Wyoming plumber license requirements

This guide summarizes what Wyoming requires to work as a plumber, with a link to the state's own source for every requirement. Rules change; check the linked source before you apply.

Contractor license

No Wyoming statute creates a state plumbing contractor license. Where a county, city or town requires a contractor license, it issues its own, and requirements, bonds and fees vary. (source)

Licensed in another state

There is no state plumbing license to transfer, and W.S. 16-6-1101 does not cover licenses from other states. Under it, a Wyoming county, city or town that licenses contractors must recognize a contractor license of a similar type or class issued by another Wyoming county, city or town if the license is active, the contractor is in good standing, and the contractor shows proof of passing the International Code Council contractor, plumbing or mechanical exam, another appropriate exam, or an equivalent. The accepting jurisdiction may still require proof of financial assurance, and testing or fees for work the original license does not cover. The law applies to contractors; it does not clearly cover individual journeyman or apprentice cards. (source)
