Specifications for Electrical Vehicle Charging Readiness

At least 10% of parking spaces for new residential parking, or at least 1 parking space if less than 10 residential parking spaces will be provided, shall be pre-wired to allow for future Level 2 PEV charging system installation. Each of the subject parking spaces must be served by a 208/240 volt, 40 amp, grounded AC outlet, or there must be electric panel capacity and conduit to support future 208/240 volt, 40 amp outlets at each subject parking space. If a car lift is used to provide parking spaces, the pre-wiring may be part of the car lift or can be installed on the walls adjacent to the car lift, provided that future PEV charging systems could be used by vehicles on the car lift and the minimum 10% of parking spaces threshold is maintained. In multifamily projects at least one of the pre-wired parking spaces must be an accessible parking space, as defined by the California Building Code, or a standard parking space that can provide a 5' wide, 18' long access aisle and a path of travel to the building.

At new non-residential developments with over 20 parking spaces, at least 3% of the spaces shall be pre-wired to allow for future Level 2 PEV charging system installation. At least one of the pre-wired parking spaces must be an accessible parking space, as defined by the California Building Code, or a standard parking space that can provide a 5' wide, 18' long access aisle and a path of travel to the building.

Any Level 2 PEV charging systems installed at parking spaces will be counted toward the applicable pre-wiring requirement. All parking spaces with PEV charging systems may be counted toward the number of parking spaces required by the Zoning Ordinance.
