In the 37 years its record reaches back, the lot has drawn 1,123 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 768 of its 1,123 records, fully 68%, fall under that one heading. Enforcement (70) and sale (63) trail well behind. 4 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 2008.

Read together — 68% permit, 37 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.

68% of every record here performs the same act: permit.
