Cities and counties in California serve as guiding lights as the state navigates a transition from gas to clean-energy buildings. Motivated by the climate crisis, worsening air pollution, escalating gas rates, and safety risks from gas, a new cohort of local government leaders is emerging in California. Over 60 cities and counties across the state are considering policies to support all-electric new construction.
This blog summarizes the cities and counties that have already adopted gas-free buildings commitments or electrification building codes (i.e., “reach codes” that go beyond the statewide building code) and is regularly updated to reflect the latest wins in California. Ordinance language is also linked below.
To urge your city council members to be climate leaders and to create a gas-free future for our homes and buildings, please sign this petition. To get more involved in the campaign, please sign up here for updates on what is happening in your city. For more information, or any tips/edits to the cities and counties on this list, please contact Sierra Club's California Press Secretary Sander Kushen at sander.kushen@sierraclub.org.

City and county leadership is essential not just for local climate action but also to convince the California Energy Commission to require or at least support all-electric new construction in the statewide building code (Title 24).
The CEC updates Title 24 every three years. The 2022 version of Title 24 was adopted on December 14, 2021 and will go into effect on January 1st, 2023. The next iteration of Title 24 will come out in 2025, giving Californians plenty of time to push for an even stronger rule! All of this community and city support for more-ambitious building codes sends a strong signal to the CEC to align the statewide building code with climate science and require all-electric new construction. Californians deserve nothing less.
