Building a backyard shed is usually a straightforward process. In some cases, you may not need a development approval. Sheds that don’t need approval must still follow building legislation and codes.
There are three factors that determine if you need approval:
- shed size
- shed location
- shed structure.
If your property is Heritage-listed or in a Neighbourhood Character Area, there may be other requirements. For more information, see the Register of Heritage and Neighbourhood Character Places.
Shed size
You don’t need a building approval for the shed if the following applies:
- area is less than 10m2
- mean height of a wall on a boundary is less than 2.1m
- overall height is no more than 2.4m
- side is no longer than 5m.
To calculate the mean height, divide the total area of the wall by the horizontal length of the wall.
If your shed doesn’t meet this criteria, you need to apply for a building approval. A licenced building certifier can help you lodge this application to us.
Shed location
Siting and setbacks
The location of the shed on your property must be in line with the siting and setback requirements of the Queensland Development Code (QDC). There are different requirements for lots under and over 450m2.
In some instances, the Toowoomba Regional Planning Scheme (the Planning Scheme) may provide alternative building requirements. These can include:
- different setbacks for outbuildings in a Rural Zone
- alternative site coverage requirements in a Rural Residential Zone.
If you can’t meet the setback requirements, you need to apply for a siting discretion. You also need building approval.
For more information, see Building near a boundary.
Near or over Council infrastructure
Your shed must be clear of Council infrastructure. This includes water, sewer or stormwater services.
Use our online mapping service to check for underground services running through your property. Call us on 131 872 and ask for the:
- house drainage plan (for a fee)
- land application area, where applicable.
These can help determine the exact location of services.
If the proposed shed is over or near infrastructure, you must submit a plumbing application.
To find out more about these requirements, see QDC mandatory part (MP) 1.4.
Shed structure
You need to ensure the shed meets the structural requirements of the Building Code of Australia (BCA). These include:
- structural adequacy
- fire separation
- general health and amenity.
Your shed must be in line with all relevant codes and standards, even if you don’t need a building approval.
Talk to a licenced building certifier if you have any questions about the BCA requirements.
