At least thirty (30) days prior to the expiration of any security patrol service license or security patrol service employee permit, and upon any change in the officers, managing employees, stockholders or partners of a security patrol service, the licensee or permittee shall apply for renewal thereof. The application for renewal shall contain the same information as required for an initial application or, in the alternative, a statement of the particulars in which the information furnished with the initial application has changed. Upon such investigation as the chief of police deems proper, the license or permit shall be renewed if the city administrator finds that the applicant remains qualified as in the case of an original application. (Prior code § 8.345)
