Completed in 1930, 505 Ct St rises 10 stories over Kings. Public records put it at 124 units and 134,943 square feet of floor area, on land zoned R6A. It is carried on the public rolls at a market value of $387K, and assessed for tax at $174K. In the 44 years its record reaches back, the lot has drawn 2,518 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward mortgage: 740 of its 2,518 records, fully 29%, fall under that one heading. Release (509) and assignment (419) trail well behind. 39 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 2007.

On the environmental ledger, the building posts an Energy Star score of 43, with a site energy-use intensity of 85.8 kBtu per square foot. Its operations answer for roughly 848 metric tons of CO2-equivalent a year.

Read together — 29% mortgage, 44 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$387K of Kings, written across 2,518 government filings.
