Livingston Park Apartments comprises 195 units in 11 buildings. Ten of the buildings were built in the 1940s and offer low-rent apartments. The 11th building, comprising 15 apartments built within the last decade, charges market-rate rents. The Finch Group, of Florida, is planning a $12-million redevelopment project — including putting new roofs on the 10 older buildings, replacing the heating systems and adding air-conditioning systems.
