C1-8A Zoning District — New York City

Few designations in the file read as consistently residential as this one: 96% of these roughly 190 lots are coded residential use, and the file counts 4,717 homes across them. Walk-up apartment buildings lead the recorded building classes at 54%, well ahead of elevator apartment buildings at 17% and mixed residential-and-commercial buildings at 13% — a stock built overwhelmingly for housing rather than commerce, with little of the mixed-use pattern found elsewhere in the file. That combination of scale and consistency is uncommon; many comparably sized designations in this batch mix in at least some commercial or vacant-land presence, and this one's residential concentration reads as a defining trait rather than an incidental feature of a handful of lots.

The construction record here is genuinely old: a median year of 1893, with 88% of recorded buildings predating 1940. The postwar boom added little, at just 4% of the stock, and only 3% of buildings have gone up since 2000 — one of the quieter recent-construction figures in the file, consistent with a fabric that finished building out well over a century ago and has changed only modestly since. Little in the record suggests any real wave of rebuilding interrupted that long, slow finish.

A majority of these lots, 67%, also carry historic-district status — one of the higher recorded overlaps between this designation and landmark review, layering preservation rules on top of the zoning designation for most parcels here. Land use runs 69% mixed residential-and-commercial, 17% multi-family walk-up, and 9% multi-family elevator. Lots themselves run modest, with a median of 2,517 square feet and the 90th percentile reaching 8,137 square feet. That pairing — a majority historic overlap alongside almost no recorded flood exposure, described below — points to a designation shaped far more by preservation review than by any coastal or floodplain geography.

Buildings rise to a median of 5 stories, with 17% recorded above 6 floors, and none of these lots, 0%, sit inside the mapped federal flood zone. On the development side, 92% of lots record floor area below their allowance, with a median residual of 3.6 FAR — a wide recorded gap for a stock this old and this densely residential, describing capacity that has sat unused a long time on record rather than a recent change. Every one of these 190 lots has its own page carrying these same measures at the parcel level, and the floor-area and height limits that actually apply are cited in the tables above.
