The apartments
592 condominium apartments are assessed on this block, and the typical one is 1,371 sq ft (127 m²). They run from 56 to 512 m².
The city values the typical one at $626,599. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
32 apartments on this tax block changed hands in the year the city last published, at a median of $2,598,688, from 360,000 to 11,415,000.
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.

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.

|---|---|---|---|---|---|
| Whole buildingFor sale | Price not read | RE/MAX |
Read from the brokerages’ own published listings on October 10, 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the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn.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.
Violation record
Are there open violations here?
No open violations are recorded for this building. 17 notices are on file, all with a recorded resolution.
Open means the agency has not recorded a resolution, which is not the same as the problem still existing. What a violation is, and what it is not. From NYC Department of Buildings, DOB Violations (3h2n-5cm9), accessed Sep 23, 2026.
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 matched set includes 3 alteration filing. Its latest status categories are 3 approved. Each filing page preserves its own status, dates, scope and source identifier.
