(1) Except as provided in subsection (2) of this section, if the existence of the nuisance is established in the action, an order of abatement shall be entered as part of the final judgment in the case. Plaintiff‘s costs in the action, including those of abatement, are a lien upon the building or unit within a building. The lien is enforceable and collectible by execution issued by order of the court.

(2) If the court finds and concludes that the owner of the building or unit within a building: (a) Had no knowledge of the existence of the nuisance or has been making reasonable efforts to abate the nuisance, (b) has not been guilty of any contempt of court in the proceedings, and (c) will immediately abate any such nuisance that may exist at the building or unit within a building and prevent it from being a nuisance within a period of one year thereafter, the court shall, if satisfied of the owner’s good faith, order the building or unit within a building to be delivered to the owner, and no order of abatement shall be entered. If an order of abatement has been entered and the owner subsequently meets the requirements of this subsection, the order of abatement shall be canceled.
