§ 5.106

Nonresidential buildings (excluding hotels and motels) and nonresidential portions of mixed-use buildings: EV capable spaces shall be provided as specified below and per the following requirements:

1. For retail uses: 15% of parking spaces shall be EV Capable. For Places of Religious Worship: 10% of parking spaces shall be EV Capable. For all other nonresidential buildings (excluding hotels and motels) and nonresidential portions of mixed-use buildings: 35% of parking spaces shall be EV Capable.

2. Raceways complying with the California Electrical Code and no less than 1-inch (25 mm) diameter shall be provided and shall originate at a service panel or a subpanel(s) serving the area and shall terminate in close proximity to the proposed location of the capable space and into a suitable listed cabinet, box, enclosure or equivalent. A common raceway may be used to serve multiple capable spaces.

3. A service panel or subpanel(s) shall be provided with panel space and electrical load capacity for a dedicated 208/240 volt, 40-ampere minimum branch circuit for each capable space, with delivery of 30-ampere minimum to an installed at each

4. The electrical system and any on-site distribution transformers shall have sufficient capacity to supply full rated amperage at each capable space.

5. The service panel or subpanel circuit directory shall identify the overcurrent protective device space(s) as "EV CAPABLE". The raceway termination location shall be permanently and visibly marked as "EV CAPABLE."

Calculations for the required minimum number of spaces shall all be rounded up to the nearest whole number.

Construction plans and specifications shall demonstrate that all raceways shall be a minimum of 1" and sufficient for installation at all required EVCS; electrical calculations shall substantiate the design of the electrical system to include the rating of equipment and any on-site distribution transformers, and have sufficient capacity to simultaneously charge EVs at all required EVCS including EV Capable spaces; and service panel or subpanel(s) shall have sufficient capacity to accommodate the required number of dedicated branch circuit(s) for the future installation of the EVCS.

• (c) 2025 California Green Building Standards Code Chapter 5, Nonresidential Mandatory Measures, Division 5.1, Planning and Design, Section 5.106.5.3.2 (Electric vehicle charging stations (EVCS)) is hereby amended to read as follows, but Sections 5.106.5.3.2.1 through 5.106.5.3.2.4.1 shall remain unchanged:

Nonresidential buildings (excluding hotels and motels) and nonresidential portions of mixed-use buildings: In addition to the EV Capable Space requirements of Section 5.106.5.3.1, nonresidential buildings (excluding hotels and motels) and nonresidential portions of mixed-use buildings shall comply with the following:

1. For retail uses: an additional 15% of parking spaces shall be provided with EVCS. For Places of Religious Worship: an additional 10% of parking spaces shall be provided with EVCS. For all other nonresidential buildings (excluding hotels and motels) and nonresidential portions of mixed-use buildings: an additional 35% of parking spaces shall be provided with EVCS.

2. Required EVCS may be provided in any combination of Level 2 and Direct Current Fast Charging (DCFC), except that at least one Level 2 EVSE shall be provided.

Notes:

1. Calculations for the required minimum number of spaces equipped with EVCS shall be rounded up to the nearest whole number.

2. ALMS may be installed to increase the number of EV chargers or the amperage or voltage beyond the minimum requirements in this code. The option does not allow for installing less electrical panel capacity than would be required without ALMS.

• (d) 2025 California Green Building Standards Code Chapter 5, Nonresidential Mandatory Measures, Division 5.1, Planning and Design, Section 5.106.5.3.3 (Use of Automatic Load Management System (ALMS)) is hereby amended to read as follows:

5.106.5.3.3. Use of Automatic Load Management Systems (ALMS) ALMS shall be permitted for EVCS. When ALMS is installed, the required electrical load capacity specified in Section 5.106.5.3.1 and Section 5.106.5.3.2 for each EVCS may be reduced when serviced by an EVSE controlled by an ALMS. Each EVSE controlled by an ALMS shall deliver a minimum 30 amperes to an EV when charging one vehicle and shall deliver a minimum 3.3 kW while simultaneously charging multiple EVs.

• (e) 2025 California Green Building Standards Code Chapter 5, Nonresidential Mandatory Measures, Division 5.1, Planning and Design, Section 5.106.5.3.5 (Electric vehicle charging station signage) is hereby amended by adding the following text immediately following Section 5.106.5.3.5:

5.106.5.3.5.1 Raceway Identification. The raceway termination location shall be permanently and visibly marked as "EV Ready".
