In the 57 years its record reaches back, the lot has drawn 1,497 separate government filings — a paper trail nearly as tall as the building itself.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2013.

On the environmental ledger, the building posts an Energy Star score of 81, with a site energy-use intensity of 79.2 kBtu per square foot. Its operations answer for roughly 213 metric tons of CO2-equivalent a year.

Read together — 51% complaint, 57 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.5M of Kings, written across 1,497 government filings.
