About This Property

East Cambridge 3-family on a scarce rectangular 6,333 sf lot with one street frontage on quiet one-way Union St and three sides at neighboring lots. Current C-1 dimensional table uses about a 10 ft front setback on the street side and about a 5 ft side setback, so a single-frontage lot can use more of the parcel than a lot with two street setbacks; buyer must verify all setbacks with the City.

Assessor: 18 rooms, 9 beds, 3.5 baths; living 4,355 sf (first floor 2,526 + finished upper 1,829); unfinished basement 2,526 sf; wood deck 363 sf; gross 7,244 sf. Renovated under permit BLDC-16364-2022; Luna plans attached. Current layout: 4 beds and 4 full baths per unit (12 / 12). Occupied income property; NFPA-13D sprinklers in each unit.
