Exception: Areas of parking facilities served by parking lifts, including but not limited to, automated mechanical-access open parking garages as defined in the California Building Code; or parking facilities otherwise incapable of supporting electric vehicle charging.

   b. Multifamily parking facilities with unassigned parking. Where dwelling units are provided with unassigned parking spaces equal to or greater than the number of dwelling units, 10% of the total number of parking spaces shall be equipped with Level 2 EV chargers. At least fifty (50) percent of the required EV chargers shall be equipped with J1772 or J3400 connectors. 40% of the total parking spaces shall be Level 2 EV Ready (rounded up to the next whole number) and the remaining shall be at least one low power Level 2 EV charging receptacle. 1. Where the total number of dwelling units exceeds the number of unassigned parking spaces, 10% of the total number of parking spaces shall be equipped with Level 2 EV chargers. At least fifty (50) percent of the required EV chargers shall be equipped with J1772 connectors. 40% of the total shall be Level 2 EV Ready (rounded up to the next whole number) and the remaining unassigned parking spaces shall be provided with one low power Level 2 EV charging receptacle. Exception: Areas of parking facilities served by parking lifts, including but not limited to, automated mechanical-access open parking garages as defined in the California Building Code; or parking facilities otherwise incapable of supporting electric vehicle charging.

   c. Multifamily parking facilities with assigned and unassigned parking. Where multifamily buildings are provided with both assigned and unassigned parking spaces equal to or greater than the number of dwelling units, 10% of the total number of parking spaces shall be equipped with Level 2 EV chargers. At least fifty (50) percent of the required EV chargers shall be equipped with J1772 or J3400 connectors. 40% of the total parking spaces shall be Level 2 EV Ready (rounded up to the next whole number) and the remaining shall have at least one low power Level 2 EV charging receptacle.

   d. Receptacle power source. EV charging receptacles in multifamily parking facilities at assigned parking spaces shall be provided with a dedicated branch circuit connected to the dwelling unit's electrical panel, unless determined as infeasible by the project builder or designer and subject to concurrence of the local enforcing agency.

Exception: Areas of parking facilities served by parking lifts, including but not limited to, automated mechanical-access open parking garages as defined in the California Building Code; or parking facilities otherwise incapable of supporting electric vehicle charging.

e. Multifamily parking facilities with unassigned or common use parking. 25% of the total number of parking spaces shall be equipped with Level 2 EV chargers. At least fifty (50) percent of the required EV chargers shall be equipped with J1772 or J3400 connectors. 40% of the total parking spaces shall be Level 2 EV Ready (rounded up to the next whole number) and the remaining shall have at least one low power Level 2 EV charging receptacle.

f. Ev charger connectors. EV chargers shall be equipped with J1772 or J3400 connectors.

g. An automatic load management system (ALMS) may be used to reduce the maximum required electrical capacity to each space served by the ALMS. The electrical system and any on-site distribution transformers shall have sufficient capacity to deliver at least 3.3 kW simultaneously to each EV charging station (EVCS) served by the ALMS. The branch circuit shall have a minimum capacity of 40 amperes, and installed EV chargers shall have a capacity of not less than 30 amperes.

h. Receptacle configurations. 208/240V EV charging receptacles shall comply with one of the following configurations:

1. For 20-ampere receptacles, NEMA 6-20R.

2. For 30-ampere receptacles, NEMA 14-30R

   3. For 50-ampere receptacles, NEMA 14-50R

      Notes:

      1. ALMS may be installed to decrease electrical service and transformer costs associated with EV Charging Equipment subject to review of the authority having jurisdiction.
      2. Installation of Level 2 EV Ready Spaces above the minimum number required level may offset the minimum number low power Level 2

   EV Ready Spaces required on a 1:1 basis. 3. If a building permit applicant provides documentation detailing that the increased cost of utility service or on-site transformer capacity would exceed an average of $4,500 for each parking spaces with Level 2 EV Ready Spaces and Level 1 EV Ready Spaces, the applicant shall provide EV infrastructure up to a level that would not exceed this cost for utility service or on-site transformer capacity. 4. All accessible parking spaces for covered newly constructed multifamily dwellings shall provide low Level 2 EV Ready Space or Level 2 EV Ready Spaces.

5. The requirements apply to multifamily buildings with parking spaces including: a) assigned or leased to individual dwelling units and b) unassigned parking spaces.

(e) 2025 California Green Building Code Section 4.106.4.2.6 (Hotels and motels) is hereby amended to read as follows:

   chargers. At least 50% of the required EV chargers shall be equipped with J1772
   or J3400 connectors. Forty (40) percent of the total number of parking spaces
   shall be equipped with low power Level 2 EV charging receptacles. The
   remaining parking spaces shall be provided with a least Level 1 EV Capable.

   Exception: Areas of parking facilities served by parking lifts, including but
   not limited to automated mechanical-access open parking garages as defined
   in the California Building Code; or parking facilities otherwise incapable of
