Contractor License from California to Connecticut: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Connecticut Department of Consumer Protection - Occupational and Professional Trade Licensing ↗
A contractor license transfers from California to Connecticut by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Connecticut Department of Consumer Protection - Occupational and Professional Trade Licensing, verify your California license, and meet Connecticut's endorsement requirements. CGS 20-333a lets the DCP Commissioner grant a trade license (electrical, plumbing, heating/piping/cooling, sheet metal, etc.) WITHOUT examination to a currently-practicing licensee who holds a substantially-similar-or-higher license from another state, but ONLY where that state grants Connecticut licensees the same exam-free treatment (mutuality).

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