Berkeley FAQ
Can Berkeley still ban gas in new construction?
Not directly. The 9th Circuit ruled in California Restaurant Association v. Berkeley that federal law preempts the 2019 ban. Berkeley now uses performance-based energy and emissions standards instead.
Are solar panels required on new homes?
Yes. California statewide rules under CALGreen and Title 24 require new low-rise residential buildings to install solar PV, with limited exceptions for shaded sites and alternative compliance paths.
