It is carried on the public rolls at a market value of $8.8M, and assessed for tax at $4.0M. In the 98 years its record reaches back, the lot has drawn 1,244 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 606 of its 1,244 records, fully 49%, fall under that one heading. Violation (393) and permit (87) trail well behind. 24 violations stand open against it today.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2023.

On the environmental ledger, the building posts an Energy Star score of 100, with a site energy-use intensity of 23.2 kBtu per square foot. Its operations answer for roughly 232 metric tons of CO2-equivalent a year.

Read together — 49% complaint, 98 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$8.8M of Kings, written across 1,244 government filings.
