Wyoming to South Dakota: master plumber license reciprocity

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.
