New York to Louisiana: journeyman plumber license reciprocity

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 annual continuing education (hours for journeymen are not stated on the pages reviewed). 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; the transition was under public discussion in late 2026 and no changed requirements had been published.

New York has no statewide plumber licence at any level: the Department of State's Division of Licensing Services regulates 35 occupations and none of them is plumber, plumbing contractor, journeyman plumber or master plumber. Journeyman-level plumbing credentials therefore exist only where a city or county ordinance creates them, and they are not interchangeable. New York City's Department of Buildings issues a Journeyman Plumber / Fire Suppression Piping Installer registration (employees work under a licensed Master Plumber; the registration is not an independent contracting licence). Westchester County issues a Journey-Level plumber licence (exam application $25, licence and renewal $75) that is required to work as a plumber anywhere in the county, including Yonkers. Rochester publishes a Plumbing Licensing programme on its Licensed Trades page but does not list class names or fees on that page. An out-of-state journeyman plumber licence has no state-level recognition in New York; the arriving worker must satisfy the city or county where the work will be done, and in New York City that typically means working under a licensed Master Plumber while holding (or obtaining) the city journeyman registration.
