Do you need a license to work as a plumber in Louisiana?
Yes. In Louisiana, plumbing work requires a residential plumber limited, journeyman plumber or master plumber license from the State Plumbing Board, a journeyman may work only while employed by a master plumber, and a business may hold itself out as doing plumbing only if it employs a master plumber. Plumbing as defined in the chapter does not include work done by an individual on his own personal residence. A plumbing contractor on a project of $10,000 or more also needs a plumbing classification from the State Licensing Board for Contractors, which does not excuse compliance with the State Plumbing Board’s licensing. This is La. R.S. 37:1361, 37:1367, 37:1377, 37:2150.1, 37:2156.1.
