Wyoming to Maryland: journeyman plumber license reciprocity

No credit· Start overVerified September 16, 2026· 9 sources

Wyoming does not issue a statewide journeyman plumber license, so there is nothing to transfer. Here is Maryland'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 journey plumber by examination (PSI), unless a reciprocal license applies

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

For any origin that is not the District of Columbia, WSSC, or Baltimore County, Maryland does not waive the journey plumber exam. The License Requirements page sets eligibility at four years as an apprentice plumber plus 7,500 hours of apprentice work, a 32-hour backflow prevention certification, and the PSI journey exam. Upload proof of hours, backflow certification and a driver's license to PSI's Client Portal, then register at test-takers.psiexams.com/mdplu (centers in Baltimore, College Park, Hagerstown, Lanham and Salisbury). After passing, apply for the original Journeyman Plumber/Gas Fitter license and pay the $43.50 fee (July 1, 2025 schedule). Reciprocal licenses for DC, WSSC and Baltimore County are authored as agreements (WSSC/Baltimore County are municipal origins, not state codes). There is no published separate Maryland law or business exam on the pages reviewed.

Occ. & Prof. qualification and waiver sections after §12-101. WSSC and Baltimore County are Maryland municipal issuers, not origin state codes; they are recorded via acceptsMunicipalOriginLicenses and municipalNotes rather than agreements.origin. Insurance on plinsure.shtml is written for masters. Do not treat this default path as Reciprocity.

Issued by Maryland State Board of Plumbing (Department of Labor)

Maryland issues a statewide Journeyman Plumber/Gas Fitter license (statutory name: journey plumber) through the State Board of Plumbing in the Department of Labor. A journey plumber provides plumbing services under the direction and control of a master plumber or limited master plumber. Qualification on the Board's License Requirements page is four years as an apprentice plumber plus 7,500 hours of apprentice work, a 32-hour backflow prevention certification, and the PSI journey exam. State plumber licenses are required throughout Maryland except Baltimore County and the Washington Suburban Sanitary Commission (WSSC) service area in Montgomery and Prince George's Counties, which issue their own plumber licenses. The original license fee is $43.50 (updated July 1, 2025). The Board issues reciprocal Journey Plumber/Gas Fitter licenses to holders licensed by the District of Columbia, WSSC, or Baltimore County (WSSC and Baltimore County applicants must hold both plumbing and gas licenses obtained by examination). Apprentice plumber licenses may be renewed for only two consecutive cycles before the journey exam is required (Bus. Occ. & Prof. §12-308.1).

How local licensing works in Maryland

The Board's home page states that State plumber and natural-gas-fitter licenses are required throughout Maryland except (1) Baltimore County and (2) areas served by WSSC in Prince George's and Montgomery Counties; those two jurisdictions issue their own licenses and have their own plumbing code. Propane-gas-fitter certificates from the State Board are valid statewide, including those counties. Inbound plumbers who will work only in Montgomery or Prince George's County should apply to WSSC, not (or not only) to the State Board; work only in Baltimore County goes through Baltimore County. Work in the remaining counties and Baltimore City uses the State Board license. The reciprocal-license page states the Board may issue a State journey or master plumber license to a person already licensed by WSSC or Baltimore County if that person holds both plumbing and gas licenses obtained by examination.

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.
