In the 100 years its record reaches back, the lot has drawn 1,111 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward inspection: 642 of its 1,111 records, fully 58%, fall under that one heading. Permit (249) and violation (79) 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 2019.

On the environmental ledger, the building posts an Energy Star score of 81, with a site energy-use intensity of 62.1 kBtu per square foot. Its operations answer for roughly 377 metric tons of CO2-equivalent a year.

Read together — 58% inspection, 100 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.

$20.4M of New York, written across 1,111 government filings.
