It is carried on the public rolls at a market value of $183M, and assessed for tax at $82.6M. In the 58 years its record reaches back, the lot has drawn 1,747 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 1,057 of its 1,747 records, fully 61%, fall under that one heading. Inspection (248) and violation (165) 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 2024.

On the environmental ledger, the building posts an Energy Star score of 91, with a site energy-use intensity of 63.3 kBtu per square foot. Its operations answer for roughly 2,567 metric tons of CO2-equivalent a year.

Read together — 61% permit, 58 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.

$183M of New York, written across 1,747 government filings.
