St. James Towers co-op in Brooklyn votes to stick with Mitchell-Lama.

St. James Towers is latest to vote on whether to stay affordable or cash in.

Adrian Griffith, the current president of the Ryerson Towers board, joined after the earlier capital improvements were already under way. The 326-unit Mitchell-Lama co-op in the Clinton Hill section of Brooklyn set out on a $3.5 million project to replace the windows and the boiler, do façade work, resurface balconies, and redo the roof. The 2008 loan for that work was secured from the city's Department of Housing Preservation and Development (HPD), which did not require the board to hire a construction manager. This time the loan — a refinancing of the underlying mortgage plus money for anticipated capital improvements — came from the city's Housing Development Corporation (HDC).

It was a massive job. Seven years ago, the board at Ryerson Towers, a 326-unit Mitchell-Lama co-op in the Clinton Hill section of Brooklyn, set out on a $3.5 million project to replace the windows and the boiler, do façade work, resurface balconies, and redo the roof. The job of coordinating the various contractors and overseeing the work fell to the property manager, Dahlia Lyons-Harrison, of New Bedford Management. Looking back, she remembers it as a largely successful — but stressful — assignment.

Today, as Ryerson Towers embarks on an even bigger job — a job that will take two years and $7.3 million.
