D.C. Mun. Regs. r. 14-1922
In addition to the unit inspections required prior to initial Contract execution, DCHA shall inspect each unit under Contract at least annually and at other times as necessary to assure that the housing provider is meeting the obligation to maintain the unit in decent, safe and sanitary condition. The tenant shall cooperate with inspections at reasonable times and after reasonable notice.
DCHA shall take into consideration complaints and any other information coming to its attention in scheduling inspections.
If DCHA notifies the housing provider that a unit under Contract is not being maintained in decent, safe and sanitary condition and the housing provider fails to take corrective action (including corrective action with respect to the tenant where the condition of the unit is the fault of the tenant) within a period of time prescribed by DCHA, DCHA may suspend assistance payments to the housing provider as provided for in § 1931.
