Zoning Report

San Bernardino, CA Zoning

San Bernardino’s publicly available city materials show a traditional zoning framework with multiple residential districts ranging from estate lots to high-density multifamily, plus at least one student-housing overlay tied to California State University San Bernardino. The available source set for this report is incomplete, but it does confirm that the city regulates use, density, and development standards by zone and publishes its Development Code through the city website. Flood-related constraints should also be checked because FEMA mapping is available and floodplain regulation is commonly relevant, although the provided city source set does not include a complete city flood overlay chapter.
