Implementation
For multi-family residential projects, require that 100 percent of parking spaces are EV Ready[1]. For commercial projects, require that a specific proportion of total required parking spaces support future EVSE charging, consistent with the 2022 CALGreen Tier 2 (Section A5.106.5.3.2) code. The measures shall also include signage requirements in the building code for EV charging facilities for both wayfinding and parking restrictions. The County will periodically re-assess and update reach codes in response to updates to the building code.
Timeframe: Near term
GHG Reduction Potential: Not quantified
Sector: Vehicles - On-Road
Target Indicator: Amendment of building code and development standards to require EVSE installations at multi-family and commercial projects no later than 2023. This code amendment can occur concurrently with the reach codes for building energy specified in GHG-05 and GHG-07.
