On the market here
One home at this address is currently listed for sale by RE/MAX. Prices move; the brokerage’s own page is the one that is current, and every row here links to it.

Read from the brokerages’ own published listings on September 22, 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the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn.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 3117628. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 2 alteration filing. Its latest status categories are 1 recorded as completed, 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
