D.C. Mun. Regs. tit. 18, r. 18-908
No license shall be issued, nor shall any renewal of a license be made, for conducting a drivers' school unless the school has a designated place of business in the District, or complies with the provisions of § 907.3.
For the purposes of this chapter, "place of business" means a designated location at which the business of a drivers' school is transacted and its records kept.
A driving school license or renewal may be issued to an applicant which has its principal place of business outside of the District upon the filing by the applicant with the Director, Department of Consumer and Regulatory Affairs, a written statement designating a resident agent in the District for the service of process, and of any notice, order, or rule to show cause issued by the Director, Department of Consumer and Regulatory Affairs, or any other officer or department of the District, in connection with any proceedings arising out of the conduct of the driving school business in the District.
A copy of any notice, order, or rule to show cause served upon a designated agent of a driving school shall be sent by registered mail to the licensee at its principal designated place of business.
Each licensee shall keep such records as the Director, Department of Consumer and Regulatory Affairs may require. The records of the licensee shall be open to inspection by the Director, or his or her-designee, and the Chief of Police, or his or her representative, at all times during reasonable business hours.
