A RegWatch Dossier

45records on file

Completed in 1901, 50 1 St rises 2 stories over Kings. Public records put it at 2 units and 2,088 square feet of floor area, on land zoned R6B. It is carried on the public rolls at a market value of $3.1M, and assessed for tax at $184K. In the 61 years its record reaches back, the lot has drawn 45 separate government filings.

The documentary life of the address leans hard toward mortgage: 9 of its 45 records, fully 20%, fall under that one heading. Lien (9) and permit (7) 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 2013.

Read together — 20% mortgage, 61 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$3.1M of Kings, written across 45 government filings.
