Bushwick (West), Brooklyn

Two numbers organize everything in the western Bushwick file: 84% of tax lots hold recorded floor area below what their zoning districts allow — more than four lots in five — and the median gap is 0.7 FAR. That headroom sits over a stock built low and early: a median height of 3 stories, only 1% of buildings above 6 floors, and a median year built of 1931. Whatever reasons individual owners have for leaving capacity unused, the capacity itself is not hypothetical; it is recorded, lot by lot, across roughly 4,700 parcels. Few files pair a fabric this settled with a ledger this open.

The building mix is the walk-up pattern at nearly its purest. Walk-up apartment buildings account for 48% of recorded classes, matching the 48% of land in multi-family walk-up use, with two-family homes at 20% and mixed residential-commercial buildings at 12%. One- and two-family parcels cover another 23% of the land and mixed-use parcels 16%. The neighborhood is 88% residential by lot count and holds 25,908 housing units. Commercial corridors and pockets of manufacturing zoning thread through the map, which is part of why headroom varies street to street even when the aggregate runs this high — the building type and the parcel fabric grew up together here, and the records show it.

The age story is prewar with a late start. 76% of buildings predate 1940, but the median year of 1931 runs a generation younger than the brownstone districts to the west — this fabric rose in the booms just before the war rather than at the turn of the century. The interval between 1945 and 1975 added only 2% of the stock, while 16% dates from 2000 or later. The lots underneath are compact and regular, at a median of 2,500 square feet with a ninetieth percentile of 3,400.

Neither of the usual regulatory overlays reaches far here: 0% of lots sit inside a designated historic district, and 0% fall within the federally mapped special flood hazard area — the latter a fact about FEMA's regulatory boundaries, which do not speak to stormwater or drainage. Western Bushwick borders Bedford-Stuyvesant (East), Bushwick (East), East Williamsburg, South Williamsburg, and Ridgewood across the Queens line. The per-lot records — floor area, allowance, year built, class — are where the 84% figure stops being an average and becomes a fact about a specific address.
