Completed in 1910, 251 Park Ave South rises 16 stories over New York. Public records put it at 17 units and 103,384 square feet of floor area, on land zoned C6-4A. It is carried on the public rolls at a market value of $65.3M, and assessed for tax at $29.4M. In the 58 years its record reaches back, the lot has drawn 825 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 467 of its 825 records, fully 57%, fall under that one heading. Violation (125) and enforcement (117) trail well behind. 13 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 2017.

On the environmental ledger, the building posts an Energy Star score of 92, with a site energy-use intensity of 47.4 kBtu per square foot. Its operations answer for roughly 498 metric tons of CO2-equivalent a year.

Read together — 57% permit, 58 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.

$65.3M of New York, written across 825 government filings.
