It is carried on the public rolls at a market value of $231M, and assessed for tax at $104M. In the 47 years its record reaches back, the lot has drawn 6,118 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 3,724 of its 6,118 records, fully 61%, fall under that one heading. Inspection (1,667) and violation (352) trail well behind. 3 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 78, with a site energy-use intensity of 61.0 kBtu per square foot. Its operations answer for roughly 7,677 metric tons of CO2-equivalent a year.

Read together — 61% permit, 47 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.

$231M of New York, written across 6,118 government filings.
