Staff notes that existing properties with gas infrastructure can maintain the existing infrastructure, and most additions to these properties could continue to include gas. Specifically, alterations to existing properties with gas (e.g., partial demolition and rebuild of an existing home) can continue include gas if the alteration is less than 50 percent of the total existing building size. Large-scale alterations, involving 50 percent or more of the existing building, would be required to convert to all-electric. Further, any construction of new buildings (e.g., a new detached ADU or pool house) on the property would need to be constructed all-electric. The redlines to Part 11, Title 24 for building electrification are included as Exhibit B of Attachment 1. It is noted that certain types of buildings such as hospital buildings, skilled nursing facilities, and intermediate care facilities are the jurisdiction of the Office of Statewide Health Planning and Development (OSHPD)and not subject to the City's adopted codes. Electric Vehicle Charging Infrastructure Given the significant contribution of transportation-related emissions to the overall GHG inventory, a fundamental shift in the types of cars driven by Californians, and the fuel they use, is necessary to meet California's health-based air quality standards and greenhouse gas emission reduction goals. Recognizing this, Governor Newsom's recent Executive Order N-79-20, realized through the State of California Air Resource Board (CARB)'s Advanced Clean Cars II rule, establishes that 100 percent of new cars and light trucks sold in the state will be zero-emissions vehicles by 2035. Increasing access to reliable electric vehicle charging stations at home and at work is key to increasing EV adoption. Lack of access to EV charging infrastructure at home, and particular at multi-family dwellings, is a major hurdle to EV ownership. As such, 2022 CALGreen (Part 11) within Title 24 outlines requirements for electric vehicle charging. The proposed reach codes would have more stringent requirements than the 2022 CALGreen, and so a comparison is provided of those "base" requirements, versus the reach codes in Tables 1, 2 and 3 below for different types of development. The tables reference various types of EV infrastructure, principally related to the speed of charging and necessary electricity supply to achieve those speeds, and EV "readiness" based on the components that would be installed at time of construction. EV charging infrastructure is categorized into three major types: • Level 1: 120V, charge time 3-5 miles per hour • Level 2: 240V, charge time 12-40 miles per hour2 • Level 3: 480V, 150+ miles per charging hour (typically, an EV can get 80% full charge in 20 minutes) Level 2 typically includes a 40-amp circuit whereas low power level I is a 20-amp circuit Page 5 of 10
