  • Failure to post energy

    Issued Dec 1, 2021 — FAILURE TO DISPLAY ENERGY EFFICIENCY SCORE AND ENERGY EFFICIENCY GRADE AS PER ADCODE SEC. 28-309.12.3

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.
