A Natural Hazard Disclosure (NHD) report identifies whether a property sits within state-designated hazard zones, including flood zones, fire hazard severity zones, earthquake fault zones, seismic hazard zones (such as liquefaction or landslide areas), and dam inundation zones. California law requires sellers to provide this to buyers. In San Francisco, liquefaction zones and hillside areas are the most relevant. The NHD itself is informational, but it often prompts additional investigation, especially for older construction in mapped zones.
