It is carried on the public rolls at a market value of $2.1M, and assessed for tax at $933K. In the 80 years its record reaches back, the lot has drawn 1,260 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 581 of its 1,260 records, fully 46%, fall under that one heading. Violation (436) and inspection (116) trail well behind. 51 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 2018.

On the environmental ledger, the building posts an Energy Star score of 42, with a site energy-use intensity of 99.1 kBtu per square foot. Its operations answer for roughly 269 metric tons of CO2-equivalent a year.

Read together — 46% complaint, 80 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.

$2.1M of New York, written across 1,260 government filings.
