When in the opinion of the enforcing officer, any structure is in such condition as to constitute an immediate hazard requiring immediate action to protect the public, such officer may erect barricades or cause the property to be vacated, taken down, repaired, shored or otherwise made safe without delay and such action may, under such circumstances, be taken without prior notice to or hearing of the owner's agents, lienholders and occupants. The cost of any such action shall be assessed against the property and paid in the manner provided by Section 15.16.070 of this chapter. (Prior code § 5-708)
