Completed in 1910, 148 West 23RD St rises 12 stories over New York. Public records put it at 107 units and 127,000 square feet of floor area, on land zoned C6-3X. It is carried on the public rolls at a market value of $34.3M, and assessed for tax at $15.4M. In the 96 years its record reaches back, the lot has drawn 839 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 471 of its 839 records, fully 56%, fall under that one heading. Complaint (91) and inspection (91) trail well behind. 7 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 2022.

On the environmental ledger, the building posts an Energy Star score of 53, with a site energy-use intensity of 57.8 kBtu per square foot. Its operations answer for roughly 1,132 metric tons of CO2-equivalent a year.

Read together — 56% permit, 96 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.

$34.3M of New York, written across 839 government filings.
