Completed in 2002, 1721 1 Ave rises 31 stories over New York. Public records put it at 175,111 square feet of floor area, on land zoned C2-8. It is carried on the public rolls at a market value of $10.6M, and assessed for tax at $4.8M. In the 45 years its record reaches back, the lot has drawn 851 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward sale: 222 of its 851 records, fully 26%, fall under that one heading. Release (189) and mortgage (168) 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 2017.

On the environmental ledger, the building posts an Energy Star score of 41, with a site energy-use intensity of 92.0 kBtu per square foot. Its operations answer for roughly 1,428 metric tons of CO2-equivalent a year.

Read together — 26% sale, 45 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.

$10.6M of New York, written across 851 government filings.
