Completed in 1912, 420 Riverside Dr rises 13 stories over New York. Public records put it at 104 units and 138,633 square feet of floor area, on land zoned R8. It is carried on the public rolls at a market value of $22.0M, and assessed for tax at $9.9M. In the 55 years its record reaches back, the lot has drawn 870 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 312 of its 870 records, fully 36%, fall under that one heading. Inspection (278) and violation (100) trail well behind. 21 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 2016.

On the environmental ledger, the building posts an Energy Star score of 78, with a site energy-use intensity of 82.8 kBtu per square foot. Its operations answer for roughly 772 metric tons of CO2-equivalent a year.

Read together — 36% permit, 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.

$22.0M of New York, written across 870 government filings.
