Completed in 2006, 660 Louisiana Ave rises 4 stories over Kings. Public records put it at 1 unit and 125,836 square feet of floor area, on land zoned R5. It is carried on the public rolls at a market value of $61.7M, and assessed for tax at $27.7M. In the 35 years its record reaches back, the lot has drawn 249 separate government filings.

The documentary life of the address leans hard toward inspection: 64 of its 249 records, fully 26%, fall under that one heading. Permit (55) and violation (40) 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 87, with a site energy-use intensity of 59.0 kBtu per square foot. Its operations answer for roughly 755 metric tons of CO2-equivalent a year.

Read together — 26% inspection, 35 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$61.7M of Kings, written across 249 government filings.
