Louisiana Licensing Requirements for Plumbers

There are two options for getting started in the plumbing profession in Louisiana. First, you can enroll in an apprenticeship program approved by the state’s Plumbing Board. As an alternative, you can gain experience working with a licensed plumber. You need to work for five years or a total of 8,000 hours to advance your career past this stage. To join an apprenticeship program or work for a plumber, you must be at least 16.

There are several types of licensing classifications in Louisiana, including:

  • Journeyman plumbers
  • Master plumbers
  • Tradesman plumbers
  • Medical gas plumbers

To get your journeyman’s license, you must complete an approved apprenticeship or meet the equivalent work experience requirement. In addition, you must pass your journeyman plumber exam. To take the exam, you must submit an application signed by three licensed plumbers.

Master plumbers can operate their own businesses in Louisiana. To earn your master’s license, you must first get your journeyman’s license. In addition, you must hold a journeyman’s position under a master plumber for at least five years.

In Louisiana, tradesmen are residential plumbing repair specialists. They can only work under the supervision of a master plumber. A tradesman’s license does not allow you to carry out tasks reserved for journeymen.

Medical gas plumbers install and repair specialized gas systems for healthcare facilities. To perform this work in Louisiana, you must get certified in a state-approved training course. You must also go through an application process.

Plumbing Apprenticeships in Louisiana

Apprenticeships are common in the skilled trade industries. That includes the plumbing industry. Depending on where you live, laws or regulations may include formal guidelines for all plumbing apprentices. Such guidelines may only apply to some cities or counties. However, they may also apply to the entire state.

In Louisiana, rules for plumbing apprentices are statewide. To begin with, all apprentices must register with the State Plumbing Board. Once you’re registered, you have a couple of options for advancing from an apprenticeship to a higher status as a plumber. One option is to seek work with a plumber already licensed by the state. Alternatively, you can sign on for a state-approved apprenticeship program. Whichever option you choose, you must either:

  • Gain a minimum of 8,000 hours of experience
  • Spend five years as at the apprentice level

How can you find a suitable apprenticeship program? One important resource is Apprenticeship Louisiana. This organization maintains a database of businesses approved for apprentice training.
