Completed in 1892, 21 Astor Pl rises 11 stories over New York. Public records put it at 54 units and 107,106 square feet of floor area, on land zoned C6-2. It is carried on the public rolls at a market value of $281K, and assessed for tax at $127K. In the 1827 years its record reaches back, the lot has drawn 1,803 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward release: 494 of its 1,803 records, fully 27%, fall under that one heading. Permit (335) and mortgage (265) trail well behind. 4 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 2004.

On the environmental ledger, the building posts an Energy Star score of 48, with a site energy-use intensity of 45.5 kBtu per square foot. Its operations answer for roughly 601 metric tons of CO2-equivalent a year.

Read together — 27% release, 1827 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.

$281K of New York, written across 1,803 government filings.
