Plumbing license reciprocity by state · Pair verdict

Transfer a plumbing license from Ohio to California

Your Ohio license, California's rules. This page computes the pair the boards leave you to guess at — the full checker adds your license status and level.

A different door

No endorsement — experience credit toward the contractor route

California has no reciprocal contractor license. Out-of-state journey-level experience may be documented and verified toward the four-year requirement on the Certification of Work Experience form (CSLB), but the qualifier must still qualify and examine in California, subject to any exam-waiver provisions for persons already qualifying a California license.

California's journeyman gate, for the exam route: not published hours. One rule outranks the pair: a lapsed Ohio license endorses nowhere — reinstate at home first.

Rules as published by Contractors State License Board (CSLB), checked October 22, 2026. Confirm with the board before you apply.
