Completed in 1923, 266 Madison Ave rises 19 stories over New York. Public records put it at 3 units and 210,068 square feet of floor area, on land zoned C5-3. It is carried on the public rolls at a market value of $10.4M, and assessed for tax at $4.7M. In the 73 years its record reaches back, the lot has drawn 1,312 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 726 of its 1,312 records, fully 55%, fall under that one heading. Enforcement (178) and inspection (173) trail well behind. 3 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 70, with a site energy-use intensity of 61.4 kBtu per square foot. Its operations answer for roughly 1,610 metric tons of CO2-equivalent a year.

Read together — 55% permit, 73 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.

$10.4M of New York, written across 1,312 government filings.
