Multi-family buildings, classified as Use Group R2 under Table 406.2.9, must provide EV Ready parking spaces on a sliding scale: one space for lots of 5 to 20 spaces, two EV Ready spaces plus one EVSE Installed space for 21 to 49 spaces, and for 50 or more spaces, 10 percent of all spaces EV Ready and 2 percent EVSE Installed, effective January 1, 2025. Equipment must meet UL 2594 and UL 2202 listing standards.
