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.

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 5, 2026.
