Contractor License from California to Idaho: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Idaho Division of Occupational and Professional Licenses (DOPL) — Electrical and Plumbing Boards ↗
A contractor license transfers from California to Idaho by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Idaho Division of Occupational and Professional Licenses (DOPL) — Electrical and Plumbing Boards, verify your California license, and meet Idaho's endorsement requirements. Idaho (DOPL) reciprocates the journeyman ELECTRICAL license of 12 states if the applicant tested for the current license, held it at least one year, and shows 4 years of schooling plus OJT (Wyoming also master). Journeyman PLUMBING reciprocity is limited to Montana, Oregon, and Washington. HVAC has no reciprocity, and general contractors only register (no exam, no reciprocity)..

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