Searching for a parcel, step by step
- Press the button above to open Beacon, the Schneider Geospatial parcel platform this county uses. Accept the usage terms if asked.
- Search by address, owner or parcel number, or zoom in and click a lot.
- From a parcel's pop-up, open the full record to see values, sales or building data where the county shares them.
- Switch layers on or off to compare parcels with aerials, zoning or other overlays.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
