It is carried on the public rolls at a market value of $15.2M, and assessed for tax at $6.8M. In the 45 years its record reaches back, the lot has drawn 212 separate government filings.

The documentary life of the address leans hard toward permit: 80 of its 212 records, fully 38%, fall under that one heading. Complaint (49) and enforcement (32) trail well behind. No 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 2022.

On the environmental ledger, the building posts an Energy Star score of 98, with a site energy-use intensity of 20.5 kBtu per square foot. Its operations answer for roughly 190 metric tons of CO2-equivalent a year.

Read together — 38% permit, 45 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$15.2M of Kings, written across 212 government filings.
