Wyoming to Ohio: master plumber license reciprocity
Wyoming does not issue a statewide master plumber license, so there is nothing to transfer. Here is Ohio'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 contractor or master plumber without a reciprocity agreement (examination route)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A plumbing contractor or master plumber licensed in a state without an OCILB reciprocity agreement must take the Ohio examination; neither R.C. 4740.06 nor OCILB's pages provide a case-by-case exam waiver outside a written reciprocity agreement (R.C. 4740.08). R.C. 4740.06(C) and OCILB's Out-of-State Examination Application let the out-of-state license stand in for the usual five years of Ohio tax and permit documentation: the applicant instead shows the substantially similar license has been active for at least five years (letter of good standing), at least five building authorizations issued under it, one tax return reflecting income under the license (plus a W-2 if not the owner), and that their employer is registered in Ohio as a foreign corporation or LLC with a designated agent. The board secretary must approve a complete out-of-state exam application within 30 days; the applicant then completes BCI and FBI background checks (approval valid one year) and passes both sections of the PSI exam (Plumbing trade and Business & Law). The license is issued on submission of the results, a $25 fee and a $500,000 certificate of liability insurance, and must be assigned to a contracting company; the specialty section must authorize the license within 90 days of the application once the applicant qualifies and passes.
Mechanism is ExperienceCredit rather than Endorsement because OCILB waives the trade exam only under a written reciprocity agreement with a named state; the out-of-state route only substitutes the origin license for Ohio experience documentation. The PSI examination fee, pass mark and question counts are published only in the PSI Candidate Information Bulletin sent to approved candidates and were not confirmed from an official page. Kentucky plumbing licensees are not on OCILB's plumbing reciprocity list (Kentucky is listed for Electrical, HVAC and Refrigeration only) and use this path.

How Ohio licenses master plumbers
Ohio master plumber · “Plumbing Contractor (OCILB state license)”
Statewide license
Issued by Ohio Construction Industry Licensing Board (OCILB), Ohio Department of Commerce
Ohio has no license called 'master plumber'; its top person-held plumbing credential is the statewide Plumbing Contractor license issued by the Ohio Construction Industry Licensing Board (OCILB) to an individual who qualified by examination (R.C. 4740.01(A)), who then assigns it to a contracting company. Other states' reciprocity forms pair this license with their master plumber licenses (West Virginia's form, for example, matches its Master Plumber to Ohio's Plumbing Contractor), so it is treated here as the master level. A new applicant must be 18, a citizen or legal alien, have five years as a tradesperson in the plumbing trade immediately before applying (or be an Ohio registered engineer with three years of construction business experience), pass BCI and FBI background checks, pass both sections of the PSI-administered examination (Plumbing trade and Business & Law), carry $500,000 of contractor liability insurance in one company name, and pay a $25 application fee and $25 license fee; licenses expire annually and renew with continuing education (online CE limited to 4 hours per one-year renewal). OCILB's published reciprocity list covers plumbing licenses from Arkansas, Mississippi, South Carolina, Tennessee and West Virginia, with the Ohio Business and Law exam still required for Mississippi, South Carolina and Tennessee licensees.
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.
