Upkeep at Affordable Building on Waterfront

A tipster sent in these photos of a building on the Columbia Street Waterfront that seems to be getting some work done. An affordable housing banner from the New York City Department of Housing Preservation and Development hangs on the scaffolding. We thought maybe this eight-unit building at 143 Columbia Street was being converted into affordable housing, but it appears that already happened in the early ’90s and the brick facade is merely being repointed. As far as we can tell, the building was converted in the early ’90s by the Carroll Gardens Association Inc. The current owner is the South Brooklyn Renewal Housing Development Fund Corp., and the only permits filed since the early ’90s are ones for repointing and a sidewalk shed. Anyone have any more information?
