Check whether the wall is adequately set back from boundaries

Refer to the site plan to assess the position of the wall in relation to boundaries.

Walls supporting excavation that are over 400mm in height must be set back from the boundaries the same distance as the height of the wall (1:1 ratio).

For example, if the wall is 600mm high, it needs to be placed at least 600mm away from any property boundaries.

 

Does your retaining wall meet the setback requirements for walls that support excavation?

  • If yes, you do not need a Building Permit. As long as there are no planning restrictions, you can proceed to construct the wall. You may exit this guide.
  • If no, apply for a Building Permit.
