Completed in 1964, 91 Boerum St rises 22 stories over Kings. Public records put it at 387 units and 447,000 square feet of floor area, on land zoned R6. It is carried on the public rolls at a market value of $60.2M, and assessed for tax at $27.1M. In the 56 years its record reaches back, the lot has drawn 931 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward violation: 477 of its 931 records, fully 51%, fall under that one heading. Complaint (173) and inspection (123) trail well behind. 53 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 2018.

On the environmental ledger, the building posts an Energy Star score of 100, with a site energy-use intensity of 17.6 kBtu per square foot. Its operations answer for roughly 878 metric tons of CO2-equivalent a year.

Read together — 51% violation, 56 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$60.2M of Kings, written across 931 government filings.
