Plumber Licensing in Wyoming

Wyoming Plumber License Verification

In Wyoming, plumber licensing is primarily regulated at the local municipal level, rather than by a single statewide board. This means that individuals seeking to work as plumbers in 2026 must consult the specific requirements of the city or county where they intend to practice. Common license types include Apprentice, Journeyman, and Master Plumber, each with distinct qualifications. Generally, becoming a journeyman plumber in Wyoming requires completing a four-year apprenticeship, typically involving 5,600 to 8,000 hours of supervised on-the-job training. Applicants must also pass a plumbing examination, often based on the International Code Council (ICC) National Exam, with a passing score of at least 75%. Master plumbers typically need additional years of documented experience as a journeyman, followed by passing a master plumber examination.

Insurance and Bonding Mandates

For plumbing contractors in Wyoming, specific insurance and bonding mandates are generally established by local municipalities. While the state does not issue statewide plumbing licenses, most local jurisdictions require plumbing businesses to obtain appropriate liability and workers' compensation insurance. Additionally, many cities and counties mandate a contractor license bond as part of their licensing requirements. The amount of this bond can vary significantly by municipality; for example, the Town of Jackson may require a $10,000 bond, while the City of Gillette might require $5,000. Nonresident prime contractors may also have state-level surety bond requirements to secure payment of use taxes with the Wyoming Department of Revenue.

Permitting and Local Regulations

Plumbing work in Wyoming, including new installations, alterations, repairs, and replacements of plumbing systems, necessitates obtaining permits from local authorities prior to commencing work. These local regulations often incorporate the International Plumbing Code (IPC) as their adopted standard for construction and safety. It is the responsibility of the plumber or the property owner to ensure that all necessary permits are acquired and that work adheres to the local municipal codes and standards. Failure to obtain required permits can result in fines and project delays. Beyond general plumbing permits, specific projects might require additional review or coordination with local building safety departments.
