- Low pressure boiler
Issued Nov 14, 2025 — VIOLATION ISSUED-FAILURE TO FILE 2024 EXTERNAL LOW PRESSURE INSPECTION
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
