It is carried on the public rolls at a market value of $10.8M, and assessed for tax at $4.9M. In the 53 years its record reaches back, the lot has drawn 1,711 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,103 of its 1,711 records, fully 64%, fall under that one heading. Violation (391) and permit (68) trail well behind. 36 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 2017.

On the environmental ledger, the building posts an Energy Star score of 1, with a site energy-use intensity of 189.2 kBtu per square foot. Its operations answer for roughly 1,959 metric tons of CO2-equivalent a year.

Read together — 64% complaint, 53 years of accumulation, a parcel of Bronx — these scattered records compose a portrait of the address that no single page sets out to draw.
