It is carried on the public rolls at a market value of $10.7M, and assessed for tax at $4.8M. In the 80 years its record reaches back, the lot has drawn 218 separate government filings.

The documentary life of the address leans hard toward permit: 61 of its 218 records, fully 28%, fall under that one heading. Violation (59) and enforcement (46) trail well behind. 3 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 2013.

On the environmental ledger, the building posts an Energy Star score of 10, with a site energy-use intensity of 104.9 kBtu per square foot. Its operations answer for roughly 1,421 metric tons of CO2-equivalent a year.

Read together — 28% permit, 80 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$10.7M of Kings, written across 218 government filings.
