Plumber License from Illinois to Louisiana: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: State Plumbing Board of Louisiana (SPBLA) ↗
A plumbing license transfers from Illinois to Louisiana by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the State Plumbing Board of Louisiana (SPBLA), verify your Illinois license, and meet Louisiana's endorsement requirements. Louisiana waives its journeyman plumber examination only for applicants licensed as journeyman plumbers in Arkansas or Texas under the State Plumbing Board's bilateral reciprocity agreements (license held in good standing and obtained by examination); every other out-of-state plumber must pass the Louisiana written and manual journeyman exam, though a valid out-of-state plumbing license may be submitted to qualify to sit for it.

Verdict
Licensure by endorsement
Illinois is not among the states Louisiana names for an automatic exam waiver, so this move runs on the State Plumbing Board of Louisiana (SPBLA)'s individual endorsement or equivalency review rather than a guarantee. Louisiana waives its journeyman plumber examination only for applicants licensed as journeyman plumbers in Arkansas or Texas under the State Plumbing Board's bilateral reciprocity agreements (license held in good standing and obtained by examination); every other out-of-state plumber must pass the Louisiana written and manual journeyman exam, though a valid out-of-state plumbing license may be submitted to qualify to sit for it. Bring your Illinois license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
