It is carried on the public rolls at a market value of $65.3M, and assessed for tax at $29.4M. In the 58 years its record reaches back, the lot has drawn 854 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 410 of its 854 records, fully 48%, fall under that one heading. Inspection (148) and enforcement (115) trail well behind. 7 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 2017.

On the environmental ledger, the building posts an Energy Star score of 92, with a site energy-use intensity of 47.4 kBtu per square foot. Its operations answer for roughly 498 metric tons of CO2-equivalent a year.

Read together — 48% 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.

$65.3M of New York, written across 854 government filings.
