The Turk and Eddy apartment buildings are two separate mid-rise buildings built in 1923 and 1925 in San Francisco’s Tenderloin neighborhood, providing 82 affordable studio and one-bedroom apartments for extremely low-income seniors. In 2007, after the property faced the threat of converting to market-rate, the Tenderloin Neighborhood Development Corporation (TNDC) stepped in to preserve it with the help of federal stimulus and redevelopment funds.
