University Heights (North)-Fordham, The Bronx

University Heights (North)-Fordham's file describes a neighborhood whose building stock is overwhelmingly early: a median construction year of 1920, with 82% of recorded buildings predating 1940 and just 4% dating from the 1945-to-1975 postwar boom. Only 12% of the stock has gone up since 2000, keeping new construction a minor share of the total file even today. That timeline places most of the neighborhood's built environment well before the current zoning code existed, a detail that matters for any parcel-level look at what's actually allowed to be built today versus what's already standing.

Building classes run 33% walk-up apartments, 18% two-family homes, and 15% one-family homes, echoed by a land-use file where 33% of lots are logged for one- and two-family use, 29% for multifamily walk-up use, and 9% for mixed residential-and-commercial use. Median lot size runs 4,100 square feet, with the largest recorded lots reaching up to 14,464 square feet, room for a meaningfully wider range of parcel sizes than the median alone suggests.

Recorded development capacity is real here too: 70% of lots carry floor area below their district allowance, with a median residual FAR of 1. Floors run to a median of 3, and only 2% of recorded buildings rise above 6 stories. 80% of lots are logged as residential, carrying 17,579 housing units across the neighborhood's file. The mapped floodplain share stands at 1% of lots, and historic-district coverage is recorded at 0%.

That 1% mapped floodplain figure is worth reading precisely: it describes the current federal flood boundary crossing a small number of this neighborhood's lots, not a comprehensive statement about drainage or storm risk across the rest of the file. Combined with a median residual FAR of 1 and 70% of lots carrying some recorded headroom, the file describes a neighborhood where the physical building stock is old but the zoning allowance underneath it has not been fully used — two separate facts about the same set of parcels, not a single trend.

The neighborhood's mapped zoning runs mostly to apartment-house districts of varying density, bordering Bedford Park, Belmont, Fordham Heights, Kingsbridge Heights-Van Cortlandt Village, Kingsbridge-Marble Hill, and University Heights (South)-Morris Heights. Per-lot construction-year, building-class, and capacity records are available individually for each of these roughly 1,100 parcels rather than only as a neighborhood-wide average. That granularity matters most in a neighborhood this old, where a building's age on paper can differ block to block even within a single recorded median.
