Stalled construction projects have become a fixture of the New York City streetscape in the aftermath of the real estate bust, but upkeep on the partially-built structures has proven a costly task. The city spent approximately $10,000 on each of 75 buildings dangerously close to collapse between June 2008 and June 2009, according to the Department of Housing Preservation and Development. The funds went toward emergency scaffolding sheds. Only 27 such reinforcements were needed during the same period in 2007. An additional 75 buildings were demolished at an average of $49,000 each during fiscal year 2009, up from 53 in fiscal year 2008, the Post reported. Squatters are also proving costly, with 47 abandoned buildings needing roughly $2,000 that went toward sealing doors and windows over the past fiscal year. Still, such efforts haven’t eliminated the dangers of neglected construction sites. At least 15 pedestrians have reported being hit with falling debris from city properties this year, Department of Buildings records show.
