Completed in 1908, 11 Adelphi St rises 3 stories over Kings. Public records put it at 4 units and 27,422 square feet of floor area, on land zoned M1-2. It is carried on the public rolls at a market value of $4.4M, and assessed for tax at $2.0M. In the 59 years its record reaches back, the lot has drawn 109 separate government filings.

The documentary life of the address leans hard toward permit: 44 of its 109 records, fully 40%, fall under that one heading. Violation (17) and enforcement (17) 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 2021.

On the environmental ledger, the building posts an Energy Star score of 80, with a site energy-use intensity of 61.0 kBtu per square foot. Its operations answer for roughly 110 metric tons of CO2-equivalent a year.

Read together — 40% permit, 59 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$4.4M of Kings, written across 109 government filings.
