Wyoming Plumber License Requirements (2026)
By Gabriel Giner, Editor · Source checked 2026-09-04
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.
Regulatory Body

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.

Step-by-Step Application Roadmap
- 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.
