All licenses issued shall be subject to renewal upon a showing of compliance with §§ 5-202 and 5-203 within a six-month-period prior to the renewal date. The City Clerk need not require an additional application under § 5-203 or an additional investigation and investigation fee under §§ 5-205 and 5-206 unless complaints have been received of violations of the conditions in which any license has heretofore been issued. The City Clerk shall not renew or extend any license if there is satisfactory evidence of any grounds for the suspension or revocation of any prior license, and the applicant shall be required to apply for a license as in the case of an original license.
