Searching for a parcel, step by step
- Click the button above and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
- Search by street address, owner or parcel ID if the search box offers those options.
- Click a lot on the map to read its attributes.
- Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.
