Understanding the Retaining Wall Permit Process in Canberra


Navigating the permit process for retaining walls in Canberra involves specific steps and requirements. We explore below the different types of retaining walls, the permit application process, and the necessary documentation.


Identifying Your Retaining Wall Type


Retaining walls in Canberra are classified based on their height and purpose. Walls under 1 meter high typically don't require a permit, but it's always best to check with the local council.


Walls between 1-1.5 metres may need a permit depending on their location and structural complexity. Any wall over 1.5 meters high will require a Development Application and Building Approval.


Retaining walls supporting a driveway or near property boundaries often have additional requirements. We recommend consulting with a licensed builder or engineer to determine your wall's classification.


Steps to Acquiring a Retaining Wall Permit


  1. Initial Assessment: Evaluate your project's scope and determine if a permit is needed.
  2. Pre-Application Meeting: Schedule a consultation with the ACT Planning and Land Authority (ACTPLA) to discuss your plans.
  3. Prepare Documentation: Gather all required plans, drawings, and reports.
  4. Submit Application: Lodge your development application through the ACTPLA online portal.
  5. Review Process: ACTPLA will assess your application, which may take several weeks.
  6. Respond to Requests: Address any additional information requests promptly.
  7. Approval: Once approved, you'll receive a formal notice allowing construction to begin.


Required Documentation and Plans


To submit a successful retaining wall permit application in Canberra, you'll need to provide:

  • Site plan showing the wall's location, property boundaries, and existing structures
  • Detailed drawings of the retaining wall design, including dimensions and materials
  • Structural engineering calculations for walls over 1.5 metres high
  • Soil report if the wall is in a complex geological area


Additional documents may include:

  • Drainage plans to manage water runoff
  • Landscaping plans if the wall is part of a larger outdoor project
  • Neighbour consent forms if the wall affects adjoining properties


We recommend working with a professional draftsperson or engineer to ensure all plans meet ACTPLA standards. Accurate and comprehensive documentation can significantly speed up the approval process.


Navigating Regulations and Compliance


Building a retaining wall in Canberra requires careful adherence to local regulations and compliance standards. Below we guide you through the key aspects of navigating ACT regulations, inspection procedures, and maintaining ongoing compliance.


Complying with ACT Regulations


In Canberra, retaining walls over 1.5 metres in height require a Building Approval. We always check with the ACTPLA for the most up-to-date requirements. Structural drawings and calculations by a certified engineer are essential for the approval process.


For walls under 1.5 metres, a Development Application may still be necessary depending on factors like location and proximity to property boundaries. We recommend consulting with ACTPLA or a licensed builder to determine specific requirements for your project.


Soil testing and site analysis are often required to ensure the wall's stability and compliance with local soil conditions. We work closely with geotechnical experts to gather this crucial information.


Inspection and Approval Procedures


Once plans are submitted, ACTPLA reviews the application. This process typically takes 10-15 working days. During this time, additional information may be requested.


After approval, construction can begin. Inspections are conducted at key stages:

  1. Foundation preparation
  2. Drainage installation
  3. Reinforcement placement
  4. Final completion


We coordinate with inspectors to ensure timely visits and smooth progress. Any issues identified during inspections are promptly addressed to maintain compliance and avoid delays.


Maintaining Compliance Post-Approval


After construction, ongoing maintenance is crucial for long-term compliance. We provide clients with a detailed maintenance plan outlining regular checks and upkeep procedures.


Key maintenance tasks include:

  • Inspecting drainage systems
  • Checking for signs of movement or cracking
  • Ensuring proper water runoff
  • Monitoring nearby vegetation


We recommend annual professional inspections to catch potential issues early. Keeping detailed records of maintenance and any repairs helps demonstrate ongoing compliance if questions arise in the future.


For significant changes or repairs to an existing retaining wall, new approvals may be required. We advise clients to consult with ACTPLA before undertaking major modifications to ensure continued compliance with current regulations.
