Completed in 1921, 100 Morningside Ave rises 6 stories over New York. Public records put it at 2 units and 128,736 square feet of floor area, on land zoned R7-2. It is carried on the public rolls at a market value of $27.5M, and assessed for tax at $12.4M. In the 37 years its record reaches back, the lot has drawn 935 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 468 of its 935 records, fully 50%, fall under that one heading. Violation (196) and inspection (118) trail well behind. 11 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 2023.

On the environmental ledger, the building posts an Energy Star score of 74, with a site energy-use intensity of 81.3 kBtu per square foot. Its operations answer for roughly 1,118 metric tons of CO2-equivalent a year.

Read together — 50% permit, 37 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.

$27.5M of New York, written across 935 government filings.
