According to the theory of premises liability, the owner of premises has a duty to his visitors, and thus can be held liable for injuries they sustain on the premises. If the owner is not the current occupant, the same may also apply to the tenant, or whomever else is the current occupant of the premises. Since the owner of premises has a duty of care to visitors, their breach of this duty when a visitor is injured constitutes negligence, which is the basis on which damages can be claimed. Similar to other forms of negligence, the premises liability follows the reasonable person standard, meaning that the owner or occupant should have taken action to ensure safety to visitors to the extent a reasonable person would. However, the standard of care is subjective — not only by the state in which premises liability takes place, but also depending on the activities that take place on the property and the type of visitor, who may be an invitee, licensee, or trespasser. For cases that reach the lawsuit status, the plaintiff may choose to consult a premises liability lawyer for legal assistance.
