Searching for a parcel, step by step
- Open the link. It is an ArcGIS Instant App, a simple Esri template with a map and a few tools.
- Use the search box to jump to an address or place.
- Click a parcel to open its pop-up.
- Look for buttons along the edge of the map for layers, legend or basemaps.
If an address search comes up empty, try the parcel number from a tax bill or deed instead, or click the lot on the map.
