A property owner has a nondelegable duty to maintain its premises in a reasonably safe condition, taking into account the forseeability of injury to others. Even if a hazard is discernible, the owner may be liable. A plaintiff's awareness of a dangerous condition does not negate a duty to warn of the hazard, but only goes to the issue of comparative negligence.
