A. Imminent Danger. When, in the opinion of the code official, there is imminent danger of failure or collapse of a building or structure which endangers life, or when any structure or part of a structure has fallen and life is endangered by the occupation of the structure, or when there is actual or potential danger to the building occupants or those in the proximity of any structure because of explosives, explosive fumes or vapors or the presence of toxic fumes, gases or materials, or operation of defective or dangerous equipment, the code official is hereby authorized and empowered to order and require the occupants to vacate the premises forthwith. The code official shall cause to be posted at each entrance to such structure a notice reading as follows: "This Structure Is Unsafe and Its Occupancy Has Been Prohibited by the Code Official." It shall be unlawful and a misdemeanor for any person to enter such structure except for the purpose of securing the structure, making the required repairs, removing the hazardous condition or of demolishing the same.

B. Temporary Safeguards. Notwithstanding other provisions of this code, whenever, in the opinion of the code official, there is imminent danger due to an unsafe condition, the code official may order the necessary work to be done, including the boarding up of openings, to render such structure temporarily safe whether or not the legal procedure herein described has been instituted, and may cause such other action to be taken as the code official deems necessary to meet such emergency.

C. Closing Streets. When necessary for public safety, the code official may temporarily close structures and close, or order the authority having jurisdiction to close, sidewalks, streets, public ways and places adjacent to unsafe structures, and prohibit the same from being utilized.

D. Emergency Repairs. For the purpose of this section, the code official may employ the necessary labor and materials to perform the required work as expeditiously as possible.

E. Cost of Emergency Repairs. Costs incurred in the performance of emergency work shall initially be paid by the city. The city attorney may institute appropriate action against the owner of the premises where the unsafe structure is or was located for the recovery of such costs.

F. Hearing. Any person ordered to take emergency measures shall comply with such order forthwith. Any such person may appeal the determination that emergency procedures, as described in this section, were necessary or appropriate using the appeal procedures described in Section 1.14.070.
