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.
Oakland FAQ
Can I install a gas range in a new Oakland home?
Generally no. Oakland reach code requires electric cooking in most new residential construction. Existing homes can replace appliances in kind, and limited exceptions apply for documented infeasibility cases.
Does the reach code apply to remodels?
Major remodels that significantly alter mechanical, plumbing, or electrical systems can trigger reach code provisions. Small renovations preserving existing gas service typically remain compliant under existing-building exceptions.
