It is carried on the public rolls at a market value of $2.1M, and assessed for tax at $927K. In the 99 years its record reaches back, the lot has drawn 1,260 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 2004.

On the environmental ledger, the building posts an Energy Star score of 88, with a site energy-use intensity of 62.0 kBtu per square foot. Its operations answer for roughly 237 metric tons of CO2-equivalent a year.

Read together — 79% complaint, 99 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

79% of every record here performs the same act: complaint.
