It is carried on the public rolls at a market value of $2.2M, and assessed for tax at $972K. In the 117 years its record reaches back, the lot has drawn 2,575 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,521 of its 2,575 records, fully 59%, fall under that one heading. Violation (858) and inspection (49) trail well behind. 46 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 2017.

On the environmental ledger, the building posts an Energy Star score of 70, with a site energy-use intensity of 82.4 kBtu per square foot. Its operations answer for roughly 266 metric tons of CO2-equivalent a year.

Read together — 59% complaint, 117 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.2M of Kings, written across 2,575 government filings.
