Completed in 1926, 541 Isham St rises 5 stories over New York. Public records put it at 46 units and 36,500 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $2.7M, and assessed for tax at $1.2M. In the 61 years its record reaches back, the lot has drawn 2,280 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 1,263 of its 2,280 records, fully 55%, fall under that one heading. Violation (721) and inspection (123) trail well behind. 135 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 2024.

On the environmental ledger, the building posts an Energy Star score of 29, with a site energy-use intensity of 110.4 kBtu per square foot. Its operations answer for roughly 321 metric tons of CO2-equivalent a year.

Read together — 55% complaint, 61 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.

$2.7M of New York, written across 2,280 government filings.
