Harlem (North), Manhattan

Harlem (North) carries the lowest share of unused development capacity of any neighborhood profiled in this set of pages: 65% of lots have floor area still available under current district limits, with a median residual of 1.2 FAR points — meaning more of this neighborhood's built floor area already approaches its allowed limit than in any other file covered here. That figure stands in contrast to several neighboring files, where a larger share of recorded floor area still sits below what current district rules would allow.

By scale, Harlem (North) is the largest neighborhood among the nearby Harlem-named files: roughly 2,400 tax lots, carrying 41,090 housing units in total, with 84% of lots coded residential. Building-class records show walk-up apartment buildings as the dominant type at 54% of lots, with two-family classifications at 10% and elevator-apartment buildings at 7%. Land-use coding lines up, with 45% of lots coded multi-family walk-up, 18% mixed residential-and-commercial, and 15% one- and two-family, a pattern broadly similar to neighboring Harlem (South) but recorded at a larger scale. That scale, combined with the neighborhood's walk-up-dominated building stock, describes one of the larger and more uniformly coded residential files among the Harlem-named neighborhoods covered here.

Age records show 86% of buildings predating 1940, a median construction year of 1910, and 8% of the stock dated since 2000 — a recent-construction share on the higher end among the neighborhoods covered here. Just 4% of buildings fall inside the 1945-to-1975 postwar boom. A historic district designation covers 23% of lots. Even with comparatively low unused development capacity, the age record shows a building stock built predominantly before the current zoning code took shape, with only a modest recent-construction addition layered on top.

Height records show a median building of 4 stories, with only 5% rising above 6 stories — a low-rise profile despite the neighborhood's overall scale and its comparatively tight recorded development headroom. Lot sizes run to a median of 2,298 square feet, with the largest recorded lots reaching 9,983 square feet. Flood mapping places just 1% of lots inside the federally mapped floodplain, a small figure describing the current regulatory map rather than a claim about water history at any address. Between its scale, its walk-up-dominated building stock, and its comparatively low recorded development headroom, Harlem (North)'s file describes a neighborhood whose built floor area already tracks closer to its allowed limits than most of its neighbors.
