The Hills Shire Council – Retaining Wall Approvals & Contact Details
If you’re building a retaining wall in the Hills District, approval requirements will depend on the wall’s height, location, drainage, and proximity to boundaries. In some cases, retaining walls may qualify as exempt development, while others will require a Development Application (DA) or Complying Development Certificate (CDC).
Before starting construction, it’s always best to confirm requirements directly with council.
