C6-1G Zoning District — New York City

Among the designations profiled in this set, this one carries the oldest and the shortest recorded stock at once. The median construction year is 1910, and 87% of buildings predate 1940 — the highest prewar share of the group — while just 13% of the recorded stock rises above 6 floors, the lowest high-rise share among them. The 1945-to-1975 postwar boom barely touched these roughly 390 lots, adding only 3% of the stock, and construction since 2000 adds a further 7%, leaving the twentieth century's middle decades almost entirely absent from the file. Of every designation profiled in this set, none records a lower share of buildings dating to that postwar window, and none records a higher prewar share either.

The lots underneath are also the tightest in the group: a median of 2,250 square feet, with the largest lots on record reaching only 5,175 square feet. That is small-parcel, walk-up-corridor ground, and the recorded classes match it — store buildings and walk-up apartment buildings are tied at 26% each, with office buildings at 20%. Land use runs 55% mixed residential-and-commercial and 33% commercial and office, with public facilities and institutions recorded on 5% of lots. The remaining recorded building classes fall below the levels reported here individually, consistent with a fabric built up gradually rather than through a small number of large developments.

Residential use covers 56% of these lots, and the file counts 4,198 homes on record — a meaningful housing count layered onto what is, by building class, a heavily commercial-corridor mix. Height sits at a median of 5 floors, consistent with the low over-6-floor share noted above, and consistent too with a fabric old enough to predate the era of taller mid-rise construction seen elsewhere in this set. That combination — high residential coverage, an old and short recorded stock, and a corridor building mix — reads as one of the more internally consistent files in this set.

Development records show 32% of lots carrying floor area below their allowance, with a median residual of 0 — most of the built stock here already sits close to its recorded line, consistent with a fabric this old and this uniform. These lots sit outside both overlays this profile tracks: 0% inside the mapped Special Flood Hazard Area, 0% inside a designated historic district. Consistency of this kind, across age, height, and lot size all at once, is what a fabric built out uniformly and left largely alone tends to leave on the record. The specific figures for any one lot, governing allowance included, are set out with citations in the rules tables above.
