No Wyoming statute licenses plumbers or plumbing contractors statewide. Plumbing licensing, where it exists, is local, and W.S. 16-6-1101 requires a Wyoming city, town, or county to recognize another Wyoming jurisdiction's active, good-standing license when the plumber shows a passing ICC plumbing exam or equivalent — without retesting. Plumbing permits and inspections come from the jurisdictions that have taken code enforcement authority from the State Fire Marshal (W.S. 35-9-121).
One narrow state license touches the trade: under W.S. 33-42-103(f) it is unlawful to construct, alter, or rehabilitate a water well or install pumping equipment in a water well without a license from the state board of examining water well drilling contractors and water well pump installation contractors, unless exempt. Plumbing contractors that employ workers must also carry Wyoming workers' compensation (construction is extrahazardous employment) and send a preliminary lien notice before taking any payment.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Wyoming has no statewide license for this trade, so contractor licensing is local. Cities, towns, and counties that license contractors set their own classes, exams, and bonds, but W.S. 16-6-1101 requires each of them to recognize an active, good-standing license issued by another Wyoming jurisdiction when the contractor shows a passing International Code Council (or equivalent) exam — with no retesting, though the accepting jurisdiction may require its own proof of financial assurance. Building codes are enforced by municipalities and counties that have taken delegated authority from the State Fire Marshal (W.S. 35-9-121), and any electrical work stays with state-licensed electrical contractors (W.S. 35-9-123).

Another Wyoming jurisdiction must recognize your local license without retesting if you show a passing ICC or equivalent exam (W.S. 16-6-1101(b)(ii)).

A contractor, subcontractor, or materialman who does not send the preliminary notice within the time required loses the right to assert a construction lien.
