About the official source
It is a county-level map: Pennington County or the company it hires keeps the parcel layer up to date. As of our October 2026 test, anyone could open it without signing in or paying.
Searching for a parcel, step by step
- Open the official link in a new tab.
- Accept any disclaimer, then look for a search box that takes street addresses, owners or parcel IDs.
- Zoom in and click a parcel to see its details.
- Use the map's layer controls to add aerials or other layers if they're offered.
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.
