The Green Homes California program, led by the U.S. Green Building Council California (USGBC-CA), offers a comprehensive approach to enhancing energy efficiency, electrification, and health in both single-family and multifamily residences, particularly in communities vulnerable to climate change. This initiative provides resources for homeowners, tenants, and property managers to implement sustainable upgrades—such as installing heat pump systems, induction cooktops, and electric vehicle (EV) charging stations—with the goal of reducing utility costs and improving indoor air quality. Participants benefit from whole-building assessments, assistance with utility rebates, and resident engagement programs available in both English and Spanish.

The program also offers digital tools like the Menu of Efficiency & Electrification, which provides cost-saving strategies and incentive pathways tailored for multifamily properties. Additionally, toolkits such as the Resident Toolkit and the Greening Affordable Housing Toolkit offer practical advice for low- to no-cost improvements, promoting healthier living environments. Case studies from areas like the Eastern San Fernando Valley and Wilmington highlight successful implementations of heat pump retrofits and community engagement efforts, demonstrating the program's impact on reducing emissions and enhancing resilience in underserved neighborhoods.
