In the 96 years its record reaches back, the lot has drawn 2,221 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,272 of its 2,221 records, fully 57%, fall under that one heading. Violation (691) and enforcement (73) trail well behind. 168 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 2026.

Read together — 57% complaint, 96 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$7.6M of Kings, written across 2,221 government filings.
