Marin County updated its green building requirements on Tuesday, incorporating rules for electric vehicle support and revisiting its 2015 climate action plan.
The ordinance involves six changes, including more stringent energy efficiency requirements for houses larger than 4,000 square feet and the outlining of specific “green building” project tiers.
The Marin County Board of Supervisors replaced a chapter of its building code with the new ordinance on Tuesday.
The county will also require more electric vehicle charger capabilities so that residents can go electric, according to the ordinance.
The ordinance will add an all-electric building option for new construction and pursue goals to reduce greenhouse gas emissions.
The county set its standards in the 2015 Climate Action Plan, which it says are higher than California’s.
By 2020, Marin County wants to have greenhouse gas levels 30 percent lower than they were in 1990. The goal was 15 percent before Tuesday’s meeting.
