Completed in 1985, 420 West 23 St rises 11 stories over New York. Public records put it at 45 units and 38,168 square feet of floor area, on land zoned R7B. It is carried on the public rolls at a market value of $275K, and assessed for tax at $124K. In the 41 years its record reaches back, the lot has drawn 955 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward mortgage: 164 of its 955 records, fully 17%, fall under that one heading. Inspection (160) and permit (139) trail well behind. 5 violations stand open against it today.

The pace is anything but even. Activity is spread across the decades, with 1985 the busiest year on file.

On the environmental ledger, the building posts an Energy Star score of 6, with a site energy-use intensity of 93.0 kBtu per square foot. Its operations answer for roughly 328 metric tons of CO2-equivalent a year.

Read together — 17% mortgage, 41 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.

$275K of New York, written across 955 government filings.
