It shall be the duty of the Code Enforcement Officer to enforce the provisions of this chapter. If, after investigation, the Code Enforcement Officer finds that any provision of this chapter is being violated, he or she shall give written notice delivered by hand, if the owner/occupant agrees to sign a receipt for the notice, or by certified mail, return receipt requested, to the person responsible for such violation, and/or to the owner and/or to the occupant of such premises.
