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
