City officers shall have the right to enter, with proper warrant, upon private premises for the purpose specified in Section 1121.05, upon compliance with all applicable provisions of law. Unless it appears probable that advance warning would defeat the purpose of such entry, occupants of premises to be entered shall be given reasonable notice in advance, and in any case no owner or occupant shall prevent such entry which is sought to be made in compliance with law.
