Where the parcel data comes from
The link goes to a statewide map (Maine GeoLibrary Parcel Viewer). It shows parcels for Penobscot County along with the rest of Maine. Because a state agency compiles this layer from local data, check with the Penobscot 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.
Searching for a parcel, step by step
- Open Maine GeoLibrary Parcel Viewer in a new tab and zoom to Penobscot County (around Bangor).
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.
- Confirm anything important with the county assessor, since the statewide layer is a compiled copy.
Rural addresses don't always geocode well. When that happens, zoom in by hand and click the parcel, or search by owner name.
