Triple-Deckers, Brownstones and Narrow Stairwells
Around 15,000 triple-deckers were built across Boston and the surrounding cities between 1880 and 1930, and they are still a primary form of housing here. They are wood-frame, three units stacked, with narrow stairways and porches at both ends. Construction stopped by the 1930s after dozens of Massachusetts municipalities banned them, so what exists is what was built nearly a century ago.
That shapes the delivery more than the square footage does. Large sectional sofas, king mattresses and oversized wardrobes are the pieces most likely to stop at a landing. Measure the narrowest turn in your stairwell before move day and tell us the number. In the oldest parts of the city, street width is the other constraint, and a full-size truck may have to park further out with the carry done on foot.
