Completed in 1900, 421 Audubon Ave rises 5 stories over New York. Public records put it at 40 units and 29,274 square feet of floor area, on land zoned R7-2. It is carried on the public rolls at a market value of $1.6M, and assessed for tax at $718K. In the 47 years its record reaches back, the lot has drawn 2,535 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,605 of its 2,535 records, fully 63%, fall under that one heading. Violation (698) and enforcement (67) trail well behind. 35 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 2008.

On the environmental ledger, the building is benchmarked under Local Law 84, with a site energy-use intensity of 110.7 kBtu per square foot. Its operations answer for roughly 237 metric tons of CO2-equivalent a year.

Read together — 63% complaint, 47 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 2,535 government filings.
