Searching for a parcel, step by step
- Open the official link. The viewer is built with ArcGIS Web AppBuilder; if a disclaimer pops up, accept it to continue.
- Use the search widget, usually in the upper left, to find a street address or parcel ID.
- Click a parcel to open its info window.
- The widget bar holds extras such as the layer list, basemap switcher, measure and print tools.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
