New York, NY —

A Brooklyn Assemblyman who's trying to turn failed condo developments into affordable housing, says he's found 65 buildings that are either stalled, empty, or partially filled.

Hakeem Jeffries says his office did a block by block count of condo projects in his district which includes Fort Greene, Clinton Hill and Prospect Heights. He says a 12-story glass tower known as the Collection at 525 Clinton Avenue is one development that appears to be failing.

JEFFRIES: It has been completed for several months now. Been on the market. No one has moved in and it doesn't appear that there is any hope for anyone to move in.

Karnusa Equities owns 525 Clinton, and when asked if the project is failing, CEO David Weiss would only say "at the end of day everything always works out." The building has a troubled past. A construction worker fell off a scaffold and died there last year.
