The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2020.

On the environmental ledger, the building posts an Energy Star score of 36, with a site energy-use intensity of 68.3 kBtu per square foot. Its operations answer for roughly 2,243 metric tons of CO2-equivalent a year.

Read together — 26% complaint, 36 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$12.8M of Kings, written across 1,325 government filings.
