Board members who oversee the Charlotte Housing Authority said they recently discovered a 2008 audit that found major problems with the non-profit's voucher program.
The study revealed errors that may have allowed criminals or those earning too much to qualify for public housing.
Administrators told the federal government the program was nearly perfect.
It is not clear if the problems were ever corrected. The board has ordered a new audit.
The housing authority sent Channel 9 this statement in regard to the new audit:
"CHA will be constantly seeking efficiencies and ways to better serve our customers, which is why having Quadel review our programs is a prudent management practice to ensure the continued success of the Charlotte Housing Authority."
