Record-keeping for owner-builders (NSW)
Simple, practical record-keeping that supports inspections, insurance, completion approval, and selling later — without turning your project into paperwork hell.
Note: This is general information only. Your certifier may require additional records.
In 30 seconds
- Good records are how you prove compliance — not how well the job was built.
- Most delays happen because evidence was never collected, not because work was wrong.
- If it’s not written down or saved, it effectively doesn’t exist.
- A simple folder structure + variation log solves most problems.
Why record-keeping matters
As an owner-builder, you are treated as the builder. That means you’re expected to produce evidence when it’s requested — sometimes months later.
- Certifiers rely on records to issue inspection sign-offs and final approval
- Insurers rely on records when assessing claims
- Missing records can delay occupation or completion certificates
- Selling later can trigger document requests you didn’t expect
What records you should keep
- DA / CDC approvals and conditions
- Approved construction drawings
- Updated plans if changes occur
- Inspection booking records
- Inspection outcomes / sign-offs
- Engineer certificates (if required)
- Trade licences (where required)
- Compliance certificates (electrical, plumbing, waterproofing)
- Invoices/receipts for major works
- Hidden work (before it’s covered)
- Key stages (footings, framing, waterproofing)
- Date-stamped photos where possible
A simple record-keeping system that works
You don’t need software or spreadsheets — just consistency.
Keep everything digital if possible, backed up somewhere safe. Share relevant folders with your certifier when requested.
Variations: the record that saves projects
Owner-builders almost always change something. The problem isn’t the change — it’s not recording it.
- What changed?
- When?
- Why?
- Who approved it?
- What document was updated?
If you only keep one record, keep a variation log.
