About the official source
This map is published by or for Custer County itself, so it reflects the local parcel layer rather than a third-party copy. Our October 2026 check found the map open to the public, with no account or payment needed.
Searching for a parcel, step by step
- 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.

Before you rely on the lines
Keep in mind that a GIS parcel layer is a tax map, not a survey. For exact boundaries, look at the recorded deed and plat or hire a licensed land surveyor.
