How to Become a Plumber in Wyoming

Plumbers in Wyoming begin their training through an official apprenticeship. After about four years, they apply for a journeyman plumber’s exam and license. This license allows plumbers to work independently while also being hired under licensed contractors. Journeyman plumbers can go on to become master plumbers and plumbing contractors if desired.

In Wyoming, licensure happens at the municipal level. This means each city will have unique rules and procedures to apply for your license. Let’s look at the licensing practices in the three largest WY cities: Cheyenne, Jackson, and Casper.

Do You Need a Plumbing License in Wyoming?

According to state law, no person can work as a residential, journeyman, or master plumber without the appropriate license or permit in Wyoming. There are a few exceptions, found on page 8 of the official Act.
