Belmont, The Bronx

The walk-up apartment building is Belmont's defining recorded form: 45% of building classes fall into that category, compared with 20% two-family homes and 6% mixed residential-and-commercial structures — the rest of the file splits across smaller shares. Land use tells the same story from a different angle, with 39% of lots logged for multifamily walk-up use, 24% for one- and two-family use, and 17% for mixed residential-and-commercial use. Across roughly 1,600 tax lots, that adds up to a neighborhood whose file reads overwhelmingly like the Bronx's classic mid-rise walk-up fabric rather than a rowhouse district or a tower district. Few lots on record carry any other building class in meaningful numbers, which is part of why the file reads as unusually uniform for a Bronx neighborhood of this size.

That building stock sits on a mostly prewar timeline — 78% of recorded buildings predate 1940, and the median construction year across the neighborhood is 1925. Only 2% of the stock dates from the 1945-to-1975 postwar boom, while 13% has gone up since 2000. Recorded capacity on the older stock still runs meaningful: 76% of lots carry floor area below their district allowance, with a median residual FAR of 1.2 — real headroom, even on a neighborhood this thoroughly built out already.

Median lot size runs 2,500 square feet, with the largest recorded lots reaching up to 7,648 square feet. Floors run to a median of 3, and just 2% of recorded buildings rise above 6 stories, keeping the skyline low despite the density of the walk-up stock. 82% of lots are logged as residential, carrying 14,374 housing units. Historic-district coverage and mapped floodplain share both stand at 0% for Belmont's lots — statements about the current regulatory boundaries, not claims about the neighborhood's age or its distance from water. That combination — low floor counts, high residential concentration, no recorded flood exposure — describes a neighborhood whose risk and scale profile is set almost entirely by its building age rather than its footprint on the map.

Belmont's mapped zoning groups mostly into apartment-house districts at varying densities, consistent with a neighborhood built up almost entirely with multifamily walk-up buildings. It borders Bedford Park, Fordham Heights, Mount Hope, Norwood, Tremont, University Heights (North)-Fordham, and West Farms — one of the more connected nodes among these Bronx files. Construction-year, building-class, and capacity data are available lot by lot for each of these roughly 1,600 parcels.
