D.C. Mun. Regs. tit. 14, § 8408
8408.1 In order to determine the adjusted Annual Income of any Participant family either upon initial certification or upon any examination as set forth in this Chapter, and except as otherwise provided in the Administrative Plan, adopted pursuant to 24 CFR § 982.54, the DCHA is required to obtain and retain in the file of each Family, documentation which provides third party verification of the following:
8408.2 If third party verification is not complete or available for income or assets, DCHA must document the efforts made to obtain such verification. Income can be included without verification. Deductions, allowances or other factors affecting adjusted gross income are not allowed without third party verification.
8408.3 Verifications may be required, at the discretion of DCHA, more frequently than annually for certain types of certifications, such as a self-certification of zero ($0) Annual Income for the household.
8408.4 DCHA allows ten (10) business Days for the return of third party verifications or any Participant family documents or certifications.
8408.5 Verifications may not be more than one hundred twenty (120) Days old at the time a voucher is issued.
8408.6 Income information provided by the Family will be verified using the HUD approved Upfront Income Verification method (UIV). This includes verification from HUD's computerized Enterprise Income Verification System, similar District of Columbia government computer based systems and non-government web based systems. Family provided income information will be verified as follows:
(c) Verification of required family information concerning assets, Full Time Student status, medical expenses, requests for larger units, preference status, and zero ($0) income status shall be obtained by written third party verification. If the written third party verification is unobtainable after diligent efforts by DCHA then the hierarchy in (b)(ii), (iii) and (iv) of this Subsection shall be followed.
