Beginning next year, new residential and commercial construction in Marin must be all electric.
Marin County supervisors voted unanimously this week to approve an ordinance mandating the change effective Jan. 1. The supervisors voiced support for the move in October.
The ordinance also includes provisions designed to cut greenhouse gas emissions by reducing the use of natural gas. These include tougher energy efficiency requirements for additions, alterations and remodels, and increased access to electric vehicle charging stations for people living in multifamily housing.
Natural gas accounted for 26 percent of Marin’s countywide greenhouse gas emissions in 2020, second only to transportation, which caused 56 percent of the county’s emissions.
The stricter rules for additions, alterations and remodels apply to single-family homes over 750 square feet. Owners will be required to implement additional energy efficiency and electrifications beyond state code, but they will be given options for doing so. They will be allowed to select from a menu of energy efficiency and electrification measures.
The county is not contemplating all-electric requirements for renovations or remodels of existing buildings at this time, nor does it intend to require appliance swaps at the time of replacement, otherwise known as “time of burnout.”
The county’s ordinance also surpasses state requirements by requiring that multifamily housing residents be provided with access to electric vehicle charging stations.
Marin County is requiring that 15 percent of new multifamily units with parking spaces have Level 2 charging stations, while the state is requiring that only 5 percent of multifamily units with parking spaces be equipped with Level 2 chargers.
The county is requiring that the other 85 percent of units in multifamily developments have access to lower-power Level 2 electric vehicle receptacles that a car’s charging cable can plug into. The county’s ordinance mandates upgrading of electric vehicle charging capability at multifamily housing units when parking lots are modified.
The county’s Community Development Agency is working with Marin cities and towns in an effort to get them to develop similar policies. As of August, 60 California jurisdictions, including Fairfax and San Anselmo, had adopted ordinances requiring all-electric buildings for new construction.
