Longwood, The Bronx

Longwood's most distinctive line item is preservation: 9% of its roughly 1,600 tax lots sit inside a designated historic district, a share the adjoining files mostly lack. Designation is a recorded constraint with practical meaning — within the district boundaries, exterior work passes through preservation review, which is why the fact belongs in a property file at all. The age columns explain what drew the designation: 53% of buildings predate 1940, and the median build year is 1930, placing the neighborhood's signature masonry rowhouses and walk-ups squarely in the early decades of the borough's build-out.

The class ledger is dominated by small multi-family buildings. Walk-up apartment buildings account for 36% of classes and two-family homes for 24%, with one-family homes at 9%. By land use the order flips at the top: one- and two-family buildings edge out walk-ups, 33% of lots to 32%, and mixed residential-commercial buildings take another 10%. It is an emphatically residential file — 81% of lots — holding 17,066 housing units at a median height of 3 stories, with only 3% of buildings rising past 6 floors. Lots are uniform and small, at a median of 2,500 square feet, though one in ten reaches 11,400 or more.

The mid-century barely registers: just 1% of Longwood's stock dates from the boom years between 1945 and 1975, and new construction since 2000 accounts for 12% — present, but not remaking the place. The zoning file, meanwhile, shows substantial slack. Some 82% of lots hold recorded floor area short of the district allowance, with a median residual floor-area ratio of 2.2 — wide margins for a fabric this low, though the figure measures paper capacity lot by lot and says nothing about intent.

Flood risk is a map question here, and the map answer is zero: 0% of lots fall inside the federally mapped floodplain. That describes FEMA's maps as currently drawn, not a promise about what water will ever do. Longwood's file sits among those of Hunts Point, Melrose, Morrisania, Crotona Park East, and Mott Haven-Port Morris — a ring in which it stands out for pairing a protected core with broad unused allowance.
