Completed in 1907, 723 St Nicholas Ave rises 6 stories over New York. Public records put it at 40 units and 33,780 square feet of floor area, on land zoned R6A. It is carried on the public rolls at a market value of $3.7M, and assessed for tax at $1.6M. In the 55 years its record reaches back, the lot has drawn 3,534 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 2,036 of its 3,534 records, fully 58%, fall under that one heading. Violation (1,054) and enforcement (216) trail well behind. 106 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 53, with a site energy-use intensity of 102.5 kBtu per square foot. Its operations answer for roughly 218 metric tons of CO2-equivalent a year.

Read together — 58% complaint, 55 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.

$3.7M of New York, written across 3,534 government filings.
