Representatives of the company that owns Patten Towers said residents of the 11-story, low-income apartment building won't be able to move back into their homes for six to eight weeks.
PK Management officials said this morning that an electrical switch must be custom built.
On Tuesday, the 241 residents of Patten Towers were evacuated after an electrical fire burned out of control in the basement of the building. They are staying at a shelter at Brainerd Recreation Center.
A news conference at the center will be held soon. Chattanooga Mayor Andy Berke and other officials will be on hand to answer questions.
