M1-4A/R9A Zoning District — New York City

Few designations profiled across these pages are this small. Citywide, only 6 tax lots carry it, which means every percentage that follows describes a handful of parcels rather than a broad pattern — read each figure as a count, not a trend. The city's tax-lot records also carry no reliable year-built, building-height, or land-use coverage for this designation, so no construction-era or height claim is possible here, and no land-use breakdown can be cited either. Where most designations in this file open with a construction date and a land-use split, this one cannot, and that absence is worth stating plainly rather than glossed over or estimated around.

What the records do carry is a building-class file leaning toward service and utility structures rather than housing: garages account for 50% of recorded classes, miscellaneous classifications add 33%, and utility-classed structures make up the remaining 17%. None of the three recorded classes is an ordinary housing type, consistent with a designation whose 6 lots sit outside the walk-up, rowhouse, or apartment patterns common elsewhere in this file. The designation's residential-share figure is itself unrecorded, though the file does count 7 housing units on record for it — a records detail worth noting on its own, since a lot can carry a unit count on file without the designation's residential share being recorded at all. That absence of an ordinary housing type is itself part of what this designation's file describes.

Every one of the 6 lots, 100%, records floor area below its allowance, and the typical gap is a wide one: a median residual of 7.3 FAR, among the deeper recorded gaps in this comparison set. Lots themselves run large — a median of 10,446 square feet, with the largest recorded parcel reaching 25,749 square feet — scale consistent with the garage and utility uses recorded above rather than with small residential parcels. What actually governs floor area and height on this designation is laid out, citations included, in the tables above — the record here is only what stands, not what is allowed.

Neither of the two overlay checks common to these pages turns up anything here: none of the 6 lots, 0%, sit inside the mapped federal flood zone, and none, 0%, carry historic-district status on record. That is a plain reading of the current maps for this small a set, not a broader claim about the surrounding area.

Set against the rest of this batch, this designation is the thinnest on recorded detail and among the smallest by lot count at once — a combination that makes each individual figure here carry more weight than it would on a larger designation.
