Completed in 1959, 41 Kosciuszko St rises 4 stories over Kings. Public records put it at 95 units and 86,826 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $9.8M, and assessed for tax at $4.4M. In the 56 years its record reaches back, the lot has drawn 342 separate government filings.

The documentary life of the address leans hard toward enforcement: 70 of its 342 records, fully 20%, fall under that one heading. Permit (64) and inspection (56) trail well behind. No 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 2009.

On the environmental ledger, the building posts an Energy Star score of 57, with a site energy-use intensity of 44.3 kBtu per square foot. Its operations answer for roughly 363 metric tons of CO2-equivalent a year.

Read together — 20% enforcement, 56 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$9.8M of Kings, written across 342 government filings.
