It is carried on the public rolls at a market value of $113M, and assessed for tax at $50.8M. In the 60 years its record reaches back, the lot has drawn 1,163 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 627 of its 1,163 records, fully 54%, fall under that one heading. Enforcement (157) and violation (145) trail well behind. 6 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 2005.

On the environmental ledger, the building posts an Energy Star score of 91, with a site energy-use intensity of 73.0 kBtu per square foot. Its operations answer for roughly 1,952 metric tons of CO2-equivalent a year.

Read together — 54% permit, 60 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.

$113M of New York, written across 1,163 government filings.
