Australian owner-builder guidance by state
What does being an owner-builder involve?
An owner-builder is a property owner who manages residential building work or renovations instead of engaging a registered builder to run the project. Requirements differ by state and often by council.
Typical steps
- Confirm eligibility and any value thresholds in your state
- Work through planning approvals and building approvals
- Engage licensed trades and coordinate sequencing
- Manage site safety, documentation, and compliance evidence
- Complete required inspections and final occupation approvals
Common pitfalls
- Assuming “insurance can wait” until sale (it often can’t)
- Not understanding builder-level responsibility during works
- Starting work before approvals are in place
- Poor documentation and record keeping
- Not checking existing home insurance exclusions during renovations
Why do states differ so much?
Owner-builder approvals, terminology, thresholds, and inspection processes vary by jurisdiction
(and often by council). That’s why we start with your state.
Renovation or extension?
The process is often similar — but the biggest trap is existing home insurance during works.
Each state section will call this out clearly.
