The lot

What is already here?

The lot holds a vacant land on a 2,585 sq ft lot.

  1. Floors 3–4Above the southern skylineAbove the tallest building within sixty metres to the south, which stands 7.9 m. Nothing on that side reaches this floor.
  2. Floor 2Nothing on record
  3. Floor 1Street levelStreet level. The lot is recorded as vacant land.
  • Street levelVacant land
  • Above the southern skylineFrom about floor 3 — the tallest thing within 60 m to the south is 7.9 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 12.5 m over about 4 floors, counted at three metres each because the city publishes the height and not the number. 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.

Housing violations

10 violations are open against this address under the Housing Maintenance Code.

  • 0Immediately hazardous
  • 0Hazardous
  • 5Non-hazardous
  • 5Information 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.

Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Oct 20, 2026. They describe the tax lot, not any single filing.

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 Oct 19, 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 3190444. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 4 new building, 2 alteration filing. Its latest status categories are 5 approved, 1 under review. Each filing page preserves its own status, dates, scope and source identifier.
