The apartments
114 condominium apartments are assessed on this block, and the typical one is 618 sq ft (57 m²). They run from 38 to 106 m².
The city values the typical one at $206,131. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
3 apartments on this tax block changed hands in the year the city last published, at a median of $990,000, from 95,000 to 1,465,000.
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 1, 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the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn.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

No open violations are recorded for this building. 8 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 14, 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 5 alteration filing. Its latest status categories are 4 recorded as completed, 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
