Finding a property on this map
- Open the link to the Beacon site from Schneider Geospatial. If a terms or disclaimer window appears, agree to it to continue.
- Use the search bar to look up a street address, an owner's name or a parcel ID. Beacon sites usually also have a dedicated property search page.
- Click a lot on the map and then open its report for assessment and property details.
- Use the layer and basemap controls to add aerial photos or other layers the county publishes.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

A note on accuracy
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.
