The lot

What is already here?

The lot holds a 3-story one-family home built in 1899, on a 1,980 sq ft lot.

  1. Floors 2–3Nothing on record
  2. Floor 1Street levelStreet level. The lot is recorded as one and two family homes.
  • Street levelOne and two family homes
  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 18.9 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 12.8 m over 3 floors, as the city counts them. 1 run of floors has 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.

What it sold for

The property itself last changed hands for $7,000,000 on Apr 13, 2026.

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

2023 O'CONNELL QSS TRUST

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

Violation record

Are there open violations here?

No open violations are recorded for this building.

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 3007107. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 15 alteration filing. Its latest status categories are 8 recorded as completed, 7 approved. Each filing page preserves its own status, dates, scope and source identifier.
