As a byproduct of Local Law 11, there’s an emphasis on repairing leaks or water penetration, because water is known to cause the kind of structural defects that could lead to materials falling from the facades.
Before any repair work can begin, permits are needed from the DOB. If your building happens to be a landmarked building, it requires one from the Landmarks Preservation Commission (LPC) as well.
Facade restoration is time consuming and costly. From the time of inspection to work beginning can often be many months.
My building, a condop on the Upper West Side, built in 1989 is currently about 1 year into a 24 month $million+ noisy and dusty project.
Local Law 11 and its predecessor Local Law 10 has helped make the glass, stone and steel buildings of New York City safer for the men, women and children on the ground below. The sky is no longer falling in NYC.
