Quick facts

Where the parcel data comes from

It is a county-level map: Jefferson 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.

Finding a property on this map

1. Open the official link in a new tab.
2. Accept any disclaimer, then look for a search box that takes street addresses, owners or parcel IDs.
3. Zoom in and click a parcel to see its details.
4. Use the map's layer controls to add aerials or other layers if they're offered.

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

Before you rely on the lines

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.
