Where the parcel data comes from
The link goes to a statewide map (Maine GeoLibrary Parcel Viewer). It shows parcels for Sagadahoc County along with the rest of Maine. A statewide layer can trail the county's own books by weeks or months, so treat it as a fast first look rather than the final word. When we tested the link in October 2026 it opened with no login and no fee.
Finding a property on this statewide map
- Open Maine GeoLibrary Parcel Viewer in a new tab and zoom to Sagadahoc County (around Bath).
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.

Before you rely on the lines
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.
