No permit may be issued for the sale of alcoholic liquor in any building, a portion of which will not be used as the permit premises, unless the application therefor is accompanied by an affidavit signed and affirmed by the applicant, stating that access from the portion of the building that will not be used as the permit premises to the portion of the building that will be used as the permit premises is effectually closed, unless the Department of Consumer Protection endorses upon such application that it has dispensed with such affidavit for reasons considered by it good and satisfactory and also endorses thereon such reasons. If any way of access from the other portion of such building to the portion used as the permit premises is opened, after such permit is issued, without the consent of the Department of Consumer Protection endorsed on such permit, such permit shall thereupon become and be forfeited, with or without notice from the Department of Consumer Protection, and shall be null and void. If such applicant or any permittee or any backer thereof opens, causes to be opened, permits to be opened or allows to remain open, at any time during the term for which such permit is issued, any way of access from any portion of a building not part of the permit premises to any other portion of such building that is the permit premises, without the written consent of the Department of Consumer Protection endorsed on such permit, such persons or backers shall be subject to the penalties provided in section 30-113. The Department of Consumer Protection shall require every applicant for a permit to sell alcoholic liquor to state under oath whether any portion of the building in which it is proposed to carry on such business will not be used as the permit premises; and, if so, the Department of Consumer Protection shall appoint a suitable person to examine the premises and to see that any and all access between the portion so to be used for the sale of alcoholic liquor and the portion not so used is effectually closed, and may designate the manner of such closing, and, if necessary, order seals to be placed so that such way of access cannot be opened without breaking the seals, and the breaking or removal of such seals or other methods of preventing access, so ordered and provided, shall be prima facie evidence of a violation of this section. The above provisions shall not apply to any premises operating under a hotel permit.
