When you DON'T need a permit

Plugging a Level 1 (120V) EV charger into an existing outlet is NOT considered new electrical work and does not require a permit. This is the only permit-free EV charging method — just plug in and charge. Adds approximately 4-5 miles of range per hour.

When you DO need a permit

Level 2 (240V) EV charger installations require an electrical permit. This applies whether the charger is hardwired or installed via a new NEMA 14-50 outlet. The circuit must be sized at 125% of the EVSE nameplate amperage per NEC 625.41, with GFCI protection per NEC 625.54. California AB 1236 prohibits requiring a planning permit; AB 970 mandates approval within 20 business days for 1-25 chargers.

Installing a new NEMA 14-50 outlet for EV charging requires an electrical permit. Even though you may plug a portable EVSE into it, the outlet installation itself is new electrical work on a dedicated 50-amp circuit, which must meet NEC requirements for branch circuit sizing, GFCI protection, and grounding.

Upgrading the electrical service panel to support an EV charger requires a separate electrical permit and typically utility coordination for the service change. A 100A panel usually needs an upgrade to 200A to accept a full-speed Level 2 charger, or an Energy Management System (NEC 625.42) can be used as an alternative to avoid the service upgrade.

Estimated fee: $150 – $500
