It is carried on the public rolls at a market value of $3.7M, and assessed for tax at $1.7M. In the 52 years its record reaches back, the lot has drawn 3,479 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,808 of its 3,479 records, fully 52%, fall under that one heading. Violation (1,494) and enforcement (39) trail well behind. 443 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 2026.

On the environmental ledger, the building posts an Energy Star score of 20, with a site energy-use intensity of 114.8 kBtu per square foot. Its operations answer for roughly 497 metric tons of CO2-equivalent a year.

Read together — 52% complaint, 52 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$3.7M of Kings, written across 3,479 government filings.
