Since August 2008, the front of the Department of Buildings' headquarters in lower Manhattan has been covered by a sidewalk shed. The unsightly steel-and-wood structure outside 280 Broadway stood because for years the city had set aside no money to pay to fix the crumbling facade.

"Thankfully, work has commenced as of a few months ago," Patrick Wehle, an assistant buildings commissioner, said at a City Council hearing last week. But the point had been made: Because it's much costlier to fix a façade than to maintain a shed that devours sidewalk space, blocks sunlight and hurts businesses, and no deadline to remove it, sheds have spread across the city. There are now 8,843—about 200 miles worth—and they pop up any time a building is built or repaired, as Crain's documented in a cover story last year.

Late last year City Councilman Ben Kallos sponsored a bill to stop the scourge and last week a hearing was finally held to discuss it.
