Completed in 1932, 121 Seaman Ave rises 6 stories over New York. Public records put it at 42 units and 36,793 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $5.1M, and assessed for tax at $2.3M. In the 54 years its record reaches back, the lot has drawn 1,324 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 851 of its 1,324 records, fully 64%, fall under that one heading. Violation (276) and enforcement (58) trail well behind. 69 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 99, with a site energy-use intensity of 41.1 kBtu per square foot. Its operations answer for roughly 105 metric tons of CO2-equivalent a year.

Read together — 64% complaint, 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.

$5.1M of New York, written across 1,324 government filings.
