When payment of a renewal fee is prescribed, licenses and certificates of registration and renewals thereof shall expire on December 31 of each year and may be renewed during the thirty-day period immediately preceding the expiration date upon payment of the prescribed renewal fee, provided that no license or certificate of registration which has been revoked shall be renewed, and no certificate of registration shall be renewed when there is on record uncorrected violations of this Code, charged to the holder of such certificate.
Licenses and certificates of registration shall not be transferable, provided, however, that with the consent of the Commissioner of Buildings, the names of new members or officers of a firm, copartnership, corporation or association holding a certificate of registration may be substituted for, or added to, those previously on record.
