BerkeleyThe City of Berkeley has several locally-specific requirements for building and construction projects, on top of the California Standards Building Code. Local regulations include gas shut-off valve requirements, energy reach codes, green building codes, and a natural gas prohibition for new buildings. Some regulations apply only in specific areas of Berkeley, including for hillside fire zones, creek buffer zones, and Environmental Management Areas.
