Completed in 1938, 80 Clarkson Ave rises 6 stories over Kings. Public records put it at 83 units and 97,137 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $3.6M, and assessed for tax at $1.6M. In the 61 years its record reaches back, the lot has drawn 6,298 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 3,858 of its 6,298 records, fully 61%, fall under that one heading. Violation (2,172) and enforcement (62) trail well behind. 175 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 2025.

On the environmental ledger, the building posts an Energy Star score of 89, with a site energy-use intensity of 56.0 kBtu per square foot. Its operations answer for roughly 383 metric tons of CO2-equivalent a year.

Read together — 61% complaint, 61 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$3.6M of Kings, written across 6,298 government filings.
