Completed in 1917, 511 5 Ave rises 17 stories over New York. Public records put it at 2 units and 125,632 square feet of floor area, on land zoned C5-3. It is carried on the public rolls at a market value of $34.4M, and assessed for tax at $15.5M. In the 58 years its record reaches back, the lot has drawn 805 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 309 of its 805 records, fully 38%, fall under that one heading. Violation (149) and inspection (137) trail well behind. 28 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 2025.

On the environmental ledger, the building posts an Energy Star score of 88, with a site energy-use intensity of 63.6 kBtu per square foot. Its operations answer for roughly 568 metric tons of CO2-equivalent a year.

Read together — 38% 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.

$34.4M of New York, written across 805 government filings.
