Wyoming Plumber License Requirements (2026)

Wyoming does not publish a statewide plumber-license program. Plumbing credentials and permits are instead handled by the local authority with jurisdiction over the project. Requirements can therefore differ by city or county. Cheyenne is a clear example: it issues Class C-1 Plumbing Master & Contractor, Journeyman, and Apprentice credentials. Confirm the exact local credential, permit, code edition, insurance, and examination requirements with the authority where the work will occur before bidding or pulling a permit.

Who Issues the Wyoming Plumber License?

The Wyoming plumber license is issued under the rules described below. Wyoming does not publish a statewide plumber-licensing program. Local ordinances, permit rules, and building departments govern the work within their jurisdictions. A city or county with building-code jurisdiction may require local plumbing credentials and permits. The City of Cheyenne, for example, issues Class C-1 plumbing credentials; this is not a Wyoming state credential.

How to Get a Wyoming Plumber License, Step by Step

Identify the authority with jurisdiction. Confirm whether the project is inside a city, town, county, or another building-code jurisdiction before accepting the work.
Request the local plumbing and permit requirements. Ask the building department which contractor or individual credential, permit, code edition, plan review, and inspections apply to the project.
Meet the local credential requirements. Where required, apply for the local plumbing credential and satisfy the authority’s current qualified-supervisor, examination, or documentation rules.
Set up the business as applicable. Register an entity with the Wyoming Secretary of State if you choose an entity structure, and meet any applicable local business-registration requirement.
Pull permits and schedule inspections. Obtain the required local plumbing permit before starting regulated work and follow the jurisdiction’s inspection process.
Address right-of-way work separately. For example, Casper requires a street-cut permit for work in a street or alley and separately requires a plumbing permit for water or sewer work.

Application Checklist

Have each of these ready before you file with the Local authority:

Project address and jurisdiction confirmed
Current local plumbing credential requirements obtained
Local business-registration requirements checked
Required local contractor or individual credential obtained
Plumbing permit application submitted where required
Right-of-way permit, bond, and insurance addressed where applicable

Plumber Pay and Employment in Wyoming

The U.S. Bureau of Labor Statistics estimates that 1,140 plumbers, pipefitters, and steamfitters work in Wyoming, earning a median of $62,410 a year ($30.01 an hour). That is 2% below the national median of $63,800, ranking 31st of 51 jurisdictions BLS published. The lowest-paid 10% earn under $43,770 and the top 10% earn over $80,030. The trade is more concentrated in Wyoming's workforce than nationally (location quotient 1.35), so competition for jobs and for experienced hires tends to be higher.
