Completed in 1967, 866 Un Plaza rises 6 stories over New York. Public records put it at 306,964 square feet of floor area, on land zoned C5-2. It is carried on the public rolls at a market value of $6.7M, and assessed for tax at $3.0M. In the 41 years its record reaches back, the lot has drawn 1,450 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 1,082 of its 1,450 records, fully 75%, fall under that one heading. Violation (162) and inspection (69) 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 2021.

On the environmental ledger, the building posts an Energy Star score of 93, with a site energy-use intensity of 33.5 kBtu per square foot. Its operations answer for roughly 4,199 metric tons of CO2-equivalent a year.

Read together — 75% permit, 41 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.

75% of every record here performs the same act: permit.
