Completed in 1910, 680 Jefferson Ave rises 4 stories over Kings. Public records put it at 36 units and 27,792 square feet of floor area, on land zoned R6B. It is carried on the public rolls at a market value of $2.8M, and assessed for tax at $1.3M. In the 61 years its record reaches back, the lot has drawn 1,200 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 664 of its 1,200 records, fully 55%, fall under that one heading. Violation (383) and inspection (44) trail well behind. 49 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 2020.

On the environmental ledger, the building posts an Energy Star score of 44, with a site energy-use intensity of 90.0 kBtu per square foot. Its operations answer for roughly 162 metric tons of CO2-equivalent a year.

Read together — 55% complaint, 61 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.8M of Kings, written across 1,200 government filings.
