The Legal Answer
California allows homeowners to perform electrical work on their own primary residence, including a Level 2 EV circuit — but a permit is still required, an inspection is still required, and the work must meet the California Electrical Code. If any of those steps are skipped, the installation is illegal regardless of who did it.
The Practical Answer
EV circuits are 40–60 amps of continuous 240-volt load — the largest continuous circuit in most homes. A wrong torque on a breaker lug or a mis-terminated conductor can start a fire months later. Most Tesla, ChargePoint, and Wallbox warranties require professional installation for full coverage.

Frequently Asked Questions
What happens if I skip the permit?+
The installation is unpermitted. It shows up in home sale inspections, may void insurance in a fire, and the city can require removal or retroactive permitting at your expense.
