The drone nearly missed it. Tucked so deeply beneath a mature canopy that it barely registers from above, 48 Black Flats Road reveals itself only after a long, private journey down a winding dirt drive. Then the trees part and nearly two acres open around you. From that same aerial vantage, Cape Cod Bay glimmers beyond the marsh, with Mayflower and Bay View Beaches stretching across the frame. The water is close. The world is not. Set approximately 956 feet back from Black Flats Road, this substantial 1972 Garrison Colonial offers approximately 2,100 square feet with four bedrooms, generous room sizes, a traditional floor plan, fireplace, mudroom and laundry. The house is largely original and ready for significant updating—an opportunity to take a substantial home in an exceptional setting and make it your own. But what may be hardest to duplicate is what surrounds it. The property consists of two parcels creating nearly two acres, with the long driveway corridor providing a natural buffer from the road. There is a large clearing around the house, plenty of parking and space to imagine gardens, outdoor entertaining and other thoughtful improvements, subject to required approvals.

ADU Potential

Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 2,100 sq ft principal dwelling). Lot size: 74,488 sq ft.

Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
