Completed in 1887, 100 West 21 St rises 7 stories over New York. Public records put it at 106,279 square feet of floor area, on land zoned C6-2A. It is carried on the public rolls at a market value of $12.2M, and assessed for tax at $5.5M. In the 40 years its record reaches back, the lot has drawn 1,368 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 500 of its 1,368 records, fully 37%, fall under that one heading. Release (191) and enforcement (177) trail well behind. 3 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 7, with a site energy-use intensity of 73.0 kBtu per square foot. Its operations answer for roughly 827 metric tons of CO2-equivalent a year.

Read together — 37% permit, 40 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.

$12.2M of New York, written across 1,368 government filings.
