For over 150 years, 12 Auburn Street has been part of Charlestown’s neighborhood foundation. Set on a cozy residential street moments from Main Street and the historic waterfront, this historic brick brownstone offers a rare chance to own a piece of architectural legacy while shaping its next chapter. Spanning four levels and 3,350+ square feet, the home offers scale and structure emblematic of its era. Currently configured as a multi-family, it includes a generous garden-level residence with private front and rear access, while the upper levels live comfortably as a single-family. The property features three bedrooms, three full and one half renovated bathrooms, a spacious entertainment room, an updated kitchen, and a private backyard deck and patio. Also included are one deeded garage parking space approximately 600 feet away and two additional transferable off-street spaces. Original character, enduring construction, and timeless appeal make this a rare Charlestown opportunity.
