Which concept describes unreasonable use of property to interfere with another's land?

The concept that describes unreasonable use of property to interfere with another's land is private nuisance. Private nuisance refers specifically to instances where a person's use of their property substantially interferes with another individual's use and enjoyment of their own land. This can include various activities such as loud noise, unpleasant odors, or anything that would disrupt the normal experience of neighboring property owners.

In contrast, public nuisance involves activities that impact the community at large, rather than just a single individual or a select few. An artisan's lien is a legal claim against property for unpaid services or materials provided, which does not relate to the interference aspect. Encroachment occurs when a property owner builds or extends a structure onto a neighboring property without permission, but it does not necessarily involve the unreasonable use of property as defined in private nuisance. Therefore, the definition of private nuisance aligns precisely with the concept of unreasonable use of property impacting another's land.
