Notwithstanding any other provision of this code, whenever, in the reasonable judgment of the enforcement officer, the existence or continuance of any violation of this code or any nuisance condition poses an imminent or immediate threat of harm to persons or property, or to public health, welfare or safety, an enforcement officer may act immediately and without prior notice or hearing to abate such violation or condition. The expense or cost resulting from such summary abatement shall be enforceable as a personal obligation of the responsible party and may be imposed as a lien or a special assessment on real property, as described in Section 1.14.160 of this code. (Ord. 651 § 2 (part), 2005)
