It is carried on the public rolls at a market value of $28.5M, and assessed for tax at $12.8M. In the 103 years its record reaches back, the lot has drawn 1,233 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 613 of its 1,233 records, fully 50%, fall under that one heading. Inspection (170) and violation (169) trail well behind. 24 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 2018.

On the environmental ledger, the building posts an Energy Star score of 52, with a site energy-use intensity of 98.6 kBtu per square foot. Its operations answer for roughly 928 metric tons of CO2-equivalent a year.

Read together — 50% permit, 103 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.

$28.5M of New York, written across 1,233 government filings.
