Electric Vehicle (EV) Parking Requirement
All parking facilities that are available for use by the general public and include at least 100 parking spaces must designate at least one parking space specifically for EVs, provided that no parking spaces required by the Americans with Disabilities Act Accessibility Guidelines are reduced or displaced. Spaces must be clearly marked and equipped with EV charging stations. All EV charging stations installed must be Level 2 or direct current fast charging (DCFC) stations. An owner of multiple parking lots may designate and install EV charging stations in fewer parking spaces than required in one or more parking lots, as long as the owner meets the requirement for total number of aggregate spaces for all parking lots. A fee of $50-100 applies for non-EVs that park in spaces designated for EVs.
