An overhaul of the DeKalb County Jail to fix issues with leaky plumbing and mold was announced by Sheriff Jeffrey Mann today.

The renovation will cost $1.5 million and is expected to take three months. Mann said that a study concluded the mold is likely caused by leaks in the showers where inmates are housed but poses no immediate health threats.

The 1 million-square-foot detention center is located on Memorial Drive and has an average daily population of 1,800, well below its capacity. The jail was built 23 years ago.
