Completed in 1925, 100 West 56 St rises 18 stories over New York. Public records put it at 167 units and 243,671 square feet of floor area, on land zoned C6-6. It is carried on the public rolls at a market value of $71.4M, and assessed for tax at $32.1M. In the 58 years its record reaches back, the lot has drawn 950 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 286 of its 950 records, fully 30%, fall under that one heading. Enforcement (202) and inspection (161) trail well behind. 5 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 2026.

On the environmental ledger, the building posts an Energy Star score of 7, with a site energy-use intensity of 91.0 kBtu per square foot. Its operations answer for roughly 1,581 metric tons of CO2-equivalent a year.

Read together — 30% 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.

$71.4M of New York, written across 950 government filings.
