Sunset Park (West), Brooklyn
A consolidated public-record view · updated Aug 24, 2026
A building-level summary of matched filings, active-status records and published identifiers.
The lot
The lot holds a 3-story educational building built in 2022, on a 12,521 sq ft lot.
The apartments
16 condominium apartments are assessed on this block, and the typical one is 630 sq ft (59 m²). They run from 59 to 106 m².
The city values the typical one at $234,250. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
1 apartment on this tax block changed hands in the year the city last published, at a median of $320,000.
Recorded sale prices from the Department of Finance’s rolling file, covering the year to Aug 31, 2026. Transfers under $10,000 are left out: New York records deed transfers between relatives at a dollar, and those are not sales. No apartment number and no name is carried from either side.

What is recorded here
New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work. The records below are grouped because they publish BIN 3426350. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 14 alteration filing. Its latest status categories are 3 recorded as completed, 10 approved, 1 closed or withdrawn. Each filing page preserves its own status, dates, scope and source identifier.
Highest recorded values may come from different filings and must not be combined into one proposed project. Open the individual filings below for their exact scope. Values outside the publication's conservative data-quality bounds are withheld pending source review.
