Cost FAQs
A standard 6m x 6m double Colorbond carport runs $8,500-$15,500 in Adelaide, fully engineered with engineered footings for reactive clay, BLD-licensed installation, council Building Rules consent and Builders Indemnity Insurance. Forward-of-dwelling carports add $1,500-$3,500 for the heritage DA process.
Almost always yes. Carports forward of the dwelling, carports above 25m2, carports closer than 1.5m to the boundary, or carports on heritage properties all require Development Approval via PlanSA. Even compliant carports need Building Rules consent. Don't sign with any builder who says 'no council needed' without confirming it on the PlanSA portal.
A carport is typically 30-50% cheaper than an equivalent garage. A standard double carport at $10,000-$15,000 versus an enclosed double garage at $25,000-$45,000. Garages add security and weather sealing; carports add ventilation and a much lower price. For most Adelaide family homes, a carport delivers 80% of the benefit at 50% of the cost.
Tandem carports (6m x 9m typically) span 50% more area, need stronger framing for the longer roof span (wind loads grow non-linearly), and almost always need a council DA (over 25m2 floor area). Expect $12,000-$22,000 fully engineered.
