Do I need council approval for a carport?
Written and verified by Struqt’s registered architects · Last verified July 2026
In most places a carport needs some form of approval, and it's often less about size and more about where you put it. A carport tucked beside or behind your house and open on the sides has the best shot at an easy approval.

Key takeaway: Carports are treated more strictly than sheds because of where they go, not what they are — they so often sit forward of the building line and near a street boundary that they trip setback and streetscape rules a backyard shed never touches.
Carport approval, state by state
Do I need approval for a carport in NSW?
An open carport up to 20m² (or 25m² on a block over 300m²), under 3m high, sitting behind the front of your house, can usually be built with no approval at all — provided it stays open on at least two sides — a third or more of its perimeter — and sits at least a metre behind the building line. Bring it forward of the house, or close it in, and you'll need council approval.
Do I need approval for a carport in Victoria?
A small carport under 10m² can skip the building permit in specific cases, but be mindful 10m² is not an adequate size for a car to fit under. Therefore an approval process is likely needed.
Do I need approval for a carport in Queensland?
Usually approved via a certifier. Only a tiny freestanding carport (under 10m², under 2.4m) can skip building approval, and not at all in cyclone regions. Most people use a private building certifier. Check your council's planning scheme too — character and heritage areas typically need approval for every carport.
Do I need approval for a carport in South Australia?
A carport is generally treated as a simple structure that needs building approval, but not planning consent — as long as it fits the standard rules. Typically max 60m² and 5 metres high.
Do I need approval for a carport in WA?
WA is stricter than other states. If the carport attaches to your house, you need a building permit, full stop. Front or boundary carports normally need planning approval as well. Expect an approval process.
Do I need approval for a carport in the NT?
Contrary to common belief, a small freestanding carport — up to 15m², under 2.5m, open-sided and not attached to the house — can be built without a building permit anywhere in the Territory. Anything bigger, attached or enclosed needs building approval through a registered certifier — freestanding structures up to 36m² can instead go through an approved self-certifier.
Do I need approval for a carport in Tasmania?
Often no building permit, but check planning. A carport up to 18m² (or 36m² if it's a prefab kit) can be built without a building permit — but you must check planning first and tell the council when it's done.
Do I need approval for a carport in the ACT?
A carport with no more than two walls, sitting behind the building line and under 3m high, is exempt from planning approval with a roof area up to 50m² — a more generous cap than the ACT gives sheds. Building approval can still apply, so check with a certifier.
Everywhere: Height limits and boundary setbacks always apply, and a heritage or bushfire overlay on your block can flip a "no approval" into "approval needed," whatever the size. Always worth a quick check on your specific address before you commit.
The two kinds of approval
"Approval" is two separate gates — a building permit (is it sound?) and planning approval (does it fit your zone and overlays?). A carport can be exempt from planning approval and still require building approval. This varies by state, councils and zones — the CDC vs DA guide explains the planning side's two lanes.
What it tests
Building permit
Is the structure sound? Engineering, materials, wind loading and the National Construction Code.
Planning approval
Does it fit your zone and overlays? Siting, setbacks, streetscape and neighbourhood rules.
Who assesses it
Building permit
A building certifier (council or private), or no one if your state exempts the size.
Planning approval
The council planner — or no one, where the carport meets your state's deemed-to-comply siting rules.
When a carport needs it
Building permit
Bigger, taller or more enclosed than your state's exemption threshold — or attached to the house in WA.
Planning approval
Forward of the building line, near a street boundary, or on land with overlays — the placement rules a backyard shed never touches.

The traps
Overlays. As with sheds, bushfire, flood and heritage constraints can override exempt development. For example, a carport within a few metres of the house on bushfire-prone land can require non-combustible materials.
Front-of-block placement. Because carports so often sit forward of the building line and near a street boundary, they trip setback and streetscape rules that a backyard shed never touches. This is the structural reason carports are treated more strictly — it's about where they go, not what they are.
Frequently asked questions
What's the difference between building approval and planning approval for a carport?
They are two separate gates — a building permit (is it sound?) and planning approval (does it fit your zone and overlays?). A carport can be exempt from planning approval and still require building approval. This varies by state, councils and zones.
Can I build a carport in front of my house?
Usually not without approval. Because carports so often sit forward of the building line and near a street boundary, they trip setback and streetscape rules that a backyard shed never touches — this is the structural reason carports are treated more strictly. In NSW, for example, the no-approval exemption only applies behind the building line.
Does an attached carport need approval?
In WA, always — if the carport attaches to your house, you need a building permit, full stop. Elsewhere it depends: NSW's exemption can still cover an open carport attached to a single-storey home (it must not rise above the gutter line), while in most other states an attached carport is assessed with the dwelling it joins — expect an approval process.
How big can a carport be without approval in NSW?
An open carport up to 20m² (or 25m² on a block over 300m²), under 3m high and behind the front of your house can usually be built with no approval at all. Bring it forward of the house, or close it in, and you'll need council approval.
Why would a small carport still need approval?
Overlays. As with sheds, bushfire, flood and heritage constraints can override exempt development — for example, a carport within a few metres of the house on bushfire-prone land can require non-combustible materials.
