Excavation work in Victoria typically requires official authorization. Depending on the project’s complexity, homeowners may need both planning and building permits to ensure compliance with state and local regulations.
Planning Permits
A planning permit is required when excavation changes the natural landform, affects land use, or is within a heritage or environmentally sensitive area. These permits assess how the excavation fits into broader land-use strategies.
Building Permits
A building permit is mandatory when excavation work is related to a construction project. This includes site cuts for foundations, retaining walls, basements, or other structural elements. Building permits ensure all excavation complies with safety and engineering standards.
Application Process
Homeowners must follow a structured process to apply for the required permits.
- Confirm Permit Requirements
Contact your local council to determine whether a planning permit is required. Not all projects need both types, but early clarification is essential. - Engage a Building Surveyor
A registered building surveyor is required to review technical plans and oversee compliance throughout the excavation process. Homeowners can choose either a private or municipal surveyor. - Prepare Documentation
Documents typically include a site plan, engineering assessments, and any necessary planning permits. Complete and accurate information reduces the risk of application delays. - Submit Applications
Planning permit applications go to the local council. Once planning approval is secured (if needed), the building permit application is submitted through the building surveyor. - Approval and Commencement
Excavation work can begin only after receiving formal approval. The building permit specifies the scope and conditions of the work.
Safety Compliance
Strict safety obligations apply during excavation activities. Failure to meet them can result in penalties or serious accidents.
- Work Notifications
Projects involving trenches deeper than 1.5 meters or shafts deeper than two meters must be reported to WorkSafe at least three business days before work starts. - Underground Utility Checks
Homeowners must identify the location of underground infrastructure before digging. This prevents potential hazards such as damaging gas, water, or electrical lines. - Site Protection Measures
Depending on the depth and location, safety systems such as trench shields, shoring, or sloping may be required to prevent collapse and injury.
Owner-Builder
Homeowners acting as their own builder must meet additional compliance and certification standards.
- Certificate of Consent
A Certificate of Consent is required for owner-builders if the total value of the project, including excavation, exceeds $16,000. - Mandatory Insurance
Domestic building insurance is required to cover structural defects or contractor insolvency. This protects both the owner and future buyers. - Regulatory Responsibility
Owner-builders carry full legal responsibility for meeting building standards and permit conditions, including those specific to excavation.
Homeowners planning excavation work in Victoria must assess the need for planning and building permits, follow the correct application processes, and adhere to safety and legal standards. For those acting as owner-builders, additional obligations apply. Early consultation with professionals and regulatory bodies ensures that the project proceeds safely, legally, and without interruption.
