Completed in 2008, 511 9 Ave rises 12 stories over New York. Public records put it at 113 units and 144,243 square feet of floor area, on land zoned C1-7A. It is carried on the public rolls at a market value of $15.3M, and assessed for tax at $6.9M. In the 37 years its record reaches back, the lot has drawn 563 separate government filings.

The documentary life of the address leans hard toward enforcement: 179 of its 563 records, fully 32%, fall under that one heading. Complaint (111) and inspection (101) trail well behind. 17 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 2022.

On the environmental ledger, the building posts an Energy Star score of 42, with a site energy-use intensity of 71.7 kBtu per square foot. Its operations answer for roughly 1,007 metric tons of CO2-equivalent a year.

Read together — 32% enforcement, 37 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.

$15.3M of New York, written across 563 government filings.
