The apartments
16 condominium apartments are assessed on this block, and the typical one is 1,868 sq ft (174 m²). They run from 79 to 189 m².
The city values the typical one at $1,181,750. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
10 apartments on this tax block changed hands in the year the city last published, at a median of $1,889,000, from 710,000 to 8,000,000.
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.

Read from the brokerages’ own published listings on October 2, 2026. A home drops off this table the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn. What we know is that it is no longer offered, which is why this shows what they have today rather than what we were told once. Everything on the market across the city.

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 1046787. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 4 alteration filing. Its latest status categories are 2 recorded as completed, 2 approved. Each filing page preserves its own status, dates, scope and source identifier.
