San Francisco’s Residential Energy and Water Conservation Ordinance requires an inspection and installation of basic conservation measures (low-flow fixtures, weatherization items) with a certificate of compliance at transfer. The property must also meet California’s requirements for smoke detectors, carbon monoxide alarms, and a properly strapped water heater. Sellers must provide a Natural Hazard Disclosure report identifying any mapped flood, fire, liquefaction, or fault zones. If there’s a known or suspected underground storage tank, that requires disclosure and potentially investigation.
