private nuisance

Definition from Nolo’s Plain-English Law Dictionary

An activity or thing that interferes with the use of property by an individual (or a few individuals) by being irritating, offensive, or obstructive. Nuisances can include everything from noise and illegal gambling to posting indecent signs and misdirecting water on to other property. Conditions that affect an entire community are a public nuisance. Lawsuits may be brought to abate (remove or reduce) a nuisance.
