Do I need a permit to install a Level 2 EV charger?

Yes, most cities require a permit to install a Level 2 EV charger. You’ll want to ensure that your installation is correctly permitted for the following reasons:

1. Your family’s safety: Permits ensure the installation meets building code and safety requirements. Level 2 EV chargers are the highest load electrical appliance in most households. They can draw up to 11kW per hour (~4x the load of AC units), presenting a major safety risk if not installed correctly.
2. Home insurance: Without a permit, your homeowners insurance may deny your claim in the event of an accident.
3. Rebate eligibility: If your utility provider or AQMD offers rebates for Level 2 EV charger installation, you will need to provide proof of permit approval to receive the rebate.
