Completed in 2007, 991 Willoughby Ave rises 10 stories over Kings. Public records put it at 37 units and 35,993 square feet of floor area, on land zoned R6. It is carried on the public rolls at a market value of $7.2M, and assessed for tax at $3.2M. In the 57 years its record reaches back, the lot has drawn 349 separate government filings.

The documentary life of the address leans hard toward inspection: 80 of its 349 records, fully 23%, fall under that one heading. Permit (69) and violation (47) trail well behind. 4 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 2013.

On the environmental ledger, the building posts an Energy Star score of 83, with a site energy-use intensity of 54.0 kBtu per square foot. Its operations answer for roughly 144 metric tons of CO2-equivalent a year.

Read together — 23% inspection, 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.

$7.2M of Kings, written across 349 government filings.
