D.C. Mun. Regs. tit. 23, r. 23-404
No license, except a Solicitor's license, Manager's license, or Caterer's license shall be issued to any person unless that person is the holder of a valid certificate of occupancy for the premises in which the business for which the license is sought is located, and is also the holder of all other licenses and permits required by law or regulation for that business.
If a certificate of occupancy has been obtained, and the applicant for the alcoholic beverage license has duly applied for all other licenses and permits required by law or regulation for that business, the Board may, in its discretion but subject to all other requirements of this chapter, issue the alcoholic beverage license prior to the issuance of those other licenses and permits.
The provisions of §§ 404.1 and 404.2 shall not apply to applications for Temporary licenses Class F or G, as long as the alcoholic beverages are sold and served in establishments that have a valid certificate of occupancy, and as long as the applicant for the license provides the Board with a statement from the owner of the establishment or the owner's duly authorized representative, consenting to the issuance of the license. A certificate of occupancy shall not be required for outdoor events or private residential homes used for non-commercial purposes. However, if alcoholic beverages are to be sold or served in any outdoor place (including but not limited to public parks, public streets or alleys), the application for the license shall particularly describe the place and the applicant shall provide the Board with a written statement indicating the owner's consent, or applicable public approval, if required.
