It shall be unlawful for any person to violate the requirements of this chapter. In addition to the violator, there is a rebuttable presumption that an owner of a vehicle, building, yard, land, facility or equipment, is also responsible for violations of this chapter when the owner had or has actual or constructive knowledge of a violation at the time the violation occurred or is occurring. (Ord. M-3702 §3, 2005; Ord. M-3637 §1, 2003)
