Searching for a parcel, step by step
- Press the button above; an ArcGIS Experience Builder app opens in a new tab. Accept any splash or disclaimer screen.
- Search by address or parcel ID, or pan to the area.
- Select a parcel to view the information the publisher makes available.
- Explore the app's panels for layers, legends or printing.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
