Completed in 1949, 505 Park Ave rises 21 stories over New York. Public records put it at 44 units and 220,510 square feet of floor area, on land zoned C5-3. It is carried on the public rolls at a market value of $78.4M, and assessed for tax at $35.3M. In the 60 years its record reaches back, the lot has drawn 1,293 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward permit: 840 of its 1,293 records, fully 65%, fall under that one heading. Inspection (185) and enforcement (107) trail well behind. No 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 2011.

On the environmental ledger, the building posts an Energy Star score of 87, with a site energy-use intensity of 42.6 kBtu per square foot. Its operations answer for roughly 911 metric tons of CO2-equivalent a year.

Read together — 65% permit, 60 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.

65% of every record here performs the same act: permit.
