Owner-Builder Record Keeping (WA)
What to record, why it matters, and how good documentation protects you during inspections, final approval, and future sale.
General information only. Confirm record requirements with your building surveyor or permit authority.
In 30 seconds
- As an owner-builder, you are responsible for project records.
- Records support inspections, compliance, insurance, and final approval.
- Missing evidence is one of the most common causes of delays and disputes.
Why record keeping matters
During construction, many critical elements are concealed — waterproofing, framing, reinforcement, services and membranes.
If evidence isn’t collected at the right time, you may be unable to prove compliance later — even if the work was done correctly.
What records owner-builders should keep
Approvals and permits
- Building permit and approved plans
- Any planning approvals (if applicable)
- Owner-Builder Approval (if required)
Inspection records
- Dates and outcomes of mandatory inspections
- Inspection reports or sign-offs
- Rectification evidence if issues were identified
Trade compliance certificates
- Electrical compliance certificates
- Plumbing and drainage compliance
- Gas and waterproofing certificates (where applicable)
Construction evidence
- Photos of work before it’s covered
- Variation records (what changed and why)
- Receipts and invoices for materials and labour
Common record-keeping mistakes
- Assuming trades will keep records for you
- Only collecting documents at the end of the build
- Failing to record informal changes or variations
- Not photographing concealed work before it’s covered
Reality check
Inspectors and insurers assess evidence — not intent.
If it’s not documented, it effectively didn’t happen.

- Building permit is issued
- Construction begins
