It is carried on the public rolls at a market value of $4.4M, and assessed for tax at $2.0M. In the 65 years its record reaches back, the lot has drawn 2,987 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,578 of its 2,987 records, fully 53%, fall under that one heading. Violation (1,204) and inspection (78) trail well behind. 170 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 2015.

On the environmental ledger, the building posts an Energy Star score of 11, with a site energy-use intensity of 137.0 kBtu per square foot. Its operations answer for roughly 771 metric tons of CO2-equivalent a year.

Read together — 53% complaint, 65 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$4.4M of Kings, written across 2,987 government filings.
