Completed in 2015, 21 Hinckley Pl rises 5 stories over Kings. Public records put it at 1 unit and 92,028 square feet of floor area, on land zoned R5. It is carried on the public rolls at a market value of $32.0M, and assessed for tax at $14.4M. In the 55 years its record reaches back, the lot has drawn 336 separate government filings.

The documentary life of the address leans hard toward permit: 93 of its 336 records, fully 28%, fall under that one heading. Enforcement (60) and complaint (39) trail well behind. 1 violation stands 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 3, with a site energy-use intensity of 105.2 kBtu per square foot. Its operations answer for roughly 1,028 metric tons of CO2-equivalent a year.

Read together — 28% permit, 55 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$32.0M of Kings, written across 336 government filings.
