Completed in 1909, 20 Jay St rises 11 stories over Kings. Public records put it at 240 units and 500,000 square feet of floor area, on land zoned M1-4/R8A. It is carried on the public rolls at a market value of $76.7M, and assessed for tax at $34.5M. In the 75 years its record reaches back, the lot has drawn 1,020 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 332 of its 1,020 records, fully 33%, fall under that one heading. Violation (182) and enforcement (170) trail well behind. 5 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 2007.

On the environmental ledger, the building posts an Energy Star score of 97, with a site energy-use intensity of 28.8 kBtu per square foot. Its operations answer for roughly 1,187 metric tons of CO2-equivalent a year.

Read together — 33% permit, 75 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$76.7M of Kings, written across 1,020 government filings.
