In law, an act, object, or practice that interferes with another's rights or interests by being offensive, annoying, dangerous, obstructive, or unhealthful.
Such activities as obstructing a public road, polluting air and water, operating a house of prostitution, or keeping explosives are public nuisances and constitute criminal violations. A private nuisance is an activity or condition (e.g., excessive noise, disagreeable odor) that interferes with the use and enjoyment of one's property and that may be a cause of action in civil litigation. An attractive nuisance is something on one's property that poses a risk to children or others who may be attracted to it.
