Property lines in Barnstable County, Massachusetts
A lot line on the Barnstable County GIS map near Brewster is a drawing based on deeds, not a measurement taken on site. Massachusetts is a metes-and-bounds state. Rural deeds in Barnstable County describe boundaries with bearings, distances and landmarks rather than a square grid, so parcel lines are often irregular.

Barnstable County at a glance: towns and land
Communities in the county include Barnstable, Bourne, Brewster, and Chatham. The map also labels unincorporated places, Buzzards Bay, Dennis Port, and East Dennis among them. Barnstable County covers about 394 square miles of land; its 2023 population estimate from the Census Bureau was 231,735. Development is heavy around Brewster, so lot-by-lot subdivision plats dominate the map near the population centers. Parcels touching the Cape Cod Bay and Buzzard's Bay tend to run long and narrow back from the water, a pattern you can see clearly on the Barnstable County map. Look for Cape Cod National Seashore and Mashpee National Wildlife Refuge on the map; the private tracts touching them are some of the most asked-about parcels in Barnstable County.
Hunting land and landowner permission in Barnstable County
Hunters working the country toward the Dukes County line can use the parcel map to put a name on every woodlot and field. Around Cape Cod National Seashore and Mashpee National Wildlife Refuge, private tracts can press right up against the public boundary, so check the lines before you walk in.

Where Barnstable County deeds and plats are kept
For land near Eastham, the parcel record is the index; the recorded deed is the source.

Finding vacant land and acreage in Barnstable County
Five steps for vacant land in Barnstable County:
- Start on the outskirts of Dennis, where empty lots are easy to spot between the houses on the aerial layer.
- Build a short list of open parcels around Bourne with owner names and acreage before you make any calls.
- Confirm legal access. In Barnstable County, as anywhere, a parcel with no road frontage depends on an easement.
- Assessed values lag the market, but comparing tracts near East Falmouth still shows which ones the county rates higher.
- Check the flood layer and ask about septic and permits; open land in Barnstable County isn't automatically buildable.
