Tenement most often is used to refer to property involved in an easement. The property benefiting from the easement is called the dominant tenement, and the property granting the easement is called the servient tenement.
Tenement also is an outdated term referring to permanent buildings or structures on a piece of property including other rights besides ownership, such as the ability to lease the property. The term originates from the middle ages where the term referred to property controlled by individuals, but under feudal systems, all of the land was actually owned by the crown or lords.
