In the 54 years its record reaches back, the lot has drawn 1,351 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 871 of its 1,351 records, fully 64%, fall under that one heading. Violation (281) and enforcement (58) trail well behind. 27 violations stand open against it today.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2025.

On the environmental ledger, the building posts an Energy Star score of 99, with a site energy-use intensity of 41.1 kBtu per square foot. Its operations answer for roughly 105 metric tons of CO2-equivalent a year.

Read together — 64% complaint, 54 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$5.1M of New York, written across 1,351 government filings.
