About the official source
Sullivan County doesn't have its own viewer in our directory, so we point you to a statewide map: Tennessee Property Viewer (TN Comptroller). Zoom in on Sullivan County to see its parcels. Because a state agency compiles this layer from local data, check with the Sullivan County assessor or recorder before relying on a recent change. As of our October 2026 test, anyone could open it without signing in or paying.
