Described as “very serious in nature,” accounting deficiencies in a grant-funded housing program operated by Hall County were revealed Thursday night in an audit report to the Board of Commissioners. County officials missed a deadline to submit the 2014 fiscal year audit to the state after problems with the Neighborhood Stabilization Program were discovered. According to the audit report, a lack of internal controls and compliance has caused the NSP to run millions of dollars in deficits for the past two years, which have been paid by general fund tax dollars.
