Navigating Brisbane’s Building Regulations for Renovations and Extensions
Planning a home renovation or extension in Brisbane?
Before you start knocking down walls or adding new rooms, it’s important to understand the building regulations that apply. Getting it wrong can lead to costly delays or even fines.
Here’s what you need to know.
What permission do I need to build an extension?
In most cases, you’ll need building approval to construct an extension. This approval ensures your plans comply with:
-
The Queensland Building Code
-
Local council zoning and planning rules
-
Structural and safety standards
You may also need planning approval from Brisbane City Council if your extension changes the building’s footprint, height, or street appearance. Extensions that are near property boundaries or affect neighbours may trigger further assessments.
The safest first step? Speak with a private building certifier or a builder experienced in Brisbane projects.
Do I need council approval for internal renovations in QLD?
If you’re renovating the interior of your home — such as updating the kitchen, knocking down non-load bearing walls, or reconfiguring rooms — council approval is not always needed.
You don’t need council approval if:
-
You’re not making structural changes
-
You’re not increasing the building’s floor area
-
The work doesn’t affect plumbing, fire safety, or load-bearing walls
However, if your internal renovation involves any structural changes or affects building services (e.g. plumbing or electrical systems), building approval may be required.
Still unsure? A quick call to your local certifier or council can clear it up fast.
What can I build without council approval in QLD?
You can build certain small-scale projects without council approval, known as self-assessable development. These include:
-
Small garden sheds (under 10m²)
-
Low decks (less than 1m high)
-
Fences (under 2m high)
-
Pergolas or shade structures (within certain size limits)
That said, there are still rules on where these can be placed on your block and how big they can be. So while approval might not be required, compliance is still essential.
