Completed in 1974, 34 Kosciuszko St rises 1 story over Kings. Public records put it at 1 unit and 28,200 square feet of floor area, on land zoned R6B. It is carried on the public rolls at a market value of $5.0M, and assessed for tax at $2.2M. In the 58 years its record reaches back, the lot has drawn 97 separate government filings.

The documentary life of the address leans hard toward inspection: 31 of its 97 records, fully 32%, fall under that one heading. Permit (18) and violation (15) trail well behind. 3 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 2017.

On the environmental ledger, the building posts an Energy Star score of 18, with a site energy-use intensity of 61.8 kBtu per square foot. Its operations answer for roughly 174 metric tons of CO2-equivalent a year.

Read together — 32% inspection, 58 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$5.0M of Kings, written across 97 government filings.
