The duty of care a property owner is obligated to provide a visitor depends on the relationship between the visitor and the property owner. Legally, people visiting any property at any point in time are categorized as either invitees, licensees, or trespassers.
Invitees received either an expressed or implied invitation from the property owner to enter, and thus, are owed a high duty of care. Licensees are authorized to be on the property, and so a property owner must warn them of any dangerous conditions. Lastly, trespassers do not have permission to be on the property and are not owed a duty of care by the property owner.
