Practical guidance for Australian businesses, professionals and families navigating insurance, risk and resilience.

If you're planning to build or renovate your own home in Queensland as an owner builder, the insurance requirements kick in from the moment you pick up a permit. Getting the wrong cover — or skipping it entirely — can leave you personally liable for injuries, incomplete work, and costs that run well into six figures. This guide covers what cover you need, what Queensland law requires, what drives your premium, and how to get a policy that actually fits your project.


What Is Owner Builder Insurance?

Owner builder insurance is a broad term for several types of protection that apply when a homeowner takes on the role of principal contractor for their own residential construction or renovation. In Queensland, it's not a single policy. It's a combination of covers that work together to protect you, your workers, your site, and anyone who buys the property after you.

The main types to understand are:

  • Home warranty insurance (also called residential construction insurance or statutory insurance)
  • Public liability insurance
  • Contract works insurance (also called construction works or builders risk cover)
  • Workers compensation (if you engage workers)

Each does a different job. Assuming one covers the others is one of the most common — and costly — mistakes owner builders make.


Queensland's owner builder framework sits under the Queensland Building and Construction Commission Act 1991 and the QBCC's licensing rules. Before you can act as an owner builder in Queensland, you need an owner builder permit from the QBCC for any residential work valued at more than $11,000.

Residential Construction Insurance (Home Warranty)

Queensland is one of the few states with a mandatory home warranty scheme that specifically covers owner builders. Under the QBCC's Residential Construction Insurance (RCI) scheme, if you sell your home within six years and six months of completing the work, the buyer is entitled to protection against defects in what you built.

This insurance is arranged directly through the QBCC — not through a private insurer. You pay a premium to the QBCC as part of the permit process, and the cover attaches to the property. If you never sell, this particular requirement may not be triggered, but confirm your position with the QBCC and a qualified broker before making that assumption.

Public Liability Insurance

Public liability is not optional. It covers you if a third party — a visitor, neighbour, or passerby — is injured or has their property damaged as a result of your construction activities. On a live building site, that risk is real. Unsecured scaffolding, debris, uneven ground, and open trenches are all common sources of claims.

Most lenders and councils also require evidence of public liability cover before releasing funds or approving permits. A minimum of $5 million is standard across Queensland, though $10 million or $20 million limits are common on larger projects.

Contract Works Insurance

Contract works insurance protects the physical structure being built. If a storm rolls through mid-construction and tears the roof frame off, or a fire damages framing before lock-up, this cover pays to rebuild from that point rather than starting over out of your own pocket.

It typically runs from the start of construction through to practical completion, with some policies extending into a maintenance or defects period. Coverage generally includes materials on site, materials in transit, and the structure itself as it takes shape.

Workers Compensation in Queensland

If you hire workers, subcontractors who aren't themselves licensed and insured, or labour-hire staff, you may have obligations under Queensland's workers compensation legislation. The scheme is managed through WorkCover Queensland and certain self-insurer arrangements.

Many owner builders assume that using subcontractors removes their liability. That's not always the case. If a subcontractor can't demonstrate they hold their own workers compensation cover, you may be treated as their employer for the purposes of a claim. A broker can help you map out your actual obligations before anyone sets foot on site.


What Affects the Cost of Owner Builder Insurance in QLD?

Premiums for owner builder insurance in Queensland aren't publicly standardised and vary widely depending on a range of factors. Here's what insurers and underwriters typically look at:

Project value. The total construction value is the primary driver. A $150,000 bathroom and extension project carries a very different risk profile from a $900,000 new build.

Project type. New builds, renovations, extensions, and demolitions each come with different risk profiles. Structural work on an existing occupied home, for example, tends to attract higher premiums than a straightforward new build on a vacant lot.

Location. Queensland's geography matters. Coastal and cyclone-prone areas in North Queensland attract loading from insurers due to the higher likelihood of weather events during construction. Flood-prone land also affects pricing.

Duration. Contract works policies are partly priced on how long the site will be active. A project expected to run 18 months carries more exposure than one wrapping up in six.

Your experience. Some insurers ask about your building background or whether you've engaged a licensed builder to supervise. Demonstrated experience or professional oversight can work in your favour on premium.

Sum insured. Underinsuring your project is a risk in itself. If you insure a $600,000 build for $400,000 and suffer a total loss, you absorb the gap. Getting the sum insured right matters as much as getting the right policy type.

Because pricing varies by insurer and isn't publicly available, the most reliable way to understand your actual cost is to speak with a broker who works in the construction insurance space and can approach multiple underwriters on your behalf.


Common Gaps in Owner Builder Cover

Even when owner builders have some insurance in place, gaps appear that create real exposure. The most frequent ones include:

Assuming your home and contents policy covers construction. Standard home and contents policies exclude construction works. Once you start building, your existing policy may not respond at all — and you may need to notify your insurer of the change in risk.

Not insuring materials off-site. Timber, fixtures, and fittings stored at a supplier's warehouse or in transit aren't automatically covered under a contract works policy. Check whether your policy extends to materials not yet on site.

Forgetting the maintenance period. Once practical completion is reached, your contract works policy typically ends. If a defect surfaces in the weeks after handover, you may have no cover unless your policy includes a maintenance period extension.

Underinsuring labour costs. If you're doing much of the work yourself, you might insure only the materials. But if a major event requires you to bring in tradespeople to rebuild, labour costs can exceed the materials bill. Your sum insured should reflect the full cost to rebuild.

Public liability gaps between trades. When multiple subcontractors are on site, there can be disputes about whose liability policy responds to a given incident. As the owner builder, you're the principal contractor. Your public liability policy is the backstop.


How to Get Owner Builder Insurance in Queensland

There are broadly three ways to arrange cover:

Direct from an insurer. Some insurers offer owner builder products online or by phone. This works if your project is straightforward and you know exactly what you need. The risk is that you may not realise what's missing until a claim is declined.

Through a comparison platform. Online comparison tools can surface a range of quotes quickly and work well for simple, standard risks. Owner builder projects — particularly larger or more complex ones — often fall outside the parameters these platforms handle well.

Through a specialist broker. A broker who works in construction insurance can assess your specific project, identify the covers you actually need, approach multiple insurers and underwriters, and structure a package that fits. If your project is in a cyclone zone, involves demolition, or has an unusual scope, a broker is the most reliable path to adequate cover.

ABS Insurance Brokers works with builders, construction businesses, and owner builders across Australia. As part of the Steadfast Network, the team has access to a wide range of insurers and specialist underwriters — which means they can source cover for projects that don't fit neatly into an off-the-shelf product. You can contact the team by phone or submit an online quote request to get the process started.


Before You Break Ground: A Practical Checklist

Use this as a working reference before your project starts:

  • Confirm whether your project value exceeds the $11,000 QBCC permit threshold
  • Apply for your owner builder permit from the QBCC
  • Understand your obligations under the QBCC's Residential Construction Insurance scheme
  • Arrange public liability insurance with a limit appropriate for your project
  • Arrange contract works insurance covering the full construction period
  • Confirm workers compensation obligations for any workers or uninsured subcontractors
  • Notify your existing home insurer of the change in risk
  • Review your sum insured to ensure it reflects the full rebuild cost, including labour
  • Check whether your policy covers materials in transit and off-site storage
  • Confirm the maintenance period extension on your contract works policy

This list is a starting point, not a substitute for advice specific to your project.


FAQs

Do I need insurance before I get my owner builder permit in Queensland?
You need your insurance arrangements in place before construction begins. The QBCC permit process requires you to arrange Residential Construction Insurance through the QBCC as part of the application. Public liability and contract works cover should both be in place before any work starts on site.

Is owner builder insurance the same as home warranty insurance in QLD?
No. Residential Construction Insurance is one component of the cover you need — it protects future buyers against defects. Public liability and contract works insurance are separate policies that protect you during the construction process itself.

What happens if I don't sell the property? Do I still need QBCC insurance?
The QBCC's Residential Construction Insurance is triggered when you sell the property within six years and six months of completing the work. If you never sell, the buyer protection element doesn't come into play — but confirm your specific obligations with the QBCC and a broker before making decisions based on that assumption.

Can I use my existing home and contents policy to cover the construction?
Generally, no. Standard home and contents policies exclude construction works. Notify your insurer once construction begins, as the change in risk may affect your existing cover. A separate contract works policy is needed for the build itself.

How much does owner builder insurance cost in Queensland?
Premiums vary based on project value, location, project type, duration, and the specific covers included. There's no single standard price. The best way to understand your cost is to speak with a broker who can approach multiple insurers and provide a quote based on your actual project details.

Do I need workers compensation if I'm doing most of the work myself?
If you engage any workers or uninsured subcontractors, you may have workers compensation obligations under Queensland law. WorkCover Queensland administers the scheme. The key question is whether the people working on your site hold their own valid cover. A broker can help you assess your obligations before you engage anyone.

What is the difference between contract works insurance and public liability insurance?
Contract works insurance covers physical loss or damage to the structure being built, including materials on site. Public liability covers your legal liability if a third party is injured or has their property damaged as a result of your construction activities. You typically need both running simultaneously during a build.
