Quick Answer: Yes, in California a homeowner-occupant can perform electrical work on their own primary residence under the owner-builder exemption, but they must: (1) Apply for and obtain an electrical permit from the San José Building Division before starting work; (2) Be the owner-occupant (not a landlord doing work on a rental); (3) Complete all work themselves — they cannot hire unlicensed workers to do the actual work; (4) Pass all required inspections. The work must comply with the California Electrical Code (CEC) and NFPA 70 (National Electrical Code). Common owner-builder electrical projects that pass inspection: adding outlets, installing light fixtures, running new circuits. More complex work (panel upgrades, service entrance, new subpanels, EV charger installation on a new circuit) is often better done by a licensed electrician (C-10 license) — both for safety and because the complexity often exceeds DIY skills. Importantly, if you sell the home within 1 year of permitted owner-builder work, you must disclose this to buyers.
