About the official source
This map is published by or for Cobb 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
- Click the button above and wait for the Web AppBuilder viewer to load. Some counties show a terms screen first.
- Search by street address, owner or parcel ID if the search box offers those options.
- Click a lot on the map to read its attributes.
- Turn on aerial imagery from the basemap tool and use the layer list to add things like zoning or flood zones when they're published.
Many parcel sites expect owner names last name first. If a full name finds nothing, try just the surname.
