Completed in 1970, 100 West 50 St rises 54 stories over New York. Public records put it at 1,793,091 square feet of floor area, on land zoned C6-5.5. It is carried on the public rolls at a market value of $23.9M, and assessed for tax at $10.7M. In the 55 years its record reaches back, the lot has drawn 1,510 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 1,385 of its 1,510 records, fully 92%, fall under that one heading. Complaint (52) and violation (41) 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 1997.

On the environmental ledger, the building posts an Energy Star score of 77, with a site energy-use intensity of 65.9 kBtu per square foot. Its operations answer for roughly 14,850 metric tons of CO2-equivalent a year.

Read together — 92% permit, 55 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.

92% of every record here performs the same act: permit.
