The lot

What is already here?

  1. Floors 2–4Nothing on record
  2. Floor 1Street levelStreet level.
  • Street levelThe way in
  • Above the southern skylineFrom about floor 5 — the tallest thing within 60 m to the south is 12.2 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 12.3 m over about 4 floors, counted at three metres each because the city publishes the height and not the number. 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.

Violation record

Are there open violations here?

No open violations are recorded for this building. 1 notice is 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 3074801. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 12 alteration filing. Its latest status categories are 6 recorded as completed, 6 approved. Each filing page preserves its own status, dates, scope and source identifier.
