Tucked off Monument Square on a gas-lit private way, this beautiful, 3+BR/2.5BA, single family home features 1,925+/- sf, an ideal open layout, sunny corner exposure and 1 car parking. The main level features an open concept “great” room with elegant living room with gas fireplace, with handsome white mantel, crown molding, and freshly sanded hardwood floors; an updated chef’s kitchen with white shaker cabinetry, quartz countertops, brand new stainless appliances, including gas range; and dining space with glass slider to a large private deck. Two generous bedrooms, each with corner exposure, and a well-appointed full bath with tub/shower make up the second level. A spacious and loft-like primary bedroom is located on the top level and features two sets of double closets and an updated full bath with glass enclosed shower with stone surround and white quartz-topped vanity. It also provides the perfect nook for a home office. The finished lower level offers a playroom/media room space, a half bath, storage, laundry center and direct egress to parking. This home is located close to everything Charlestown has to offer, including wonderful parks, shopping, restaurants and transportation, and the tucked away location gives it a suburban feel.
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 1,925 sq ft principal dwelling). Lot size: 900 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 MLS and other third-party data may be inaccurate or out of date.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.
