Completed in 1931, 850 Amsterdam Ave rises 20 stories over New York. Public records put it at 124 units and 82,172 square feet of floor area, on land zoned R8. It is carried on the public rolls at a market value of $16.5M, and assessed for tax at $7.4M. In the 92 years its record reaches back, the lot has drawn 918 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 445 of its 918 records, fully 48%, fall under that one heading. Inspection (155) and violation (117) trail well behind. 1 violation stands 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 2004.

On the environmental ledger, the building posts an Energy Star score of 93, with a site energy-use intensity of 65.7 kBtu per square foot. Its operations answer for roughly 357 metric tons of CO2-equivalent a year.

Read together — 48% complaint, 92 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.

$16.5M of New York, written across 918 government filings.
