Owner of record

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 Oct 15, 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 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 3430459. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 8 new building, 1 alteration filing. Its latest status categories are 4 recorded as completed, 5 approved. Each filing page preserves its own status, dates, scope and source identifier.
