What makes 91311 distinct

  • Equestrian zoning - Chatsworth has horse-keeping pockets near the Santa Susana Mountains; if a horse property matters, verify the zoning (e.g., "A" or equestrian overlay) for the specific parcel.
  • Santa Susana Pass & rock formations - the dramatic sandstone outcrops on the city's north and west edges, with trail access.
  • Fire/hazard awareness - hillside and wildland-interface parcels can fall in a Fire Hazard Severity Zone; check the parcel's status and insurance availability before removing contingencies.
Two ZIP nuance: 91311 is the residential Chatsworth ZIP; 91313 is PO-box only. If a listing or record shows 91313, the home itself is still in the 91311 delivery area.
