897records on file

Completed in 1915, 346 Madison Ave rises 11 stories over New York. Public records put it at 1 unit and 140,280 square feet of floor area, on land zoned C5-3. It is carried on the public rolls at a market value of $70.1M, and assessed for tax at $31.5M. In the 43 years its record reaches back, the lot has drawn 897 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 385 of its 897 records, fully 43%, fall under that one heading. Violation (267) and enforcement (118) trail well behind. 23 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 2026.

On the environmental ledger, the building is benchmarked under Local Law 84, with a site energy-use intensity of 35.5 kBtu per square foot. Its operations answer for roughly 386 metric tons of CO2-equivalent a year.

Read together — 43% permit, 43 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.

$70.1M of New York, written across 897 government filings.
