What is a party wall?
The main types of party walls are:
- A wall that stands on the lands of 2 (or more) owners and forms part of a building – this wall can be part of one building only or separate buildings belonging to different owners
- A wall that stands on the lands of 2 owners but does not form part of a building, such as a garden wall but not including timber fences
- A wall that is on one owner’s land but is used by 2 (or more) owners to separate their buildings
The Act also uses the expression ‘party structure’. This could be a wall or floor partition or other structure separating buildings or parts of buildings in different ownership, such as in flats.
