The apartments
158 condominium apartments are assessed on this block, and the typical one is 1,240 sq ft (115 m²). They run from 65 to 207 m².
The city values the typical one at $416,400. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
9 apartments on this tax block changed hands in the year the city last published, at a median of $950,000, from 242,500 to 2,300,000.
The property itself last changed hands for $4,500,000 on Dec 19, 2025.
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
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 1012791. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 5 alteration filing. Its latest status categories are 5 approved. Each filing page preserves its own status, dates, scope and source identifier.
