- 0Information order
Open means the Department of Housing Preservation and Development has not recorded it as corrected, which is not the same as nobody having fixed it. The city publishes the apartment each was written against; that is not carried here, because a count says a building has a problem and an apartment number says whose.
The apartments
4 condominium apartments are assessed on this block, and the typical one is 703 sq ft (65 m²). They run from 45 to 88 m².
The city values the typical one at $178,427. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.
What it sold for
31 apartments on this tax block changed hands in the year the city last published, at a median of $745,000, from 340,000 to 4,000,000.
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.
Owner of record
LUDLOW PLACE CORP.
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.

Read from the brokerages’ own published listings on October 3, 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the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn.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 1085199. 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 under review, 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
