District Lookup

Find out which of Marin County's five districts represents your property. You can enter either a parcel number (i.e. 123-456-78) or an address (i.e. 100 Main St, City). If the property is a vacant lot, you must enter the parcel number.

  1. You can look up a parcel by address or by Assessor Parcel Number (e.g., 123-456-78), including leading zeros.
  2. Begin typing the full address or Assessor Parcel Number, including leading zeros. A drop down with matching addresses or Assessor Parcel Numbers will appear.
  3. If the address or Assessor Parcel Number you are searching for appears in the drop down, select it, then click the "Submit" button.
