Performing a Search – Locate a Parcel Using APN or Address

There are two primary ways to identify a parcel or area of interest. You can Search by Address or by APN:

search bar with the following drop down choices: All, Search by Address, Search by APN

Enter an Address or APN & select the magnifying glass icon:

  • Search by Building Address requires Street #, Street Name, City or Zip code (e.g. 15000 Hwy 1, Valley Ford or 15000 Hwy 1, 94972)
  • Search by Street Range does not require City or Zip code (e.g. 15000 Hwy 1).   The search result will place a marker on the street centerline. This method of address search allows greater flexibility when City or Zip code is unknown.  

The map viewer will zoom-in & center the map on selected parcel. The selected parcel’s profile panel will automatically open. Close using X in upper-right corner.

To unselect parcel, select the "X":
