Completed in 1954, 485 Throop Ave rises 4 stories over Kings. Public records put it at 1 unit and 69,500 square feet of floor area, on land zoned R6B. It is carried on the public rolls at a market value of $6.5M, and assessed for tax at $2.9M. In the 42 years its record reaches back, the lot has drawn 210 separate government filings.

The documentary life of the address leans hard toward permit: 80 of its 210 records, fully 38%, fall under that one heading. Inspection (50) and violation (40) trail well behind. 9 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 2023.

On the environmental ledger, the building is benchmarked under Local Law 84, with a site energy-use intensity of 94.4 kBtu per square foot. Its operations answer for roughly 273 metric tons of CO2-equivalent a year.

Read together — 38% permit, 42 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$6.5M of Kings, written across 210 government filings.
