It is carried on the public rolls at a market value of $87.1M, and assessed for tax at $39.2M. In the 97 years its record reaches back, the lot has drawn 1,363 separate government filings — a paper trail nearly as tall as the building itself.

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 40, with a site energy-use intensity of 78.3 kBtu per square foot. Its operations answer for roughly 122 metric tons of CO2-equivalent a year.

Read together — 34% permit, 97 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.

$87.1M of New York, written across 1,363 government filings.
