It is carried on the public rolls at a market value of $664K, and assessed for tax at $299K. In the 62 years its record reaches back, the lot has drawn 1,622 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward mortgage: 342 of its 1,622 records, fully 21%, fall under that one heading. Release (340) and sale (297) trail well behind. 8 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 2003.

On the environmental ledger, the building posts an Energy Star score of 66, with a site energy-use intensity of 107.5 kBtu per square foot. Its operations answer for roughly 700 metric tons of CO2-equivalent a year.

Read together — 21% mortgage, 62 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.

$664K of New York, written across 1,622 government filings.
