Owner-Builder Projects in Adelaide
An owner-builder is a homeowner who takes on the role of head contractor for their own project, coordinating trades directly instead of hiring a licensed builder. Done well it can save 15 to 25% of the total build cost. Done poorly it is a very effective way to lose your savings, your marriage, and 18 months of your life.
Best for
- •People with trade or construction backgrounds
- •Simple projects (extensions, garages, small renovations) where the risk is contained
- •Anyone genuinely willing to spend 20+ hours a week managing their build
Typical timeline
Owner-builder projects typically run 30 to 50% longer than a licensed builder equivalent because trade coordination is harder without existing relationships.
Council & overlay notes
Owner-builder consent is the same as builder-led consent. The council does not care who is building it, only that it complies.

Key decisions you'll face
Owner-builder permit
SA requires an owner-builder permit for works over $12,000 in labour and materials. The permit is issued by CBS after a short online course. You can only get one per 5 years.
Insurance and warranty
Owner-builders cannot buy home building compensation insurance. This restricts your ability to sell within 5 years of completion.
What you personally can do vs what needs a trade licence
Plumbing, gas, and electrical always need licensed trades. Most other work you can do yourself if you know what you are doing.
Where builds go wrong
Time cost
Owner-builder is a second job for the duration of the build. Most people underestimate how much time trade coordination consumes.
Resale restriction
You cannot sell an owner-built home within 5 years of completion without disclosing owner-builder status. This can reduce market value.
Warranty exposure
You carry the warranty risk for any defects, because there is no licensed builder to fall back on.
How the process runs
- 1
Realistically assess your time and skills
Owner-builder is a second job. Talk to someone who has done it before you commit.
- 2
Do the CBS owner-builder course
The online course is a legal requirement and covers the basics of contract law, insurance and consumer protection.
- 3
Get your permit and consents
CBS owner-builder permit plus council planning and building consent.
- 4
Line up your trades before you start
Book plumbers, electricians and framers well ahead. Owner-builders often struggle to secure trades without an existing builder relationship.
- 5
Manage the sequence
The critical path is the order of trades. Get this wrong and everything cascades.
Common questions
Do I need a permit to be an owner-builder in SA?▾
Yes, for works valued over $12,000 (labour and materials combined). CBS (Consumer and Business Services) issues owner-builder permits after a short course.
Can I be an owner-builder more than once?▾
You can be issued one owner-builder permit every 5 years in South Australia.
Can I get a home loan as an owner-builder?▾
Some lenders will lend, but expect stricter LVR limits, more documentation and progress-inspection-based drawdown.
Can I sell my owner-built home?▾
Yes, but for 5 years after completion you must disclose the owner-builder status to any buyer. Buyers usually pay less because there is no home warranty backstop.
What can I not do myself?▾
Plumbing, gas fitting and electrical work must be done by licensed trades. Structural design must be signed off by an engineer. Most other work you can do if competent.
