The documentary life of the address leans hard toward inspection: 22 of its 38 records, fully 58%, fall under that one heading. Permit (8) and enforcement (5) trail well behind. No 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 2022.

Read together — 58% inspection, 19 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.4M of Kings, written across 38 government filings.
