Completed in 1989, 300 West 66 St rises 7 stories over New York. Public records put it at 474,496 square feet of floor area, on land zoned C4-2F. It is carried on the public rolls at a market value of $77.0M, and assessed for tax at $34.7M. In the 46 years its record reaches back, the lot has drawn 913 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 534 of its 913 records, fully 58%, fall under that one heading. Violation (157) and enforcement (68) 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 2021.

On the environmental ledger, the building posts an Energy Star score of 97, with a site energy-use intensity of 26.1 kBtu per square foot. Its operations answer for roughly 940 metric tons of CO2-equivalent a year.

Read together — 58% permit, 46 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.

$77.0M of New York, written across 913 government filings.
