About the official source

This map is published by or for Oldham 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.

How to use the Oldham County viewer

  1. Open the link. It is an ArcGIS Instant App, a simple Esri template with a map and a few tools.
  2. Use the search box to jump to an address or place.
  3. Click a parcel to open its pop-up.
  4. Look for buttons along the edge of the map for layers, legend or basemaps.

Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.

A note on accuracy

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.
