(a) The registered owner of the unit, or any other cited person or entity that fails to correct a violation or abate a nuisance within the time allotted in the original correction order, or any extension thereto, shall be held responsible for the costs of abatement of the violation. Costs of abatement, for purposes of this section, may include the enforcement agency's investigative and case preparation costs, court costs and attorney fees, the cost associated with any physical actions taken to abate the violation, and any technical service or other fees due to the enforcement agency related to the abatement activity.

(b) If the unit is in such condition that identification numbers are not available to determine ownership, or the enforcement agency is unable to locate the owner after making a reasonable effort to do so, the owner of the property on which the unit is located shall be liable for such costs.
