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 57 years its record reaches back, the lot has drawn 866 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward violation: 481 of its 866 records, fully 56%, fall under that one heading. Complaint (182) and enforcement (60) trail well behind. 49 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 2026.

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 — 56% violation, 57 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 866 government filings.
