Completed in 1928, 1820 Cortelyou Rd rises 6 stories over Kings. Public records put it at 42 units and 45,540 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $1.8M, and assessed for tax at $832K. In the 51 years its record reaches back, the lot has drawn 2,632 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,678 of its 2,632 records, fully 64%, fall under that one heading. Violation (782) and enforcement (52) trail well behind. 128 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 35, with a site energy-use intensity of 111.2 kBtu per square foot. Its operations answer for roughly 305 metric tons of CO2-equivalent a year.

Read together — 64% complaint, 51 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$1.8M of Kings, written across 2,632 government filings.
