The apartments
82 condominium apartments are assessed on this block, and the typical one is 983 sq ft (91 m²). They run from 46 to 187 m².
The city values the typical one at $293,303. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
Owner of record
DECADE DEVELOPMENT LLC, AS DESIGNEE
As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.
Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Oct 30, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

What is recorded here
Multiple filings, one stable building identifier.
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 3337514. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 2 alteration filing, 2 full demolition. Its latest status categories are 4 approved. Each filing page preserves its own status, dates, scope and source identifier.
