The shortest bridge can take you the farthest away.At 50 Popponesset Island Road, across the signature one-lane bridge, something changes.The Pace… The Perspective… the connection to water and all that matters.Set on approximately .8 acre, this four-bedroom, 4,069-square-foot residence enjoys sweeping views across Popponesset Bay toward Nantucket Sound. From morning light on the bay to boats making their way toward the Sound and the changing colors of a Cape Cod sunset, water is the constant backdrop here.And it’s more than something to look at… A private dock puts Popponesset Bay, Nantucket Sound and the waters beyond at your door step. Step outside for a morning on the water, an afternoon cruise or an evening spent watching the sun settle across the Cape Cod landscape.The residence offers more than 4,000 square feet of living space, including two separate guest areas … an increasingly valuable feature for a Cape Cod property where family and friends inevitably want to visit.The house itself is ready for its next chapter. Its interiors provide an opportunity for a new owner to update and reimagine the home around today’s lifestyle and their own tastes. Please verify all information contained herein. The North side of the dock is leased through the end of November.

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 4,069 sq ft principal dwelling). Lot size: 34,950 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.
