Please Note: The County, City, and School district boundary files are included for reference only. Only the specific county, city, or school can determine whether a specific property or portion of a property is or is not within their boundary.

GIS data becomes especially valuable if it is linked to data. The Parcels in the shape file above contain a linking field (TAXPIN) which can be used to connect the parcel graphic with the account information (AAAA) available on our Free Downloads page.
