Completed in 1938, 21 East 21ST St rises 6 stories over Kings. Public records put it at 41 units and 41,952 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $1.7M, and assessed for tax at $750K. In the 54 years its record reaches back, the lot has drawn 3,882 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 2,030 of its 3,882 records, fully 52%, fall under that one heading. Violation (1,634) and enforcement (53) trail well behind. 231 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 38, with a site energy-use intensity of 106.4 kBtu per square foot. Its operations answer for roughly 273 metric tons of CO2-equivalent a year.

Read together — 52% complaint, 54 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$1.7M of Kings, written across 3,882 government filings.
