About the official source
It is a county-level map: Marshall County or the company it hires keeps the parcel layer up to date. When we tested the link in October 2026 it opened with no login and no fee.
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.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.

Maps vs. surveys
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.
