Rarely available, and well loved through generations, this handsome, 4+BR/2BA, brick two-family home on coveted Auburn Street offers nearly 2,600 square feet of living space and an additional 917sf of unfinished basement space, providing an extraordinary opportunity for an investor, contractor, or end-user to build equity or seamlessly convert to a single-family residence. Set on a picturesque, tree-lined street, the building features a grand entry foyer, tall ceiling height throughout, large windows that flood the rooms with natural light, and a blend of rich original oak and pine floors. The oversized first-floor, 1BR/1BA apartment offers a spacious 900+sf layout, featuring formal living and dining room parlors with pine floors, a full bath with tub, and an inviting kitchen that opens onto a private deck, which leads to a large, fenced in yard waiting to be brought back to a lush sanctuary. The “owner’s” unit is an impressive 3+BR/1BA, 1,600sf upper duplex with a spectacular front living room parlor with white marble mantel, ornate ceiling medallion and crown molding. A formal dining room parlor flows to the updated kitchen featuring stainless appliances and quartz countertops. A full bath with tub and a separate laundry room/pantry complete this level. The upper level offers 3 bedrooms, plus study, bathed in light from front and back windows and a skylight. This home is close to all Charlestown has to offer with great parks, local dining, shopping, and transport to downtown Boston.
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 2,590 sq ft principal dwelling). Lot size: 1,833 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.
Estimates — not financial advice
These figures are illustrative estimates for informational purposes only — not an appraisal, valuation, or guarantee of rent, income, or returns, and not financial, tax, or investment advice. Rent is either the figure reported on the MLS listing — in-place rent that may differ from market and is not verified against the actual leases — or, where the listing reports none, an estimate from HUD Small Area Fair Market Rents, a government benchmark that may differ from actual market rent. Each figure is labelled with its source. Cap rate, NOI, and returns depend on the assumptions shown, which you can change. MLS and other third-party data may be inaccurate or out of date. Verify all figures independently and consult your own financial, tax, and legal advisors before making any investment decision.
