Emergency action. If, in the opinion of the Building and Zoning Administrator, a violation exists which requires immediate action to avoid a direct hazard or imminent danger to the health, safety, morals or welfare of occupants of a building or to other persons, the Building and Zoning Administrator may direct such violation immediately remedied or may take direct action on his own initiative to abate the hazard or danger. Any costs incurred by such action shall be paid for by the owner, occupant or person responsible for the violation. The Building and Zoning Administrator shall keep on file an affidavit stating with fairness and accuracy the items of expense and date of execution of action taken, and is furthermore authorized to institute a suit, if necessary, against the person liable for such expenses, or place a lien against property, in order to recover said costs.
