Building a Granny Flat in Brisbane City Council: Secondary Dwellings

Building a granny flat in Brisbane, also known as a secondary dwelling, offers a great way to add extra living space to your property. Whether it’s for accommodating family members, generating rental income, or increasing property value, understanding the approval process and regulations is crucial. Here’s a comprehensive guide to help you navigate the requirements set by the Brisbane City Council.

Granny Flat Approval

Building A Granny Flat In Brisbane without planning approval is now allowed as long as you follow the requirements in the Brisbane Town Plan.

Building Applications

In Brisbane, a secondary dwelling can be built without planning approval if it meets specific criteria outlined in the Brisbane City Plan 2014. The key requirements include:

Size: The granny flat must be a maximum of 80 square metres in size.
Proximity: It must be located within 20 metres of the main dwelling ¹.

If your proposed granny flat exceeds these limits, you will need to lodge a development application with the Council ¹. Additionally, all building work must be approved by a private certifier before construction begins ¹.

Zones, Overlays, and Local Area Plans

The Brisbane City Plan 2014 includes various zones, overlays, and local area plans that can affect your property. These elements are crucial in determining what you can build and where:

Zones: Zones dictate the types of buildings and activities allowed in an area. Residential zones are typically where granny flats are permitted ¹.
Overlays: Overlays highlight specific characteristics of a property, such as flood risk, biodiversity, or heritage value. These can impose additional requirements or restrictions on your development ².
Local Area Plans: These plans provide detailed guidelines for development in specific areas, ensuring that new buildings align with the local character and planning objectives ³.

You can use the City Plan online mapping tool to check the zones, overlays, and local area plans applicable to your property ³.

Secondary Dwelling Boundary Setbacks

Boundary setbacks are essential for maintaining privacy, amenity, and property maintenance. The Queensland Development Code (QDC) sets the boundary setbacks for secondary dwellings:

These setbacks ensure that the secondary dwelling is appropriately distanced from property boundaries, protecting the privacy and amenity of both the primary and secondary dwellings ⁴.

Maximum Site Cover

The maximum site cover refers to the portion of your property that can be covered by buildings. In Brisbane, the site cover limits are as follows:

These limits ensure that there is sufficient open space on the property for landscaping, recreation, and stormwater management ⁵.

Conclusion

Building a granny flat in Brisbane requires careful planning and adherence to the Brisbane City Plan 2014. By understanding the approval process, zoning regulations, boundary setbacks, and site cover limits, you can ensure a smooth and compliant construction process. For more detailed information, you can refer to the Brisbane City Council’s official guidelines.
