Completed in 1930, 234 Duffield St rises 7 stories over Kings. Public records put it at 122 units and 266,456 square feet of floor area, on land zoned C6-4.5. It is carried on the public rolls at a market value of $40.6M, and assessed for tax at $18.3M. In the 57 years its record reaches back, the lot has drawn 1,747 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 479 of its 1,747 records, fully 27%, fall under that one heading. Violation (359) and inspection (274) trail well behind. 6 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 68, with a site energy-use intensity of 50.8 kBtu per square foot. Its operations answer for roughly 1,441 metric tons of CO2-equivalent a year.

Read together — 27% permit, 57 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$40.6M of Kings, written across 1,747 government filings.
