Completed in 2007, 447 West 18 St rises 12 stories over New York. Public records put it at 46 units and 70,730 square feet of floor area, on land zoned R8A. It is carried on the public rolls at a market value of $1.4M, and assessed for tax at $614K. In the 43 years its record reaches back, the lot has drawn 999 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 188 of its 999 records, fully 19%, fall under that one heading. Mortgage (166) and release (151) 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 2009.

On the environmental ledger, the building posts an Energy Star score of 45, with a site energy-use intensity of 50.0 kBtu per square foot. Its operations answer for roughly 351 metric tons of CO2-equivalent a year.

Read together — 19% permit, 43 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.

$1.4M of New York, written across 999 government filings.
