Completed in 1964, 520 East 81ST St rises 14 stories over New York. Public records put it at 164 units and 94,886 square feet of floor area, on land zoned R8B. 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 1,560 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward mortgage: 344 of its 1,560 records, fully 22%, fall under that one heading. Release (341) and sale (304) trail well behind. 12 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 — 22% 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 1,560 government filings.
