Wyoming to Oklahoma: journeyman plumber license reciprocity

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

Wyoming does not issue a statewide journeyman 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 plumbing journeyman without a reciprocity agreement (all states except Arkansas)

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

A journeyman from any state other than Arkansas has no reciprocity route, because CIB publishes only the Arkansas plumbing agreement and OAC 158:30-5-4 requires a written agreement for the specific license sought. Under OAC 158:30-9-1.4 a journeyman from a state without an agreement, or from a jurisdiction with only local licensing, may request exam equivalency; if the Board has previously approved that jurisdiction's exam as substantially similar, the Oklahoma journeyman exam is waived on a certified letter from the licensing jurisdiction showing a current license in good standing, the license category, an exam score of 70% or higher and no pending discipline. CIB does not publish which jurisdictions' exams have been approved, and no equivalency form exists on the Plumbing Forms page. Otherwise the applicant files the Application for Plumbing Examination with notarized experience affidavits and a copy of the out-of-state license, which 'may expedite processing of the requirements' (OAC 158:30-9-1(k)(3)); out-of-state experience lawfully obtained counts toward the three-year requirement. The applicant pays $75 and must pass the Oklahoma plumbing journeyman exam through PSI with 75%. Oklahoma has no separate law exam for journeymen.

Vendor sites claim Oklahoma plumbing reciprocity with Texas, Colorado and Louisiana; none of those states appears on any CIB plumbing page, on the Plumbing Forms page (which offers only an Arkansas reciprocity application) or in OAC 158:30, so they are treated as default-path states here. Colorado's Plumbing Board has no reciprocal agreements at all. Which jurisdictions' exams the Board has approved for equivalency could not be confirmed from an official page. The exam pass mark is 75% under OAC 158:30-9-1(d), but the equivalency letter only needs a home-state score of 70% or higher. The exam code edition was in transition per CIB's '2026 Building Code Updates and Examination Transition Period' notice.

How Oklahoma licenses journeyman plumbers

Oklahoma journeyman plumber · “Unlimited Plumbing Journeyman

Statewide license

Verified September 16, 2026· 6 sources

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

Oklahoma issues statewide plumbing journeyman licenses through the Construction Industries Board (CIB) under the Plumbing License Law of 1955 and OAC Title 158, Chapter 30, in Unlimited and Residential categories. An Unlimited Plumbing Journeyman applicant must be 18 and show three years of verifiable experience in the plumbing trade while employed by a licensed plumbing contractor (about 2,000 hours per year, so roughly 6,000 hours; Oklahoma hours count only while registered as an apprentice), or equivalent U.S. military experience, with a Committee-approved 1,000-hour program substituting for two years and a 500-hour program for one year. The applicant pays $75 ($25 application plus $50 initial license), and must score 75% on the Oklahoma plumbing journeyman exam administered by PSI ($92 per portion). CIB has one published plumbing reciprocity agreement, with Arkansas (effective October 21, 2024, journeyman only); other out-of-state journeymen may seek exam equivalency if the Board has approved their jurisdiction's exam, and a current out-of-state license otherwise expedites processing of the experience requirement. Journeymen must work under a licensed plumbing contractor, renew annually ($75) and complete six hours of continuing education every 36 months.

Why Wyoming has nothing to transfer

Wyoming journeyman plumber

Licensed by cities and counties

Verified September 16, 2026· 12 sources

Wyoming has no statewide plumber license at any level. The only state construction-trade licensing program is the State Fire Marshal's electrician program, which lists no plumbing or mechanical credential, so a journeyman plumber license exists only where a city ordinance creates one. Cheyenne, Casper, Laramie, Gillette and Sheridan each license journeyman plumbers (and apprentices) individually, all requiring four years or a completed apprenticeship plus an ICC National Standard plumbing exam (G28-N journeyman or G27-N master), while Jackson has stopped issuing journeyman cards altogether and Rock Springs only registers contractors. No city accepts another state's journeyman license: Casper, Gillette and Jackson reciprocate only with other Wyoming jurisdictions, Sheridan expressly refuses licenses from other cities or states, Cheyenne's Board keeps discretion but cites a state statute limiting reciprocity to Wyoming jurisdictions, and Laramie's building official may waive the exam for a certificate from any governmental agency whose exam is judged at least equal. An out-of-state journeyman should expect to document their hours, present or sit the ICC exam through Pearson VUE, and apply separately in each city where they will work.

How local licensing works in Wyoming

How local licensing works. Wyoming licenses electricians through the State Fire Marshal but has no plumbing board, so plumber licensing is entirely a matter of city ordinance and each city sets its own classes, hours, exam and fees. The reciprocity statute the cities cite reaches only licenses issued by other Wyoming jurisdictions; none of the cities below publishes a path that recognizes another state's plumber license.

Cheyenne. The Contractor Licensing Board licenses Plumbing (Class C1, tested) contractors and requires every employee on a plumbing job site to hold a master, journeyman or apprentice license. A journeyman (12.1.9) documents 4 years/8,000 hours as a licensed apprentice (or certified equivalent training) and passes a current ICC, NICET or NASCLA exam from the Board's list, paid to the testing agency; a Residential Plumbing Journeyman (12.1.11) needs 2 years/4,000 hours and may work only on IRC residential structures at a 1:1 apprentice ratio. Fees: $50 application plus $30 initial and $15 renewal (apprentice $25 + $25, $15 renewal); licenses expire annually. Up to three apprentices may work under one journeyman or master. Trade employees registered for the exam can get a one-time 30-day temporary work authorization (60 days maximum). Reciprocity (3.3.2): the Board 'may grant reciprocity with other State jurisdictions and agencies as the Board determines appropriate', notes that Wyoming's statute allows reciprocity for Wyoming jurisdictions only, evaluates even those case by case, and may accept a test exceeding its published exams from someone holding a current equivalent license elsewhere - no partner list is published.

Casper. The Community Development Department issues Journeyman Plumber licenses ($25 new, $15 renewal) to applicants with a federally recognized plumbing apprenticeship or the equivalent of four years in a Casper-licensed plumbing shop plus proof of passing ICC G27-N or G28-N (or equivalent); apprentice licenses ($3) are issued to the contractor in the apprentice's name. Reciprocal Plumbing Master/Journeyman licenses ($50/$25) exist only for holders of a current, good-standing license from another Wyoming jurisdiction with comparable testing.

Laramie. A journeyman plumbing certificate of qualification requires four years' employment with a licensed plumbing contractor (Table 15.24.020-1) and the building official's examination; the application fee is $5 per exam attempt, and a failed exam bars retesting for 30 days (six months after a second failure). In lieu of the exam, the building official may issue the certificate to anyone presenting a valid certificate from 'any other governmental agency giving an examination' that the board of examiners considers at least equal - the only Wyoming city whose rule is not limited to Wyoming jurisdictions. Journeymen work only under a certified master, each journeyman or master may supervise two apprentices, certificates expire December 31 (renew by January 31), and applications go through the Civic Access portal.

Gillette. Journeyman Plumber ($25 new, $25 renewal) requires four years of approved experience and passing ICC examination results (5-III-21/22); the ICC computer-based exam is taken through Pearson VUE. Apprentices ($5) qualify after 30 days with a Gillette-licensed plumbing contractor, and one master or journeyman supervises up to three apprentices. Reciprocity (5-III-1(d), effective July 1, 2024) is granted without fee only to active, good-standing licenses of a similar class from another Wyoming city, county or town, with testing waived on proof of the ICC plumbing exam.

Sheridan. Journeyman Plumber ($50 new, $50 annual renewal) requires four years of journeyman plumber experience (Form JP) or a completed approved four-year apprenticeship and the 2018 ICC G28 Journeyman Plumber with Gas exam; one licensed contractor or journeyman is required per three apprentices. The City's FAQ states it 'does not accept licensing from other cities, towns, counties, or states as a means to obtain licensing locally'. Applications go through the OpenGov portal.

Jackson. The Town no longer issues or requires Apprentice or Journeyman Certificate of Qualification cards; only Master COQ cards are issued. A journeyman-level plumber works in Jackson as an employee of a Town-licensed plumbing contractor whose Master of Record holds a Master COQ, and needs no individual Town card.

Rock Springs. The Building Inspection Office registers contractors ($125 fee plus a certificate of insurance) and licenses no individual plumbers; no exam or hours are required.
