We performed a review of the San Diego Square (Square) project in response to a hotline complaint. The complainant stated that San Diego Kind Corporation (Corporation) misappropriated a lease prepayment of $480,060 and HUD failed to enforce program rules and regulations after detecting the misappropriation. Our objective was to determine whether the complaint was valid. We were unable to determine whether the allegations were valid. The sublease transaction occurred over 20 years ago, so many of the project records could not be located or are no longer available. Therefore, we could not make a final determination as to whether the hotline complaint was valid. As a result, it is incumbent upon HUD to resolve this matter by making a final determination on whether the subleased area was or was not built and insured under the Section 202 loan. We recommend that HUD make a final determination and provide official written notification to the Corporation as to whether the subleased area of the Square is considered part of the Section 202-insured project and, therefore, rental revenue it received in the past, and will receive in the future, for use of space on the project must be recognized as project income.
