Minimum number of spaces Projects must design EV-ready parking for the minimum number of spaces, per Table 2. Percentage thresholds only apply if the minimum number of EV-ready spaces meets or exceeds those listed in Table 2.

Commercial projects require EV-ready spaces for at least 10% of the total parking spaces and no fewer than 10 spaces. Parking capacity must include all existing and new off-street parking spaces that are leased or owned by the project, including parking that is outside the project boundary but is used by the project. On-street parking in public rights-of-way is excluded from these calculations. Use Equation 3 to determine the number of spaces required to meet the 10% threshold. If the equation does not result in a whole number, round up to the next whole number.

Equation 3. Commercial minimum EV-ready parking

𝑀𝑖𝑛. # 𝑜𝑓 𝐸𝑉-r𝑒𝑎𝑑𝑦 (c𝑜𝑚𝑚𝑒𝑟𝑐𝑖𝑎𝑙) = 𝑇𝑜𝑡𝑎𝑙 # 𝑜𝑓 𝑝𝑎𝑟𝑘𝑖𝑛𝑔 𝑠𝑝𝑎𝑐𝑒𝑠 𝑥 0.10 ≥10 𝑠𝑝𝑎𝑐𝑒𝑠

Residential projects require EV-ready spaces for at least 20% of the total parking spaces and no fewer than 20 spaces. Determine the minimum number of spaces using Equation 4.

Equation 4. Residential minimum EV-ready parking

𝑀𝑖𝑛. # 𝑜𝑓 𝐸𝑉-r𝑒𝑎𝑑𝑦 p𝑎𝑟𝑘𝑖𝑛𝑔 (r𝑒𝑠𝑖𝑑𝑒𝑛𝑡𝑖𝑎𝑙) = 𝑇𝑜𝑡𝑎𝑙 # 𝑜𝑓 𝑝𝑎𝑟𝑘𝑖𝑛𝑔 𝑠𝑝𝑎𝑐𝑒𝑠 × 0.20 ≥20 𝑠𝑝𝑎𝑐𝑒𝑠

Combining Options 1 and 2 LTc5: Electric Vehicles only rewards teams up to two points. Therefore, when combining options, projects must meet one point for Option 1 and one point for Option 2.

Projects cannot double count spaces with installed EVSE as an EV-ready space. Each parking space must meet the characteristics of an EV-ready space or a space with an available EVSE.
