Completed in 1925, 823 Classon Ave rises 7 stories over Kings. Public records put it at 37 units and 26,271 square feet of floor area, on land zoned R7A. It is carried on the public rolls at a market value of $25.4K, and assessed for tax at $11.4K. In the 36 years its record reaches back, the lot has drawn 230 separate government filings.

The documentary life of the address leans hard toward permit: 75 of its 230 records, fully 33%, fall under that one heading. Enforcement (48) and violation (42) trail well behind. 3 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 2008.

On the environmental ledger, the building posts an Energy Star score of 46, with a site energy-use intensity of 71.2 kBtu per square foot. Its operations answer for roughly 153 metric tons of CO2-equivalent a year.

Read together — 33% permit, 36 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$25.4K of Kings, written across 230 government filings.
