How to Obtain a Louisiana Plumbing License?

You are here:

Have you decided to start your profession as a plumber in Louisiana?

To conduct the plumbing profession lawfully, plumbers in Louisiana are required to get a state-issued license. For that, the State Plumbing Board of Louisiana has specific criteria that must be met to finish a plumbing apprenticeship program and pass an examination. 

Additionally, in Louisiana, if you are performing specialty services whose value exceeds $10,000 in material and labor, then there is a need for you to be a licensed plumbing contractor. The Louisiana State Licensing Board for Contractors (LSLBC) is responsible for issuing commercial contractor licenses.

To help you get a Louisiana plumbing license, we will go through all the necessary licensing requirements.
