Plumber License from New York to New Hampshire: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board ↗
A plumbing license transfers from New York to New Hampshire by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board, verify your New York license, and meet New Hampshire's endorsement requirements. New Hampshire licenses a journeyman plumber by endorsement — without requiring its own plumbing examination — when the applicant holds an active, good-standing journeyman plumber license from one of 33 'qualifying jurisdictions' whose requirements OPLC deems substantially similar (RSA 310:17 / HB 594, rule Plc 313.34); applicants from any other state must qualify through New Hampshire's apprenticeship route and pass the New Hampshire plumbing examination.

Licensure by endorsement
New York is not among the states New Hampshire names for an automatic exam waiver, so this move runs on the New Hampshire Office of Professional Licensure and Certification (OPLC) — Mechanical Safety and Licensing Board's individual endorsement or equivalency review rather than a guarantee. New Hampshire licenses a journeyman plumber by endorsement — without requiring its own plumbing examination — when the applicant holds an active, good-standing journeyman plumber license from one of 33 'qualifying jurisdictions' whose requirements OPLC deems substantially similar (RSA 310:17 / HB 594, rule Plc 313.34); applicants from any other state must qualify through New Hampshire's apprenticeship route and pass the New Hampshire plumbing examination. Bring your New York 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.
