Completed in 1981, 523 East 80 St rises 12 stories over New York. Public records put it at 130,725 square feet of floor area, on land zoned R8B. It is carried on the public rolls at a market value of $1.8M, and assessed for tax at $789K. In the 125 years its record reaches back, the lot has drawn 845 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward mortgage: 278 of its 845 records, fully 33%, fall under that one heading. Sale (189) and release (174) trail well behind. No 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 1983.

On the environmental ledger, the building posts an Energy Star score of 92, with a site energy-use intensity of 37.9 kBtu per square foot. Its operations answer for roughly 494 metric tons of CO2-equivalent a year.

Read together — 33% mortgage, 125 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.

$1.8M of New York, written across 845 government filings.
