Last verified: 2026-07-21 · source: Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance ↗
A plumbing license transfers from New Mexico to Ohio by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance, verify your New Mexico license, and meet Ohio's endorsement requirements. Ohio waives its OCILB plumbing trade exam only for applicants who currently hold a South Carolina or West Virginia plumbing license obtained by examination (not by grandfathering or reciprocity); an out-of-state licensee who instead got their license by grandfathering or reciprocity must take both the Ohio plumbing exam and the Ohio Business and Law exam, and every other applicant must qualify with five years of trade experience and pass the Ohio plumbing exam.

Verdict
Licensure by endorsement
New Mexico is not among the states Ohio names for an automatic exam waiver, so this move runs on the Ohio Construction Industry Licensing Board (OCILB) — Ohio Department of Commerce, Division of Industrial Compliance's individual endorsement or equivalency review rather than a guarantee. Ohio waives its OCILB plumbing trade exam only for applicants who currently hold a South Carolina or West Virginia plumbing license obtained by examination (not by grandfathering or reciprocity); an out-of-state licensee who instead got their license by grandfathering or reciprocity must take both the Ohio plumbing exam and the Ohio Business and Law exam, and every other applicant must qualify with five years of trade experience and pass the Ohio plumbing exam. Bring your New Mexico 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.
