About Builder in South Australia
Builders manage major construction work — new homes, large extensions, structural alterations, second storeys, and substantial renovations. In South Australia, builders must be licensed by Consumer and Business Services for any work over $12,000 (with limited exceptions for some specific trades). Builders coordinate all the other trades on a major project.
Common builder jobs in SA homes:
- New home construction
- Extensions and additions (single and double storey)
- Major renovations
- Granny flats and secondary dwellings
- Carport and garage construction
- Structural alterations (load-bearing wall removal, openings)
- Insurance work for major damage
- Heritage restoration (specialist work)
- Project management for renovations
- Knockdown-rebuild projects
What it usually costs: New home builds in Adelaide $2,200–$3,500+ per sqm depending on inclusions and finish level. Single-storey extensions $2,500–$4,500 per sqm. Double-storey additions $3,000–$5,500 per sqm. Granny flats $80,000–$250,000 depending on size and complexity. Major bathroom or kitchen renovation $25,000–$80,000+.
Hiring tips: Verify the builder holds a current SA Building Work Contractor's License — without it, contracts over $12K are legally unenforceable. Always use a Master Builders SA or HIA contract for large work — these provide significant consumer protection. Get a fixed-price quote with detailed scope wherever possible. Check the builder's recent work (visit completed projects), references (call past clients), and CBS history (any complaints or claims). For projects over $40,000, builders warranty insurance is required by law in SA — verify it's in place. Beware of any builder asking for large upfront payments — typical schedules have multiple progress payments tied to construction stages.
