D.C. Mun. Regs. tit. 11, r. 11-734
Food delivery service shall be permitted in the C-2-A District if approved by the Board of Zoning Adjustment in accordance with the conditions specified in § 3104 for special exceptions, subject to the provisions of this section.
No part of the lot on which the use is located shall be within twenty-five feet (25 ft.) of a Residence District unless separated therefrom by a street or alley.
If any lot line of the lot abuts an alley containing a zone district boundary line for a Residence District, a continuous brick wall at least six feet (6 ft.) high and twelve inches (12 in.) thick shall be constructed and maintained on the lot along the length of that lot line. The brick wall shall not be required in the case of a building that extends for the full width of its lot.
Any refuse dumpster shall be housed in a three (3) sided brick enclosure equal in height to the dumpster or six feet (6 ft.) high, whichever is greater. The entrance to the enclosure shall include an opaque gate. The entrance shall not face a Residence District.
The use shall not include a drive-through.
The use shall be designed and operated so as not to become objectionable to neighboring properties because of noise, sounds, odors, lights, hours of operation, or other conditions.
The use shall provide sufficient off-street parking, but not less than that required by § 2101.1 to accommodate the needs of patrons and employees.
The use shall be located and designed so as to create no dangerous or otherwise objectionable traffic conditions.
The Board may impose conditions pertaining to design, screening, lighting, soundproofing, off-street parking spaces, signs, method and hours of trash collection, or any other matter necessary to protect adjacent or nearby property.
