Some places make the rest of the world feel very far away. Tucked along the shoreline of Mattapoisett’s private Crescent Beach community, 4 Union Ave is one of them, a fully renovated oceanfront retreat where sweeping water views, salty air, and the sound of the waves become part of everyday life. Perched above the flood zone and offered fully furnished, this coastal escape has been thoughtfully transformed from top to bottom. The new kitchen pairs warm oak cabinetry with quartz countertops, KitchenAid appliances, a porcelain farmhouse sink, custom hood, and center island. New hardwood floors run throughout, alongside a beautifully renovated bath with radiant heated floors. A new roof, new sliders, new heating and cooling system, updated electrical and plumbing, and brand-new decking complete the extensive renovation. Upstairs, the loft offers flexible space for an office or second living area, along with custom built-in beds perfect for children or overnight guests. Outside, step onto the new deck and take in truly remarkable ocean views. Peaceful, private, and effortlessly timeless, this is the kind of place that feels less like a house and more like an escape you never want to leave.

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: 630 sq ft (the lesser of 900 sq ft or half the 1,260 sq ft principal dwelling). Lot size: 5,000 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.
