Residential EV Charging

An electric vehicle (EV) charging station supplies electric energy for the recharging of electric vehicles or plug-in hybrids. Usually, an EV owner plugs in when returning home, and the car battery recharges overnight. For details about residential charging stations, including charging in the right-of-way, review the Residential Electric Vehicle Charging Permitting Guide.

New Requirements for Electric Vehicle Charging
 A State law, effective October 1, 2023, requires the construction of new housing units (single-family detached houses, duplexes, and townhouses subject to the International Residential Code), that include a separate garage, carport, or driveway, to include either an electrical vehicle supply equipment (EVSE) parking space installed from the electrical panel to the parking space capable of providing at least Level 2 charging (minimum of 208 Volts), or an electrical vehicle (EV) ready parking space that has electrical panel capacity and full circuit installation of a minimum 40-ampere, 208/240-volt circuit, raceway wiring, a NEMA 14-50R receptacle, and circuit overcurrent protection devices. Construction documentation must include the location of the parking space when applying for the building permit. The associated electrical permit must include details of the electrical vehicle charging. If you have questions about this new requirement, contact DPS at 240-777-0311 or MC 311.
