Marin County supervisors voted in November 2022 to mandate that all new building construction must be all electric, eliminating fossil fuels from future business and residential buildings. In October 2024, supervisors approved a road map for completing the electrification process. The plan included “a neighborhood-scale electrification project, streamlining the permit process, and offering permit discounts to reduce the cost of appliance upgrades.”
Marin County mandated all-electric construction.
