Whenever necessary to make an inspection to enforce any of the provisions of this chapter, or whenever the chief or his authorized representative has reasonable cause to believe that there exists in any building or upon any premises any condition which makes such building or premises unsafe, the chief or his authorized representative may enter such building or premises at all reasonable times to inspect the same or to perform any duty imposed upon the chief by this chapter, provided that if such building or premises is occupied, he shall first present proper credentials and demand entry; and if such building or premises is unoccupied, he shall first make a reasonable effort to locate the owner or other persons having charge or control of the building or premises and demand entry. If such entry is refused, the chief or his authorized representative shall have recourse to every remedy provided by law to secure entry. (Ord. 125 §1, amended; Prior code §7-13)
