Avison Young is pleased to offer for sale 50B Park Street, a 20,500 SF industrial flex building ideally located in Dorchester, Massachusetts. Originally constructed as a manufacturing and warehousing facility with long-term adaptability in mind, the property is currently configured as office space and is fully vacant and move-in ready following the recent departure of a long-term government tenant in July 2025. Easily convertible to its original uses as flex or industrial, 50B Park Street is in excellent overall condition and provides the rare opportunity for a new tenant or owner-user to establish a full building identity in Boston’s supply constrained urban industrial market.
