It is carried on the public rolls at a market value of $460K, and assessed for tax at $207K. In the 40 years its record reaches back, the lot has drawn 182 separate government filings.

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 is benchmarked under Local Law 84, with a site energy-use intensity of 38.0 kBtu per square foot. Its operations answer for roughly 93 metric tons of CO2-equivalent a year.

Read together — 37% violation, 40 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$460K of Kings, written across 182 government filings.
