D.C. Mun. Regs. tit. 14, r. 14-6203
Each new tenant household shall be required to make a security deposit to DCHA prior to the execution of the dwelling lease.
The security deposit shall be a flat fee assessment as follows:
The security deposit shall be due in full at the time of the execution of the dwelling lease.
The security deposit shall be retained by DCHA until the tenant vacates the unit.
Whenever a tenant is relocated from one (1) DCHA unit to another, the tenant may choose to have the security deposit transferred to the new unit and dwelling lease agreement.
If the unit from which the tenant is transferring has tenant caused damages, or there are other unpaid charges due from the tenant, DCHA may deduct those amounts due as provided in § 6204 of this chapter, and require a new security deposit from the tenant prior to execution of a new lease for the unit to which the tenant is moving.
