Violation record
Are there open violations here?
No open violations are recorded for this building.
A violation is a notice the Department of Buildings recorded against the building. It is not a judgment, and many concern paperwork rather than safety. Open means the agency has not recorded a resolution, which is not the same as the problem still existing. From NYC Department of Buildings, DOB Violations (3h2n-5cm9), accessed Sep 4, 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 3428957. They should not be read as a single construction project unless the underlying filings say so.
The matched set includes 8 alteration filing. Its latest status categories are 5 approved, 3 recorded as completed. Each filing page preserves its own status, dates, scope and source identifier.
