A single carport in Adelaide costs $3,000–$8,000 to build in 2026. A double carport costs $6,000–$15,000. Price depends on size, roofing material, and site access. Colorbond® steel sits at the top of that range. It holds up best against Adelaide’s hail and UV. A basic timber-frame kit costs less upfront, but it needs more upkeep over time. Most Adelaide metro councils require approval for a new carport, unless it meets exemption rules. Adelaide’s reactive clay soil can also add to footing costs on some blocks. This guide breaks down what drives carport pricing in 2026, so you know exactly what you’re paying for.
Single vs double carport pricing in 2026
A single carport (one car, roughly 3m x 6m) costs $3,000–$8,000 supply and install in 2026. A double carport (around 6m x 6m) costs $6,000–$15,000. The lower end of each range covers a basic gable or skillion roof on a concrete slab. The upper end reflects taller posts, a longer span, or a higher-pitched roof. A sloping block adds cost too, since it needs extra excavation and retaining. Attaching the carport to your house wall usually costs less than a free-standing structure. You save on one or two posts and some roofing. Get a fixed, itemised quote before you sign anything. The size and roof style you choose has the biggest effect on the final price.
Colorbond® vs timber or steel kit
Most Adelaide homeowners choose Colorbond® steel for carport roofing and posts. It holds up through hail, strong UV, and salt air near the coast. It also needs almost no maintenance. A basic timber-frame carport can cost $500–$1,500 less upfront. But timber posts and rafters need repainting or oiling every few years. They’re also more prone to termite and weather damage in Adelaide’s climate. Flat-pack steel kit carports sit in the middle price-wise. Many kits don’t meet Adelaide wind ratings or council approval requirements, though, which can mean costly rework later. If you want a structure that lasts with minimal upkeep, Colorbond® is the better long-term choice.
Council approval in Adelaide metro
Most Adelaide metro councils require approval for a new carport. Exemptions usually apply only if it’s under 20 square metres, set back from the street, and not attached to habitable rooms. Rules vary between councils, so check before you commit to a design. Approval typically adds two to six weeks to your timeline. It also adds $300–$800 in council and drafting fees, depending on the complexity of your build. A licensed builder who works across Adelaide metro daily will know exactly what each council needs. We can lodge the paperwork on your behalf.
Reactive clay soil and footing costs
Adelaide has a lot of reactive clay soil, especially in the Hills and northern suburbs. This soil expands and contracts with moisture. As a result, carport footings often need to go deeper or be engineered. This can add roughly $500–$2,000 to the job on affected blocks. Skipping this step to save money is a false economy. Footings that move will crack slabs and posts within a few years. A proper site inspection before quoting tells you exactly what your soil needs. That way, the price you’re given up front is the price you actually pay.
Kit-home price vs a certified build — what you’re really paying for
A cheap kit-home carport can look like it saves you thousands. But the sticker price usually skips council-compliant engineering, site-specific footings, and installation labour. Add those costs in, and the total often matches what a licensed builder charges for a certified structure. The difference is, you’d be managing the approvals and trades yourself. A certified build means the carport is signed off, insured, and built to Australian wind and structural standards for Adelaide conditions. If an open carport isn’t quite right for you, compare it against our sheds and garages range too. These offer fully enclosed storage and better security.
