Property owners are legally obligated to keep their property reasonably safe and hazard-free. The owner of the property in which a slip or trip and fall occurs is normally responsible only if the dangerous condition causing the fall was known or should have been known to him/her and the owner failed to warn about it or fix the danger (unless it is a danger that is “open and obvious”). Owners can also be liable, even if they are unaware of the specific hazard, if they do not monitor the changing condition of the property.
