Completed in 1971, 645 Madison Ave rises 22 stories over New York. Public records put it at 34 units and 164,615 square feet of floor area, on land zoned C5-3. It is carried on the public rolls at a market value of $110M, and assessed for tax at $49.7M. In the 58 years its record reaches back, the lot has drawn 1,345 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 768 of its 1,345 records, fully 57%, fall under that one heading. Inspection (190) and violation (127) trail well behind. 4 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 2019.

On the environmental ledger, the building posts an Energy Star score of 66, with a site energy-use intensity of 65.4 kBtu per square foot. Its operations answer for roughly 1,092 metric tons of CO2-equivalent a year.

Read together — 57% permit, 58 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.

$110M of New York, written across 1,345 government filings.
