  1. Floors 2–6Homes384 homes are recorded on this lot — about 77 homes to a floor. The city does not publish which floor any of them is on.
  2. Floor 1Street levelStreet level. The lot is recorded as mixed residential and commercial, so this floor is where the commercial space is.
  • Street levelMixed residential and commercial
  • Homes384 recorded on the lot
  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 19.5 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 22.9 m over 6 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

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

  • 0Immediately hazardous
  • 4Hazardous
  • 0Non-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 Nov 1, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

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 4430873. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 9 alteration filing. Its latest status categories are 3 approved, 6 recorded as completed. Each filing page preserves its own status, dates, scope and source identifier.
