The lot

What is already here?

The lot holds a 4-story condominium built in 1910, with 4 homes, on a 2,300 sq ft lot.

  1. Floors 2–4Homes4 homes are recorded on this lot — about one home to a floor, and the apartments assessed on this block run to a typical 1,081 sq ft (100 m²). The city does not publish which floor any of them is on.
  2. Floor 1Street levelStreet level. The lot is recorded as walk-up apartments.
  • Street levelWalk-up apartments
  • Homes4 recorded · typically 100 m² · valued $658,625
  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 18.6 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 11.7 m over 4 floors, as the city counts them. 2 runs of floors have something on record. The city publishes a roof height and a storey count for the lot, and nothing at all about any individual floor. What stands to the south is measured from the city’s own footprints and roof heights; it is a statement about the skyline, not a calculation of sunlight.

The apartments

54 condominium apartments are assessed on this block, and the typical one is 1,081 sq ft (100 m²). They run from 75 to 194 m².

The city values the typical one at $658,625. 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 $2,500,000.

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

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 14, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

On the market here

2 homes at this address are currently listed for sale by Coldwell Banker and Douglas Elliman. 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 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.

Violation record

Are there open violations here?

No open violations are recorded for this building. 3 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 records below are grouped because they publish BIN 3005767. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 18 alteration filing. Its latest status categories are 9 recorded as completed, 9 approved. Each filing page preserves its own status, dates, scope and source identifier.
