14 DCMR § 14-3907
INTERVENORS
Operative Text
3907.1 There shall be no intervenors as a matter of right in Rental Accommodations Division proceedings, but intervenors may be permitted to participate in the proceeding prior to a hearing if the proceedings will directly affect their rights or duties and is otherwise appropriate. 3907.2 A request to intervene shall be by motion stating the reasons why intervention should be permitted. 3907.3 While a proceeding is pending before the Rent Administrator, intervenors shall be considered full parties and shall have the same rights and duties as a party to a petition, with the following exceptions. (a) Intervenors shall not have an independent right to a hearing; and (b) Intervenors may participate only with respect to issues affecting them that do not require a hearing, as determined by the Rent Administrator.
Under D.C. Mun. Regs. tit. 14 et seq. § 14-3907, participation as an intervenor in Rental Accommodations Division proceedings is not guaranteed as a matter of right — it is discretionary and requires a formal motion explaining why intervention is appropriate. If permitted, an intervenor is treated as a full party while the matter is pending before the Rent Administrator, but with two key limitations: intervenors cannot independently demand a hearing, and their participation is confined to issues that affect them and do not require a hearing. The Rent Administrator determines the scope of any permitted intervention.
Plain English — not legal advice.
Property owners and managers involved in Rental Accommodations Division proceedings should be aware that under D.C. Mun. Regs. tit. 14 et seq. § 14-3907, third parties may seek to join a proceeding as intervenors by filing a motion before a hearing takes place. Compliant operators generally track whether any such motions have been filed, since an approved intervenor gains full-party status — including the ability to submit filings and respond to issues — within the limits set by the Rent Administrator. Understanding who has been permitted to intervene helps operators anticipate the scope of participation in a pending proceeding.

D.C. Mun. Regs. tit. 14 et seq. § 14-3907 establishes that tenants or other affected parties who are not original petitioners may seek to participate in a Rental Accommodations Division proceeding by filing a motion to intervene before a hearing is held. If the Rent Administrator grants the request, an intervenor is treated as a full party for most purposes, though they cannot independently trigger a hearing and may only weigh in on issues that directly affect them. Tenants who believe a pending proceeding affects their rights may wish to consult a tenant-rights organization or legal aid provider to understand whether seeking intervention status is an available path.
