These types of wall are covered

1. Party Wall A wall that divides the buildings of two or more owners with the boundary between different ownerships, usually but not always, positioned parallel to, and at the centre of the wall. However, the Act differentiates between two specific types and these are referred to as Type A and B.

Type A Wall: A wall which forms part of a building and stands on lands of different owners to a greater extent than the projection of any artificially formed support on which the wall rests. Examples include a typical terrace property divided by a solid masonry wall.

Type B Wall: A wall that stands wholly on one owner’s land, but is used by two (or more) owners to separate their buildings. Examples include where one Adjoining Owner has a structure that leans against a wall that is owned by the other Adjoining Owner. Only the part of the wall that is enclosed by the lean-to is a Party Wall.

2. Party Fence Wall A wall (not being part of a building) which stands on lands of different owners and is used or constructed to be used for separating such adjoining lands, typically referred to as a garden or boundary wall. This does not include a wall constructed on the land of one owner the artificially formed support of which projects into the land of another owner. Wooden fences, or even fences with concrete posts, are not party fence walls.

3. Party Structure Any party wall, floor partition, or other structure separating buildings or parts of buildings approached solely by separate staircases or separate entrances.
