Lower East Side, Manhattan

Lower East Side's records run mixed-use in a way few Manhattan tax-lot files do. Land-use codes describe 53% of its roughly 920 lots as combined residential-and-commercial buildings, well ahead of the 14% recorded as plain multi-family walk-ups and the 10% recorded as commercial-and-office space. Building-class records tell a similar story: 42% of structures are classed as walk-up apartment buildings, another 11% as elevator apartment buildings, and a further 11% under a separate classification on record. Three-quarters of lots, 75%, carry a residential designation, and those lots hold 30,190 housing units between them, spread across a median lot size of 2,500 square feet.

None of the neighborhood's lots carry a mapped historic-district designation, a notable absence given how much of the building stock is old — the median lot's building dates to 1912, and 78% of the recorded stock predates 1940. Only 7% falls inside the postwar-boom years of 1945 to 1975, and 11% has gone up since 2000. Flood mapping reaches 2% of lots, a small but recorded share worth noting for anyone checking a specific parcel. Buildings run low: a median height of 5 stories, with only 15% rising above 6 floors. Development records show more room to add: 55% of lots carry recorded floor area below their district allowance, with a median residual of 0.3 in unused floor-area ratio.

Lot sizes vary widely against that 2,500-square-foot median — the upper end of the range reaches 17,400 square feet, meaning a tail of substantially larger holdings sits alongside the neighborhood's typical narrow parcel. That spread matters more here than in a neighborhood with a single uniform lot type, since a handful of larger assemblages can carry very different development math than the median rowhouse-scale lot next door. Neighboring tax-lot files pick up immediately in Chinatown-Two Bridges and the East Village, and across the river in Downtown Brooklyn-DUMBO-Boerum Hill, as well as Greenwich Village and SoHo-Little Italy-Hudson Square to the west.

The recorded zoning sits under low- and moderate-rise contextual and commercial-overlay districts, consistent with the 5-story median height and the thin slice of taller buildings on file. Those district rules are also what leaves the 55% headroom figure sitting where it does — plenty of built-out lots, but a citywide allowance most of the neighborhood's older buildings never fully used. For anyone researching a specific address here, per-lot detail — flood status, zoning district, recorded floor area against the district allowance — is available through PearlAudit's property records rather than only aggregated at the neighborhood level.
