Mandatory Electric Vehicle (EV) Charging Station Building Standards
At least one parking space, or 10% of parking spaces rounded to the next whole number, must be made-ready for Level 2 EV charging stations at all new buildings. Electrical capacity must accommodate the potential to serve a minimum of 20% of the total parking spaces with Level 2 EV charging stations. For assembly, education, or mercantile buildings, the requirements apply only to employee parking spaces. Buildings classified as utility or miscellaneous and some residential buildings are exempt from these requirements. Additional terms and conditions apply.
