It is carried on the public rolls at a market value of $1.9M, and assessed for tax at $850K. In the 46 years its record reaches back, the lot has drawn 1,536 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward violation: 754 of its 1,536 records, fully 49%, fall under that one heading. Complaint (569) and inspection (52) trail well behind. 54 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 2015.

On the environmental ledger, the building posts an Energy Star score of 49, with a site energy-use intensity of 99.6 kBtu per square foot. Its operations answer for roughly 266 metric tons of CO2-equivalent a year.

Read together — 49% violation, 46 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.

$1.9M of New York, written across 1,536 government filings.
