Johnson County (Olathe, Overland Park, Lenexa, Shawnee and the other cities in the county program). Johnson County Contractor Licensing issues contractor licenses only; there is no journeyman plumber license. Plumbing work is done by a company holding a Class DP Plumbing Contractor license ($100 application plus $225 per license type, $225 annual renewal, $75 late fee from Feb. 1) whose qualifying individual has passed the ICC Master Plumbing with Gas exam (557/KGF). A journeyman arriving from another state works as an employee of a licensed DP contractor without any personal county license. Applications include the ICC passing certification or approved alternative education, liability and workers' compensation certificates, and can take up to 10 days. V art. 17 'Electrical, Mechanical and Plumbing Trade Licensing'; the Unified Government's Building Inspection trade licensing and Prometric testing program). What ports is (1) a passing score on an ICC, IAPMO or Prometric standard journeyman plumber exam, documented by an official letter, and (2) verifiable field experience of at least two years. With those, the applicant obtains a certificate from the first Kansas jurisdiction they work in and can then be licensed in any other Kansas county or city without retesting under K.S.A. 12-1509(b), paying each jurisdiction's fee and meeting its CE.
