The five-story building at 402 Washington Avenue is about to move to the head of the class. After many years as a Class B Multiple Dwelling (which includes several kinds of “transient” housing), the beautiful brick structure is betting converted into five Class A, or permanent, apartments. (For more details on the difference between Class A and Class B, click here.) No word on whether it’ll be condos or rentals, but we’d bet the latter. GMAP P*Shark DOB
