D.C. Mun. Regs. tit. 10, r. 10-C325
An applicant may withdraw an application or may request a deferral of Board review by notifying the staff, in writing or otherwise, at any time.
If work has already been completed without the necessary permit, the staff may schedule the application for Board review regardless of a request for withdrawal. If scheduled for Board review, the staff shall inform the applicant of the time and place of the review in accordance with the procedures in this chapter.
An affected ANC may request a deferral of Board review of a case involving matters of significance to neighborhood planning and development, if the ANC has not received the requisite notice under the ANC Act (D.C. Official Code § 1-309.10) . The ANC shall make this request by notifying the staff in writing or by electronic mail, at least 48 hours before the scheduled Board meeting. The request shall state that the ANC has not had sufficient opportunity to hold a duly noticed public meeting to consider the application. Upon receipt of a written ANC request, the staff shall defer the case for a sufficient time to ensure that the ANC has received notice of forty-five (45) days.
A person or group directly affected by a case may request a one-month deferral of Board review for good cause, but shall bear the burden of demonstrating the need for a delay in view of the applicant's right to prompt consideration by the Board. The staff may require that this request be made in writing. The staff shall determine whether to defer the case, and may consult with the Chairperson of the Board in making this determination.
