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.

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. Buyer must verify with Cambridge CDD and ISD current C-1 rules, including 4-story base height or up to 6 stories / 74 ft with inclusionary housing on lots of 5,000 sf or more, Lodging House use, basement treatment, occupancy, licensing, and parking.
