Do you need Council Approval?
Short answer: it depends. Your state, local council, block size, zoning, and your shed’s size and placement all play a role.
There isn’t a single national rule for backyard sheds in Australia, which is why council approval is one of the most common questions we hear before a customer buys a shed.
This guide explains how shed approval requirements generally work across Australia and what typically qualifies a shed for exempt development, meaning no development application is required.
Disclaimer: This article provides general information only and should not be considered legal, planning, or building advice. Rules vary between councils and can change over time. Always confirm requirements with your local council or relevant planning authority before building.
What Does “Exempt Development” Mean?
Most Australian states use a category known as exempt development for low-impact structures.
If your shed is a non-habitable Class 10a building under the National Construction Code (the same category used for garages and carports) and meets specific requirements relating to size, height and setbacks, you can often build it without lodging a Development Application (DA).
If the shed doesn’t meet those requirements, you’ll generally need either:
- A Complying Development Certificate (CDC) or equivalent streamlined approval process
- A full Development Application through your local council
Backyard Shed Approval Rules by State
New South Wales
Many residential properties can accommodate sheds of up to 20m² as exempt development, with allowances of up to 50m² in some rural zones.
Typical requirements include:
- Located behind the building line
- At least 900mm from boundaries
- Maximum height of around 3 metres
Rules are governed by the State Environmental Planning Policy (Exempt and Complying Development Codes).
Victoria
A building permit is generally required when a shed:
- Exceeds approximately 10m²
- Is higher than 3 metres
- Is attached to another structure
Smaller freestanding sheds may not require a permit, although planning overlays such as heritage, bushfire and flood controls can still apply.
Queensland
Approval is commonly required when a shed:
- Exceeds approximately 10m²
- Is taller than 2.4 metres
- Is positioned within 1.5 metres of a boundary
Smaller garden sheds that meet these limits are often exempt.
South Australia
Sheds are commonly exempt when they:
- Are no larger than approximately 15m²
- Have a roof span under 3 metres
- Do not exceed 2.5 metres in height
- Are at least 900mm from boundaries
- Sit behind the front building line
Western Australia, Tasmania and the Northern Territory
Requirements vary considerably between councils.
As a general rule, sheds under approximately 10m² that meet local setback and height requirements may be exempt. Always check with your local authority before construction.
Australian Capital Territory (ACT)
Approval thresholds are linked to block size and can range from approximately 10m² to 50m² depending on the property.
Height limits and boundary setbacks also apply.
Common Requirements for Exempt Development
Regardless of which state you’re in, most exempt development pathways share similar conditions:
- Size limits ranging from approximately 10m² to 20m² in residential zones
- Height limits typically between 2.4m and 3m
- Boundary setbacks, often around 900mm from fences and property lines
- Non-habitable use only, such as storage, gardening equipment or workshops
- No planning constraints, including heritage overlays, bushfire-prone areas, flood zones, easements or other site restrictions
Even if your shed meets size requirements, these site-specific factors can still trigger approval requirements.
Where Does This Leave a Trekk Shed?
Most of the Trekk shed range has been designed with compact backyard installations in mind.
Several models feature footprints under 9m², which places them comfortably within the exempt development thresholds commonly found across many Australian council areas.
However, council regulations ultimately depend on your individual property, zoning and local planning controls. It’s always worth confirming requirements before purchasing rather than after installation.
What Happens If You Build Without Required Approval?
Building a shed without appropriate approval can lead to:
- Council fines
- Stop-work orders
- Retrospective approval costs
- Expensive modifications
- Removal orders for non-compliant structures
In some situations, insurers may also decline claims relating to unapproved structures.
A quick check with your local council before construction can save significant time, money and frustration later.
Frequently Asked Questions
Does a small garden shed always need council approval?
Not necessarily. Many councils provide exemptions for small sheds that meet specific size, height and setback requirements. Eligibility depends on your property’s zoning and local planning controls.
What’s the easiest way to check if my shed is exempt?
Visit your local council website and search for “shed approval”, “outbuildings” or “exempt development”. Many states also provide online planning portals where property requirements can be checked by address.
Does shed material affect approval requirements?
Generally no. Approval requirements are usually determined by size, height, location and intended use.
However, bushfire-prone areas and certain planning overlays may require specific construction materials.
Who should I contact if I’m unsure?
Your local council’s planning department is usually the best first point of contact. For more complex sites involving bushfire overlays, heritage controls or easements, a private certifier or planning consultant can help.
