What is an Unreasonably Dangerous Property Condition?

Property owners are responsible for injuries that occur as a result of a dangerous or hazardous condition on their property, which the owner knew about, or should have known about. The hazard may be obvious (such as a broken stair) or hidden (like a hole in a lawn that is partially covered by grass). In some instances it may not be apparent, as in flooring which appears normal, but is slippery. It could be permanent, like broken concrete with a change in elevation, or temporary, like a liquid spill in a supermarket aisle. In general, an owner will be considered to have knowledge of a dangerous or hazardous condition if it is permanent in nature, since the owner knew, or should have known, about the condition before the incident occurs. In the case of temporary conditions (like a liquid spill), the length of time that the condition existed before the incident occurred has legal significance.
