Moving to Louisiana as a journeyman plumber: every state's rule

Louisiana licenses Journeyman Plumbers statewide through the State Plumbing Board of Louisiana (SPBLA), which also registers apprentices and licenses Residential Plumbers, Master Plumbers, natural gas fitters and medical gas and WSPS endorsements. A new in-state applicant must be a registered apprentice with 7,000 hours (indentured, in a Louisiana Workforce Commission-approved program) or 8,000 hours (unindentured) of supervised plumbing work documented by payroll records or W-2s, file a notarized application with $135 ($125 exam + $10 processing), and pass a Board-administered 80-question, 3-hour written exam on the 2021 IPC/IRC plus a 1-hour practical, scoring at least 70% in each category. The first license costs $50; licenses expire December 31 each year and renewal requires 3.5 hours of continuing professional education each year. A journeyman works under a licensed Louisiana Master Plumber and must be employed by a licensed master company for the license to be 'workable'. The Board has signed journeyman reciprocity agreements only with Texas and Arkansas; a plumbing license from any other state qualifies the holder to sit the Louisiana journeyman exam without Louisiana apprentice registration, provided the origin state required at least 8,000 on-the-job hours. Act 908 of the 2026 session transfers plumbing licensing to the Louisiana State Licensing Board for Contractors on January 1, 2027; existing licenses carry over, and the Act lowers the experience needed for the journeyman license to 2,500 hours of verified apprentice work.
