In South Australia, all building renovations must be done by a licensed residential builder, and any work over $12,000 should come with an approved building contract. Working with a licensed builder protects you by law. In addition, you will have peace of mind knowing that all licensed builders must go through a vigorous application process to show they are financially sound, qualified, knowledgeable, and of good character just to be granted a licence.
Be wary of tradespeople suggesting work or materials be separated into multiple payments and always ask for a builder’s licence number if you cannot see one.
