The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2005.

On the environmental ledger, the building posts an Energy Star score of 74, with a site energy-use intensity of 77.9 kBtu per square foot. Its operations answer for roughly 439 metric tons of CO2-equivalent a year.

Read together — 67% complaint, 100 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

67% of every record here performs the same act: complaint.
