M1-4A/R7-2 Zoning District — New York City

Just 2 tax lots citywide carry this designation, and unlike most small designations in this file, these two do not split down the middle — they match. Every recorded building on them, 100%, predates 1940, and the median construction year is 1913, the oldest median in this batch of designations. None of the recorded stock, 0%, dates from the 1945-1975 postwar boom or from 2000 onward — a stock frozen, on record, well before the middle of the twentieth century, with nothing added or replaced in the decades since, and with none of the split-era pattern that shows up on so many other small designations in this file.

The land use and building-class records are each entirely uniform too: a single recorded land-use category accounts for 100% of these lots, and a single recorded building class accounts for 100% of the stock. That kind of total concentration — one era, one land use, one building class — is uncommon among the designations profiled in this file, most of which mix at least two or three recorded categories across age, use, and building type, even when their footprint is just as small as this one's.

Lot size tells the same story: both the median and the 90th-percentile figure land on exactly 50,537 square feet, meaning the two lots carrying this designation are recorded at the same size rather than spanning a range, unlike most percentile pairs in this file, which typically show a meaningful gap between a median and a 90th-percentile figure. None of these lots, 0%, are coded residential, though the file still counts 3 recorded units across them. Neither lot sits inside the mapped federal flood zone, 0%, and neither carries historic-district status, 0% — an entirely uniform record across every family of statistics the file tracks for this designation.

The development ledger shows full recorded headroom: 100% of lots record floor area below their allowance, at a median gap of 1.9 FAR. Paired with the uniform age, land use, building class, and lot size above, this designation's file is about as internally consistent as any two-lot record in this batch can be. For a designation this small and this uniform, per-lot records still carry the specifics for each of the 2 parcels individually, even where every designation-wide figure above happens to describe both of them equally; the floor-area and height rules that actually govern this designation are cited, with sources, in the tables above.
