Check the distance of the wall from other structures

A wall that supports excavation must be more than 400mm away from other structures and buildings.

 

Is the wall more than 400mm away from other structures?

  • 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 can now exit this guide.
  • If no, you need to consult a registered building surveyor for advice: 
    • If the surveyor advises that the wall is too close to other structures, apply for a Building Permit.
    • If the surveyor advises that the distance is adequate, and there are no planning restrictions, you may exit the guide and proceed with construction.
