Searching for a parcel, step by step
- Press the button above to open the county's own web map.
- Search for the property or pan and zoom to it.
- Click the lot to bring up what the county publishes about it.
- Look for print or measure tools if you need a quick map or rough size.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
