Completed in 2009, 23 South 9 St rises 9 stories over Kings. Public records put it at 343,228 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $2.0M, and assessed for tax at $902K. In the 31 years its record reaches back, the lot has drawn 303 separate government filings.

The documentary life of the address leans hard toward permit: 121 of its 303 records, fully 40%, fall under that one heading. Complaint (104) and violation (47) 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 2014.

On the environmental ledger, the building posts an Energy Star score of 41, with a site energy-use intensity of 46.7 kBtu per square foot. Its operations answer for roughly 1,824 metric tons of CO2-equivalent a year.

Read together — 40% permit, 31 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.0M of Kings, written across 303 government filings.
