It is carried on the public rolls at a market value of $4.2M, and assessed for tax at $1.9M. In the 34 years its record reaches back, the lot has drawn 951 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 2026.

On the environmental ledger, the building posts an Energy Star score of 12, with a site energy-use intensity of 94.7 kBtu per square foot. Its operations answer for roughly 539 metric tons of CO2-equivalent a year.

Read together — 62% complaint, 34 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$4.2M of Kings, written across 951 government filings.
