Set on an exceptional 8,373 square foot lot just moments from Wollaston Beach and the North Quincy T, this meticulously maintained two-family has been cherished and occupied by the same family for more than 60 years—a rarity in every sense. Offering more than 3,000 square feet of living space with 5 bedrooms across two expansive residences, the home provides remarkable flexibility for owner-occupants, investors, or multi-generational living. The first-floor unit features soaring ceilings and an updated full bath, while the upper bi-level residence offers spacious living, a newer kitchen, 3+ bedrooms, sitting room, and an enclosed rear porch. Downstairs, a full basement with high ceilings and an existing bath presents potential for future expansion. Outside, the oversized lot offers room to garden, play, entertain, or explore what's next. A detached two-car garage adds valuable utility today while also inviting buyers to consider the potential for a future accessory dwelling unit (ADU), subject to local zoning and permitting. Decades of thoughtful upkeep are evident throughout, including vinyl siding, replacement windows, an asphalt shingle roof, and new front and rear steps.A+ Location. Walk to the beach. Walk to the T. Reach downtown Boston in minutes. Remarkably, this property is not located in a flood zone, allowing you to enjoy the coastal lifestyle without the added cost of flood insurance. Opportunities like this rarely come to market. A lovingly maintained property on a lot of this size in one of Quincy's most desired neighborhoods. Whether you're building wealth, accommodating extended family, or looking for room to grow, 15 Colby Road is ready for its next chapter.
