Completed in 1920, 300 Jay St rises 11 stories over Kings. Public records put it at 1 unit and 450,516 square feet of floor area, on land zoned C6-4. It is carried on the public rolls at a market value of $166M, and assessed for tax at $74.5M. In the 44 years its record reaches back, the lot has drawn 1,954 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 746 of its 1,954 records, fully 38%, fall under that one heading. Inspection (521) and violation (459) trail well behind. 220 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 2024.

On the environmental ledger, the building is benchmarked under Local Law 84, with a site energy-use intensity of 123.3 kBtu per square foot. Its operations answer for roughly 13,165 metric tons of CO2-equivalent a year.

Read together — 38% permit, 44 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$166M of Kings, written across 1,954 government filings.
