We created this resource after going through the process ourselves for a project on Russell Island.
Everything here is straightforward, up-to-date, and focused on helping you protect your build, your budget, and your peace of mind.
What is it?
Owner-builder insurance is a combined policy that includes Contract Works (also called Construction Insurance) and Public & Products Liability. Contract Works covers the value of the building work in progress, materials on site, and plant/equipment against loss or damage from events such as fire, storm, flood, theft, vandalism and accidental damage. Public Liability covers you for legal liability if a third party (tradie, visitor, neighbour) is injured or their property is damaged because of your building project. Premiums are calculated on the total contract value (typically including labour and materials) and the policy runs from the date works start until practical completion.
Why does it exist?
Standard home and contents policies specifically exclude any work that requires a building permit or is carried out under an owner-builder permit. Banks, councils and strata bodies also recognise that owner-builders carry the same risks as licensed builders during construction, yet they have no automatic builder’s all-risk cover. This insurance was created to fill that gap and to meet state-based legal requirements for Public Liability on sites where building work exceeds certain values ($5,000–$20,000 depending on state/territory).
Do I need it?
It's essential in most cases, especially if you're using a construction loan or need council approval. Public Liability insurance (at least $5 million cover) is required or strongly recommended by most states and territories before issuing a building or owner-builder permit for projects over $5,000–$20,000 (depending on your location—check your state's rules). Lenders and councils often won't proceed without proof. Contract Works insurance isn't legally mandatory anywhere, but every bank requires it for construction loans to safeguard materials and work-in-progress, and nearly all owner-builders get it once they understand the risks of uncovered losses like storms or theft.
When should I get it?
You should arrange the policy before any physical work starts on site and after you collect your owner-builder permit or building approval. Cover must be in force the day the first tradie, supplier or you yourself step on site with tools or materials. Most policies can be issued same-day or next-day once you have your project value and postcode.
Our Story: Why We Recommend Owner-Builder Insurance (Even Though We Can't Get It Ourselves)
During a recent call with a family member who's owner-building in central Queensland, I asked for advice on prepping for our own project on Russell Island. We covered basics like permits, trades, and materials for a kit home. He's using one from Mecano, so he shared notes on deliveries and site setup. When I mentioned my checklist, he added, "Get owner builder insurance. A mate's storm damage claim was a wake-up call for me." I noted it down alongside other to dos.
That led us to quote policies for our build. As an island without road access (ferry-only from Redland Bay), we're excluded from owner-builder cover. Insurers like Vero and QBE reject it due to "Island location risk" delayed emergency access, higher claim costs from logistics, and challenges for assessors. We tried over a dozen providers, all declined. Right now, that leaves us taking full financial responsibility for any accident on site a tree falling on the frame, a storm hitting materials, or someone getting hurt. Without coverage, we're personally on the hook for potentially massive costs, and honestly, it makes us nervous. It's not a position we want to be in, exposed to risks that could wipe out our savings in one event.
Coverforce stood out by engaging directly. They reviewed our details on a call, explained the standard exclusions for non-road-access islands, and escalated to an underwriter to check if Russell's community (over 2,000 residents, local hardware) could qualify. It couldn't, but their clear advice on mainland risks and mitigation options like site security built trust.
They're straightforward approach and willingness to help is why we recommend you connect with them for a quote.
We can't get this cover, but it doesn't change our view: for accessible sites, it's essential against real threats like site damage or lawsuits - get yours and build without that same worry hanging over you.
