D.C. Mun. Regs. tit. 14, r. 14-5316
The Family shall request DCHA approval to add a new Family member, with the exception of the addition of a Family member as a result of birth, adoption, foster placement or court-awarded custody. However, in all circumstances the Family is required to notify DCHA of the addition in accordance with chapter 84 of this chapter of the DCMR.
Requests to add adult Family members are subject to DCHA's eligibility requirements at chapter 51 of this title of the DCMR.
DCHA shall only consider a request to add an adult to the Family composition under the following circumstances:
Before DCHA's approval can be finalized, the Family shall obtain the owner's written approval to add a new Family member or a live-in aide.
If the owner declines to approve the addition of a new adult Family member, the Family will be issued a transfer voucher. The new member will be added to the Family composition once the Family member has moved into a new unit.
DCHA shall not add any Family members who claim citizenship or eligible immigration status to the household until a social security number is provided and verified.
