But sidewalk sheds have been known to overstay their welcome, like a drunken uncle, sometimes sticking around for a dozen years or more, providing magnets for drug dealers, homeless people, trash, and worse. To remedy the situation, city councilman Ben Kallos, who represents the Upper East Side, proposed a new law on Tuesday that would give building owners three months, with the possibility of a three-month extension, to make repairs and remove scaffolding and sidewalk sheds, the New York Times reports. If the work is not completed in that time, the city will step in to do it, and charge the owner for the work.
