  • Above the southern skylineFrom about floor 15 — the tallest thing within 60 m to the south is 43 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 10.5 m over 14 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.

Housing violations

19 violations are open against this address under the Housing Maintenance Code. 1 of them is the class the city calls immediately hazardous.

  • 1Immediately hazardous
  • 14Hazardous
  • 4Non-hazardous
  • 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.

Owner of record

NYC HOUSING AUTHORITY

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 26, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

Violation record

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 25, 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 3328027. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 10 alteration filing. Its latest status categories are 7 approved, 3 recorded as completed. Each filing page preserves its own status, dates, scope and source identifier.
