Understanding Setback Requirements Before You Build
Setback requirements determine how close to your property boundaries you can build — and they affect far more construction projects than most people realise. Here’s what to understand before finalising your plans.
What Are Setbacks?
A setback is the minimum distance a structure must be positioned from a property boundary — front, side or rear — set out in planning regulations and, for residential properties, commonly guided by Victoria’s ResCode planning provisions alongside your specific council’s local planning scheme. Setbacks exist to manage amenity, privacy, access to light, and consistent streetscape character across a neighbourhood.
How Setbacks Are Determined
Setback requirements vary by boundary (front setbacks are often different to side and rear), property zoning, and sometimes the specific character of the local area or an existing neighbourhood pattern the council is trying to maintain. There isn’t a single universal figure that applies everywhere — your property’s specific zoning and local planning scheme determine the actual requirements that apply.
What Setback Requirements Affect
Setbacks most obviously affect building placement, but they can also influence retaining walls, structures like sheds and garages, and in some cases significant excavation or earthworks close to a boundary. Understanding your setback requirements early in project planning — before a slab or structure is designed — avoids the genuine problem of discovering a compliance issue after work has already begun.
Variations and Exemptions
Some structures may qualify for setback exemptions or reduced requirements depending on their size, height and specific circumstances, while others (particularly larger or more significant structures) may need a formal planning permit application, potentially including a setback variation request if the standard requirement can’t be met. These exemptions and variation processes are property and project-specific, not a general rule to assume applies.
Checking Your Property’s Requirements
The reliable way to confirm your property’s specific setback requirements is checking with your local council’s planning department, who can advise based on your property’s zoning and any relevant overlays. This is worth doing early in project planning, particularly for any structure or significant works planned close to a boundary, rather than discovering a setback issue partway through design or, worse, construction.

Frequently Asked Questions
Do setback rules apply to retaining walls?
They can, depending on the specific wall and its proximity to a boundary — worth checking alongside general retaining wall permit requirements for your project.
Are front and side setbacks the same?
Not usually — different setback requirements commonly apply to front, side and rear boundaries, set by your council’s planning scheme.
Can I get an exemption from setback requirements?
Sometimes, depending on the structure and circumstances, though this generally requires a formal planning process rather than being assumed.
Where do I find my property's specific setback requirements?
Your local council’s planning department is the reliable source, based on your property’s zoning and any relevant planning overlays.
Does a garden shed need to meet setback requirements?
It can, depending on size and location — some smaller structures may have specific exemptions, but this shouldn’t be assumed without checking.
