Council Requirements for Excavation and Earthworks in Melbourne
Excavation and earthworks in Melbourne can trigger a range of council and regulatory requirements beyond a standard building permit. Here’s what’s typically involved and why it pays to check early.
When Council Involvement Is Required
Excavation and earthworks can trigger council involvement in several ways: as part of a broader building or planning permit application, through specific local laws governing excavation near boundaries or public land, or through drainage and stormwater approval requirements. Not every excavation project needs separate council sign-off beyond a standard building permit, but assuming that’s always the case is a common and sometimes costly mistake.
Drainage and Stormwater Requirements
Changes to a site’s grading and drainage from excavation work can affect how stormwater moves across and off the property, including onto neighbouring land — councils generally have requirements around managing this, particularly for larger excavation or bulk earthworks projects. Getting stormwater and drainage design right isn’t just a compliance box to tick, either — poor drainage planning is one of the most common causes of disputes with neighbours and ongoing site problems after work is complete.
Boundary and Support of Adjoining Land
Excavation near a property boundary carries specific legal obligations around supporting adjoining land and structures — undermining a neighbour’s fence, retaining wall or building through excavation work is a real liability, not just a courtesy issue. Depending on depth and proximity, this can require specific engineering, notification of adjoining owners, or additional support measures during the works.
Heritage and Other Planning Overlays
Some Melbourne properties sit within heritage overlays, vegetation protection overlays, or other planning controls that add requirements specific to excavation and earthworks — anything from archaeological considerations in heritage areas through to tree protection zones limiting excavation near significant vegetation. Checking your property’s specific planning overlays before finalising an excavation scope avoids an unwelcome surprise mid-project.
Dial Before You Dig
Before any excavation begins, checking for underground services (gas, water, electricity, telecommunications) via Dial Before You Dig is a legal requirement in Victoria, not an optional precaution. Striking a service during excavation is a genuine safety risk and can result in significant cost and disruption — this is one of the most basic and non-negotiable steps in any compliant excavation project.
Checking Before You Start
Because requirements vary by council, property and project scope, the most reliable approach is to check directly with your local council and a building surveyor about what applies to your specific site before excavation begins. We factor this into our project planning process and can help identify what’s likely to apply based on your site and scope, though final confirmation always sits with the relevant authority for your property.

Frequently Asked Questions
Does every excavation project need council approval?
Not necessarily beyond a standard building permit, but it depends on the project scope, site location and any specific overlays — it’s worth checking rather than assuming.
Is Dial Before You Dig legally required?
Yes — checking for underground services before excavation is a legal requirement in Victoria and a basic safety step on every project.
What happens if excavation affects a neighbour's property?
There are legal obligations around supporting adjoining land during excavation near a boundary — this can require specific engineering or notification depending on depth and proximity.
How do I find out if my property has a planning overlay?
Your local council’s planning department or an online planning property report can confirm what overlays, if any, apply to your specific property.
Does stormwater drainage need council approval for earthworks?
It can, particularly for larger projects that change site grading significantly — this is worth confirming with council as part of project planning.
