Contractor License from Ohio to California: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: California Contractors State License Board (CSLB) ↗
A contractor license transfers from Ohio to California by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the California Contractors State License Board (CSLB), verify your Ohio license, and meet California's endorsement requirements. California's CSLB waives the trade (craft) examination for an applicant who has held an active license in good standing for the previous five years in a reciprocal state — Arizona and Nevada (broad classification coverage) or Louisiana, Mississippi, and North Carolina (General Building 'B' only, requiring the NASCLA exam). The Law and Business examination is always required. Holders of the NASCLA Commercial General Builder exam may also waive the trade exam for the 'B' classification..

Verdict
Licensure by endorsement
California does not have a trade agreement covering Ohio for the selected trade, so this move runs on California's case-by-case endorsement process. If you do commercial general-building work, check whether California accepts the NASCLA exam — passing it once can replace the trade exam here and in about fourteen other states. Electricians should check California's NERA status.
