In cases related to premises liability, premises owners are often held responsible for injuries that happen on their own properties. There are certain legal steps a premises owner or operator must take in warning others of any dangers located on the property, whether the other person has been invited, has chosen to enter the premises (as with a public business), or is trespassing. If a property owner is at all aware that another person has stepped foot on the premises, the owner is required by law to warn the visitor of any potentially unsafe conditions.
