Completed in 1963, 335 East 51ST St rises 14 stories over New York. Public records put it at 97 units and 49,892 square feet of floor area, on land zoned R8B. It is carried on the public rolls at a market value of $109K, and assessed for tax at $49.0K. In the 57 years its record reaches back, the lot has drawn 1,882 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward release: 381 of its 1,882 records, fully 20%, fall under that one heading. Assignment (352) and sale (338) trail well behind. 9 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 2007.

On the environmental ledger, the building posts an Energy Star score of 68, with a site energy-use intensity of 84.8 kBtu per square foot. Its operations answer for roughly 473 metric tons of CO2-equivalent a year.

Read together — 20% release, 57 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.

$109K of New York, written across 1,882 government filings.
