7 guides on the peninsula Boston started from and the fill that grew off it. The colonial street plan downtown was never straightened. Beacon Hill's Federal brick has been under architectural review since 1955, the oldest such commission in Massachusetts, and the North End is the oldest continuously inhabited neighborhood in the city. The ground gets newer as you move outward: the West End was rebuilt after a 1958 clearance that took 46 acres and displaced thousands, and the Seaport was built almost entirely after 2000.
Two things separate this part from the rest of Boston. The first is that almost nothing here is a house. The stock is apartments, condominiums and converted rowhouses, so the questions are the association's reserve, the age of the building and what the deed restricts, rather than the roof and the lot. The second is the water. The Seaport and the South Boston waterfront sit on filled harbor at the front of the City's own climate planning, and the Harborwalk running through them is the line the flood modeling is drawn against. Ask for the building's flood zone, and ask what its garage did in the last storm, before anything else.
