Completed in 1911, 28 Jefferson Ave rises 6 stories over Kings. Public records put it at 61 units and 54,200 square feet of floor area, on land zoned R6A. It is carried on the public rolls at a market value of $4.6M, and assessed for tax at $2.1M. In the 53 years its record reaches back, the lot has drawn 780 separate government filings.

The documentary life of the address leans hard toward violation: 334 of its 780 records, fully 43%, fall under that one heading. Complaint (279) and permit (55) trail well behind. 10 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 2011.

Read together — 43% violation, 53 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$4.6M of Kings, written across 780 government filings.
