About the official source
It is a county-level map: Scott 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 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.

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.
