The documentary life of the address leans hard toward permit: 135 of its 458 records, fully 29%, fall under that one heading. Enforcement (127) and violation (90) trail well behind. 11 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 — 29% permit, 33 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$45.6M of New York, written across 458 government filings.
