The apartments

106 condominium apartments are assessed on this block, and the typical one is 841 sq ft (78 m²). They run from 34 to 327 m².

The city values the typical one at $412,362. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.

What it sold for

2 apartments on this tax block changed hands in the year the city last published, at a median of $4,251,194.

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.

As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.

Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 21, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

Read from the brokerages’ own published listings on September 21, 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the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn.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. 2 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 21, 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 records below are grouped because they publish BIN 3429034. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 8 alteration filing. Its latest status categories are 6 recorded as completed, 2 approved. Each filing page preserves its own status, dates, scope and source identifier.
