Appurtenance

The term ‘appurtenance’ denotes a subordinate yet essential component or attachment to a larger entity. In the context of buildings, property, and land, it signifies something that is legally part of another more substantial and valuable entity. Its interpretation encompasses various elements, ranging from structures like barns, driveways, and fences to fixtures such as parapets, aerials, and solar panels.

Essentially, an appurtenance refers to any attachment that, once installed or affixed, becomes inseparable from its larger entity. Consequently, it appears in legal clauses pertaining to rental properties as well as in those concerning land and property sales.

In the realm of building construction, the term extends to ancillary or complementary components associated with plumbing, electrical, gas, or servicing equipment essential for the operation of a building.

According to the HM Land Registry’s 1862 Act Register, appurtenance is defined as “property that belongs to something else, such as a shed, barn, or garden grounds of a building.”
