It is carried on the public rolls at a market value of $2.8M, and assessed for tax at $1.3M. In the 46 years its record reaches back, the lot has drawn 334 separate government filings.

The documentary life of the address leans hard toward complaint: 85 of its 334 records, fully 25%, fall under that one heading. Permit (80) and violation (77) trail well behind. 45 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 100, with a site energy-use intensity of 16.4 kBtu per square foot. Its operations answer for roughly 41 metric tons of CO2-equivalent a year.

Read together — 25% complaint, 46 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.

$2.8M of New York, written across 334 government filings.
