Table of Contents

Like most states, Texas requires people working in the plumbing industry to be licensed. Learn more about how to get a plumbing license and eventually begin work as a plumber in Texas.

Texas Plumbing License Requirements

Texas strictly forbids providing services without a license. Apprentices are allowed to work under the direction of licensed plumbers.

From there, various licenses are available. Rising through the ranks of the industry can take several years.

Apprentices aren’t required to have a high school diploma or GED, but they must obtain one of the two to ultimately become licensed plumbers.

Types of Plumbing Licenses in Texas

Four types of plumber licenses are available in the state of Texas:

  • Tradesman Plumber Limited License
  • Journeyman License
  • Master License
  • Plumbing Inspector License

Plumbers with the Tradesman Plumber Limited License can provide services for single-family dwellings or duplexes as long as they are supervised by master plumbers. They can also train apprentices and provide additional services under the direction of a licensed journeyman or master plumber.

With a Journeyman License, plumbers can work under the supervision of a master plumber and supervise apprentices or plumbers who hold Tradesman Plumber Limited Licenses.

Master plumbers serve as supervisors for lower-ranking plumbers.

Plumbers who acquire a Plumbing Inspector License can inspect the work of other plumbers.
