Completed in 1974, 1721 Amsterdam Ave rises 4 stories over New York. Public records put it at 2 units and 59,209 square feet of floor area, on land zoned R6A. It is carried on the public rolls at a market value of $11.5M, and assessed for tax at $5.2M. In the 54 years its record reaches back, the lot has drawn 337 separate government filings.

The documentary life of the address leans hard toward inspection: 92 of its 337 records, fully 27%, fall under that one heading. Enforcement (66) and violation (63) trail well behind. 15 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 2, with a site energy-use intensity of 239.3 kBtu per square foot. Its operations answer for roughly 1,013 metric tons of CO2-equivalent a year.

Read together — 27% inspection, 54 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.

$11.5M of New York, written across 337 government filings.
