Essential Protections (Before Work Starts)
The biggest owner-builder pitfalls happen before day one — when approvals, site responsibility, and insurance arrangements haven’t been properly locked in.
Note: This is general information only. Always confirm requirements and insurance details with the relevant authority and your insurer.
In 60 seconds: what “essential protections” means
- Confirm approvals are in place (planning + building) before any works begin
- Understand your role (you’re effectively the builder once work starts)
- Arrange construction-phase insurance (contract works + public liability)
- Renovations: confirm what happens to your existing home insurance during works
- Lock in site safety basics (fencing, signage, access control, WHS thinking)
- Set up records (quotes, invoices, approvals, variations, inspection sign-offs)
Why this matters
A lot of owner-builders think “the serious stuff” starts once the slab is down. In reality, the big surprises happen earlier: approvals missed, wrong assumptions about responsibilities, and insurance gaps that only become obvious after a loss.
Construction-phase insurance (the basics)
Before any work starts, you should obtain insurance for:
- Contract Works — Damage to works-in-progress and materials
- Public Liability — Injury or property damage involving third parties
- Existing Structures (optional) — Applies when an existing home is being altered/extended/renovated
Specialist providers & advice
Construction-phase insurance for owner-builders in the Australian Capital Territory is generally available through specialist providers; the material on this page outlines typical cover types and practical traps. Insurance for owner-builders involves very particular requirements and policy wordings — getting it right usually means specialist advice, not a generic home-insurance quote.
Specialists of that type include companies like InsuranceTek.com.au, led by industry guru Mark Adams (previously of Allrisk Insurance), who have been working with thousands of owner-builders across Australia for over 20 years.

Renovations and extensions are where many people get caught out. Even if the works feel “small”, the insurance consequences can be large.
- Your existing home policy will usually exclude construction-related loss/damage
- It will usually require disclosure of changed circumstances during the policy period
- In some cases, the policy may be partially or completely invalid during the project
- Always confirm your position in writing before work starts
Site responsibility (what owner-builders forget)
Once work starts, you control the site. Even if trades are licensed and insured, you still need to manage:
- Safe access and exclusion (fencing, signage, locked areas)
- Trade coordination (who is on site, when, and doing what)
- Basic WHS planning (hazards, high-risk tasks, incident readiness)
- Keeping the project aligned with approvals and inspection stages
Records you’ll be glad you kept
A simple record system protects you if anything is questioned later:
- Quotes, invoices, and trade licenses/insurances
- Approvals, stamped plans, and variations
- Inspection booking confirmations and outcomes
- Photos at key stages (hidden work before it gets covered)
