Completed in 2005, 517 West 42 St rises 19 stories over New York. Public records put it at 73 units and 94,132 square feet of floor area, on land zoned C6-4. It is carried on the public rolls at a market value of $1.6M, and assessed for tax at $741K. In the 38 years its record reaches back, the lot has drawn 1,887 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,117 of its 1,887 records, fully 59%, fall under that one heading. Violation (429) and inspection (117) trail well behind. 89 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 2023.

On the environmental ledger, the building posts an Energy Star score of 72, with a site energy-use intensity of 56.1 kBtu per square foot. Its operations answer for roughly 388 metric tons of CO2-equivalent a year.

Read together — 59% complaint, 38 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.

$1.6M of New York, written across 1,887 government filings.
