About the official source
The link goes to a statewide map (MassGIS Interactive Property Map). It shows parcels for Norfolk County along with the rest of Massachusetts. Statewide parcel layers are usually stitched together from county files, so the newest splits or sales may show up on the county's own records first. When we tested the link in October 2026 it opened with no login and no fee.

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.
