In the 93 years its record reaches back, the lot has drawn 816 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 79, with a site energy-use intensity of 73.9 kBtu per square foot. Its operations answer for roughly 222 metric tons of CO2-equivalent a year.

Read together — 46% complaint, 93 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$3.2M of Kings, written across 816 government filings.
