The important distinction here is whether the plaintiff is a business invitee, such as a customer in a store, or merely a licensee, such as a social guest in someone's home. The store or other premises owner owes the duty to its business invitees to protect from unreasonably dangerous conditions or provide adequate warning of the danger. If the plaintiff is not a business invitee there is little or no responsibility.  For example, a pedestrian who is injured by an unreasonably dangerous hole in the sidewalk on the premises of a grocery store can recover damages if he or she intended to enter the store to shop, but not if only passing by. The landlord of an apartment complex can be held responsible for dangerous conditions in common areas used by more than one tenant, but normally not for conditions that exist inside the tenant's own apartment.
