Completed in 1931, 3420 Clarendon Rd rises 4 stories over Kings. Public records put it at 42 units and 31,814 square feet of floor area, on land zoned R4. It is carried on the public rolls at a market value of $2.1M, and assessed for tax at $963K. In the 95 years its record reaches back, the lot has drawn 1,451 separate government filings — a paper trail nearly as tall as the building itself.

The documentary life of the address leans hard toward complaint: 795 of its 1,451 records, fully 55%, fall under that one heading. Violation (491) and enforcement (36) trail well behind. 24 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 2014.

On the environmental ledger, the building posts an Energy Star score of 100, with a site energy-use intensity of 12.2 kBtu per square foot. Its operations answer for roughly 45 metric tons of CO2-equivalent a year.

Read together — 55% complaint, 95 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$2.1M of Kings, written across 1,451 government filings.
