Violation procedure. When any violation of this chapter comes to the attention of the Code Enforcement Officer, a written notice of the violation to the owner of the premises shall be delivered. The notice may be served by having a copy of it delivered by certified mail, by handing a copy to the owner, or by leaving it at the owner's place of residence or usual place of business. If the owner cannot be found after a reasonably diligent search, the notice may be served by posting it in a conspicuous place on the premises in violation. The notice must state a specific, reasonable time within which the violation must cease. If the owner of the premises does not comply with the order within the specified time, the Code Enforcement Officer shall take appropriate legal action, consistent with this article and state statute.
