Premises liability involves the responsibility of property owners to maintain safe conditions for people coming on or about the property. Homeowners can be and often are held liable for injuries which occur on their property. If a person slips, trips, or falls as a result of a dangerous or hazardous condition, the property owner may be fully responsible. Property owners are generally held accountable for falls as a result of water, ice, or snow, as well as abrupt changes in flooring, poor lighting, or a hidden hazard, such as a gap or hard to see hole in the ground. Several categories of persons to whom a property owner may be liable exist, and the duties of protection owed to each group are specific.
