PLANNING A NEW BUILDING FOR YOUR BACKYARD?

Does it need council approval?

Imagine having your perfect garden building, shed, or carport set up sooner, without navigating complex council applications. The good news is, for many non-habitable structures across Australia, you might not need council approval!

While rules vary in every state and territory, most councils allow smaller, non-habitable buildings (like Class 10a sheds, carports, and private garages) to be installed without formal approval, provided they meet specific conditions. This can mean a faster, more straightforward path to enjoying your new space.

Understanding the building approval landscape can seem complex, as each state and territory operates under its own unique set of requirements and exemptions.

As a general guideline, many councils throughout Australia permit the installation of non-habitable structures (such as Class 10a buildings – including sheds, carports, and private garages) without requiring full development approval, provided they adhere to specific conditions.

These conditions often relate to:

  • Size Allowances: Maximum floor area and height limits.
  • Proximity to Boundaries: Setback requirements from property lines.
  • Building Materials: Restrictions on certain materials.
  • Property Type: Differing rules for rural vs. urban properties.
  • Bushfire or Flood Zones: Additional considerations in hazard-prone areas.

We’ve been helping customers like you find the right buildings for exempt development purposes for almost 50 years. Our experience means we can help you navigate exempt requirements and whether you’ll need approval.

Remember: This is a general guide. We always recommend you also speak to your local council to determine whether your individual project requires any permits or approvals. It’s also highly recommended that you discuss your proposed development with your neighbours, regardless of whether you need approval or not.

The BCA (Building Code of Australia) notes a Class 10a Building as a non-habitable building including sheds, carports, and private garages.
