The Map/Block/Lot search allows you to search for owners of a specific parcel, or a group of related parcels.  If you know a property’s map, block, lot, or unit, enter them in the appropriate fields.  You do not have to fill in all of the fields.  After you are done entering the information, press the Enter key or click on the search icon on the right.  The search will only match on the fields that are filled in.
