Understanding Parcel Report Details

  • APN or Assessor’s Parcel Number - number assigned to parcels of real property by the county tax assessor of a particular jurisdiction for purposes of identification and record-keeping.

In these cases, a “CANNOT ASSESS…” will be the value. Please see page 3 “Gross vs. net lot area” in the Single Family Zoning Technical Manual or contact the Planner on Duty at Development Services for more information. 
  • Net Lot Size for condominiums or “Air Parcels” - In cases where the property is in an ownership multifamily development where individuals own a unit, such as condominiums or properties with homeowners associations, a CANNOT ASSESS DUE TO PARCEL TYPE will be displayed.
