Los Angeles County Municipal Code § 4.106 Site Development

For each dwelling unit, install a listed raceway and a dedicated 208/240-volt branch circuit. The raceway shall not be less than trade size 1 (nominal 1- inch inside diameter). The raceway shall originate at the main service or subpanel and shall terminate into a listed attachment plug in close proximity to the proposed location of an EV charger. Raceways are required to be continuous at enclosed, inaccessible or concealed areas and spaces. The service panel and/or subpanel shall provide a 40-ampere 208/240-volt minimum dedicated branch circuit anda branch circuit overcurrent protective device.

(Ord. 2025-0052 § 5, 2025.)

The service panel or subpanel circuit directory shall identify the overcurrent protective device for future EV charging as "EV CAPABLE". The raceway termination location shall be permanently and visibly marked as "EV CAPABLE".

(Ord. 2025-0052 § 5, 2025.)

New development or alterations to existing developed sites shall comply with Chapter 12.84 of Title 12 of the Los Angeles County Code.

(Ord. 2025-0052 § 6, 2025.)

Roofing materials for conditioned and unconditioned spaces shall comply with the solar reflectance and thermal emittance requirements of this Section.

Exceptions:

Roof repair.

Roof replacement when the roof area being replaced is equal to or less than fifty (50) percent of the total roof area.

Installation of building-integrated photovoltaics.

Installation of a steep-sloped roof (roof slope > 2:12) in climate zone 16 on other than a low-rise multifamily building.

Additions resulting in less than 500 square feet of added roof area or less than fifty (50) percent of the total roof area, whichever is greater.

Roof construction that has a thermal mass over the roof membrane, including areas of vegetated (green) roofs, weighing at least 25 pounds per square foot.

(Ord. 2025-0052 § 7, 2025.)

Roofing materials shall have a minimum 3-year aged solar reflectance equal to or greater than the values specified in Table 4.106.6(1) and Table 4.106.6(2).

Solar reflectance values shall be based on the aged reflectance value of the roofing product or the equation in Section A4.106.5.1, if the CRRC testing for aged solar reflectance is not available.

(Ord. 2025-0052 § 7, 2025.)

Roofing materials shall have a CRRC initial or aged thermal emittance equal to or greater than the values specified in Table 4.106.6(1) and Table 4.106.6(2).

(Ord. 2025-0052 § 7, 2025.)

Roofing materials having a Solar Reflectance Index (SRI) equal to or greater than the values specified in Table 4.106.6(1) and Table 4.106.6(2) may be used as an alternative to compliance with the 3-year aged solar reflectance and thermal emittance values.

SRI values used to comply with this Section shall be calculated using the SRI Calculation Worksheet (SRI-WS) developed by the California Energy Commission or in compliance with ASTM E1980-01, as specified in the current California Energy Code. Solar reflectance values used in the SRI-WS shall be based on the aged reflectance value of the roofing product or the equation in Section A4.106.5.1, if the CRRC-certified aged solar reflectance is not available. Certified thermal emittance used in the SRI-WS may be either the initial value or the aged value listed by the CRRC.

Note: The Solar Reflectance Index Calculation Worksheet (SRI-WS) is available by contacting the Energy Standards Hotline at 1-800-772-3300, website at www.energy.ca.gov or by email at Title24@energy.ca.gov.
