Completed in 1962, 645 Water St rises 21 stories over New York. Public records put it at 211 units and 251,500 square feet of floor area, on land zoned R7-2. It is carried on the public rolls at a market value of $26.1M, and assessed for tax at $11.7M. In the 60 years its record reaches back, the lot has drawn 956 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward violation: 309 of its 956 records, fully 32%, fall under that one heading. Complaint (289) and permit (123) trail well behind. 75 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 2024.

On the environmental ledger, the building posts an Energy Star score of 78, with a site energy-use intensity of 42.0 kBtu per square foot. Its operations answer for roughly 540 metric tons of CO2-equivalent a year.

Read together — 32% violation, 60 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.

$26.1M of New York, written across 956 government filings.
