The DOB has cordoned off the vacant building at 647 Baltic Street in Park Slope with its scary yellow tape and the official line on the structure, via a spokesperson, is that it “prevents a significant safety risk” but it’s “not in imminent danger of collapse.” The building’s owner, who, according to neighbors, hasn’t been seen for a couple years, has been served with a bunch of violations. One of the more recent ones says the following: “Failure to maintain observed: front brick facade pulling away from side wall with vertical crack app. 20′ high with gaps from 3/8″ to 1 1/2″.” The DOB says they’re evaluating their options for the building, which may very well include demolition.
