Completed in 1909, 1 West 23 St rises 15 stories over New York. Public records put it at 34 units and 704,950 square feet of floor area, on land zoned C5-2. It is carried on the public rolls at a market value of $440M, and assessed for tax at $198M. In the 59 years its record reaches back, the lot has drawn 3,192 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 1,854 of its 3,192 records, fully 58%, fall under that one heading. Enforcement (559) and violation (264) trail well behind. 1 violation stands 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 2012.

On the environmental ledger, the building posts an Energy Star score of 86, with a site energy-use intensity of 67.1 kBtu per square foot. Its operations answer for roughly 4,861 metric tons of CO2-equivalent a year.

Read together — 58% permit, 59 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.

$440M of New York, written across 3,192 government filings.
