Wyoming to Maryland: master plumber license reciprocity
Wyoming does not issue a statewide master 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 master 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.
An out-of-state master plumber whose origin is not the District of Columbia, Delaware, WSSC, or Baltimore County must pass the PSI Master Plumber/Gas Fitter examination before applying. The License Requirements page sets eligibility at two years as a journey plumber plus 3,750 hours of work as a journey plumber under a master. Upload proof of hours, backflow certification and a driver's license with the PSI application, sit at a Maryland PSI center, then apply for the original Master Plumber/Gas Fitter license and pay $87.50 (July 1, 2025). Masters must file a certificate of insurance: general liability of at least $300,000 and property damage of at least $100,000 ($400,000 per occurrence), Board as certificate holder, no umbrella. Reciprocal licenses for DC and Delaware (master only) are authored as agreements; WSSC and Baltimore County are municipal origins.
Occ. & Prof. qualification sections after §12-101. WSSC and Baltimore County are not origin state codes. Do not invent additional reciprocity partners.

How Maryland licenses master plumbers
Maryland master plumber · “Master Plumber/Gas Fitter”
State license plus local requirements
Issued by Maryland State Board of Plumbing (Department of Labor)
Maryland issues a statewide Master Plumber/Gas Fitter license through the State Board of Plumbing. By statute a master plumber is licensed to provide plumbing services and natural gas services. Qualification on the Board's License Requirements page is two years as a journey plumber plus 3,750 hours of work as a journey plumber under a master, then the PSI master exam. The original Master Plumber/Gas Fitter license fee is $87.50 (updated July 1, 2025; renewal is also $87.50). Masters must carry general liability of at least $300,000 and property damage of at least $100,000 ($400,000 per occurrence), with the Board named as certificate holder; umbrella policies are not accepted. Reciprocal Master Plumber/Gas Fitter licenses are issued to holders licensed by the District of Columbia, Delaware (master only), WSSC, or Baltimore County (WSSC and Baltimore County applicants must hold both plumbing and gas licenses obtained by examination).
How local licensing works in Maryland
Same territorial split as the journeyman level: the State Board license is not the license for Baltimore County or for WSSC territory in Montgomery and Prince George's Counties. Those jurisdictions license plumbers separately and enforce their own plumbing codes. A master who will contract in WSSC territory needs the WSSC plumber license; work only in Baltimore County needs the county license. Propane-gas-fitter certificates from the State Board are valid in the entire state. The reciprocal-license page states the Board may issue a State 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 master plumber
Licensed by cities and counties
Wyoming issues no master plumber or plumbing contractor license; the State Fire Marshal's electrical program is the only statewide trade licensing and it has no plumbing component. The master credential exists only in city ordinances: Cheyenne's Master (8,000 apprentice hours plus 6,000 journeyman hours and an ICC/NICET/NASCLA exam), Casper's Master Plumber (apprenticeship or four years plus five years as a journeyman or master, ICC G27-N), Laramie's master plumbing certificate of qualification (three years beyond journeyman, city exam), Gillette's Master Plumber (five years plus the ICC exam), Sheridan's Master Plumber (2018 ICC G27 with Gas) and Jackson's Master Certificate of Qualification (ICC G-series National Standard exam plus time in service). In every one of these cities a plumbing contractor must be or employ a master of record, and the contractor license is a separate business license with fees from $150 to $300 plus insurance or bond. No city accepts an out-of-state master license: Casper, Gillette and Jackson reciprocate only with other Wyoming jurisdictions, Sheridan refuses all outside licenses, Cheyenne's Board has undefined discretion, and Laramie may waive its exam for an equivalent certificate from any governmental agency. Rock Springs registers contractors for $125 with proof of insurance and tests nobody.
How local licensing works in Wyoming
How local licensing works. There is no state plumbing board; each city's ordinance defines its own master-level license and the plumbing contractor license it qualifies. The reciprocity statute the cities cite reaches only other Wyoming jurisdictions, and no city publishes a route that honours another state's master plumber or plumbing contractor license.
Cheyenne. A Master level craft employee license (12.1.8) requires 4 years/8,000 hours documented as an apprentice (or certified equivalent training) plus 3 years/6,000 hours documented as a journeyman and passing results on a current ICC, NICET or NASCLA exam from the Board's list. Fees are $50 application plus $50 initial and $25 renewal. A Plumbing (C1) contractor - covering plumbing and pipe-fitting systems other than fire sprinklers - may be licensed only if it always employs a full-time master or qualified supervisor of that class, who may represent only one contractor (13.0); the C1 tested contractor license costs $50 application plus $200 initial and $75 renewal. Reciprocity is at the Board's discretion (3.3.2/3.5.1) with no published partner list and a statute limiting it to Wyoming jurisdictions.
Casper. Master Plumber ($75 new, $37.50 renewal) requires a federally recognized plumbing apprenticeship or four years in a Casper-licensed plumbing shop plus five years as a journeyman or master plumber in a Casper-licensed shop, and proof of passing ICC G27-N or equivalent. A Plumbing Contractor license ($300/$150) covers any plumbing work including steam and water boilers, must be backed by a full-time licensed master plumber, and requires $250,000/$500,000/$250,000 liability insurance. Reciprocal Master/Journeyman licenses ($50/$25) are limited to holders of a current license from another Wyoming jurisdiction with comparable testing.
Laramie. A master plumbing certificate of qualification requires three years as a journeyman (Table 15.24.020-1) and the building official's examination ($5 per attempt), or is issued without exam on presentation of a certificate from another governmental agency whose exam the board of examiners finds at least equal. All plumbing contractor work must be performed by or under the supervision of a master plumbing certificate holder, who must be available to the building official within 24 hours. The Plumbing Contractor license costs $300 new and $35 renewal and requires a business location and telephone, a $500,000 combined single limit insurance certificate naming the City and a Wyoming Workers' Compensation certificate of good standing; licenses and certificates run January 1 - December 31.
Gillette. Master Plumber ($50 new, $50 renewal) requires five years of approved experience and passing ICC examination results. A Class D Plumbing Contractor ($150/$50) works under the 2024 IPC, may not do gas pipefitting on its plumbing license, and must designate a Master of Record - a full-time employee or owner licensed as a Master Plumber, able to reach any job site within 48 hours and replaced within 60 days if they leave. Reciprocity (5-III-1(d)) is limited to active, good-standing licenses from other Wyoming local governments, with testing waived on proof of the ICC plumbing or contractor exam and no fee charged.
Sheridan. Master Plumber ($50 new, $50 annual) acts as Master of Record for a plumbing company, must show they meet the Plumbing Contractor requirements (2018 ICC G27 exam, four-year journeyman plumber verification on Form JP, two-year project verification on Form A) and pass the 2018 ICC G27 Master Plumber with Gas exam. The Plumbing Contractor license ($200 new, $200 annual) also needs a $1,000,000 liability insurance certificate and a $10,000 license and permit bond, and every plumbing business must hold both a contractor license and a Master of Record. The City does not accept licenses from other cities, towns, counties or states.
Jackson. The Master Certificate of Qualification card is the prerequisite for a Plumbing Contractor license and is the only individual card the Town still issues. It is obtained by passing the ICC National Standard trades exam through Pearson VUE (only G-series tests based on the 2018 I-Codes are accepted) and meeting the time-in-service requirement in JMC 15.36.050, or by reciprocity for someone 'currently licensed and in good standing in a Wyoming jurisdiction that meets our licensing requirements'. Applications go through the SmartGov portal with a 30-day processing window; the contractor license then requires the bond and insurance in JMC 15.36.035 and renews every December 31, while the Master COQ card renews triennially with six hours of ICC-accredited continuing education. Licensing covers only work inside Town limits.
Rock Springs. Contractors register with the Building Inspection Office ($125 fee and a certificate of insurance naming the City) before working; no master license or exam exists.
