About this home
258-270 K street is an exceptionally rare corner lot development opportunity with multiple curb cuts in the heart of South Boston. 258-266 K street is formally the site of the beloved Joseph's Bakery and consists of 3700 usable sf + basement on a 5368 sf lot. 268-270 K street, the adjacent building is a 3228 sf well maintained 2-family on a 6603 sf lot. Additionally, this parcel has 10 gated parking spaces, an extreme rarity in Southie! The sale of the 2 parcels would give the buyer a combined 11,971 sf lot. Located in the South Boston Neighborhood MFR zoning district, there is a wide array of allowed & conditional uses for redevelopment. With approval, highest & best use is expected to be a fully residential conversion or a mixed use retail/residential conversion. The multifamily residential subdistrict dimensional regulations including FAR, frontage, building height, etc. can be found in article 68 table D on the Boston planning and development agency website.
