- Local law 62/91 - boilers
Issued Aug 16, 1993
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 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 matched set includes 6 alteration filing. Its latest status categories are 4 recorded as completed, 1 closed or withdrawn, 1 approved. Each filing page preserves its own status, dates, scope and source identifier.
