If you’re building a modular home in Australia, the structure itself might be the most straightforward part of the process. The insurance side is where things get complicated. Modular housing doesn’t fit neatly into the boxes that standard home insurance policies are designed for, and the gaps can be expensive. A single modular segment lifted by crane can be valued at over $400,000, and if something goes wrong during transport or installation, a standard policy won’t help. Understanding where the gaps are, and what you actually need to get covered, makes the difference between a financial setback and a total loss.

Modular construction is becoming more common in Australia, especially for social and affordable housing through programs like the Housing Australia Future Fund. But the insurance industry hasn’t fully caught up. The risk profile shifts from a traditional build, where value accumulates gradually on site, to one where significant value is created off-site, transported, and then installed in a matter of days. That shift creates gaps that many homeowners and builders don’t see coming. Here’s what you actually need to know.
Four Things to Know About Modular Housing Insurance
Modular housing insurance isn’t a single product. It’s a bundle of coverages that need to span the factory, the road, the crane, and the finished home. The central concept here is modular housing insurance, which is really about managing risk across a delivery chain where responsibility shifts between manufacturers, transport providers, installers, and certifiers.
What I tend to notice is that people focus on the finished home and forget about the journey. The most expensive part of a modular build can happen before the home ever touches the ground. That’s where the gaps live.
Modular Home Insurance Costs and Common Coverage Gaps
Insurance costs for modular homes vary widely depending on how the home is classified, where it’s located, and how it’s used. The table below gives a rough sense of what you might expect, but actual quotes depend on your specific situation.

| Dwelling Type | Annual Premium Range | Key Conditions |
|---|---|---|
| Fixed modular home (full compliance) | $800 – $2,000 | Council approval, NCC compliance, permanent foundation |
| Tiny house on wheels (specialist cover) | $1,200 – $3,000 | Trailer registration, placement details, build standards |
| Modular home in high-risk area | Significantly higher | BAL assessment, flood risk evaluation, specific materials |
| Modular home in transit/installation | Needs specific policy | Transport insurance, crane liability, loading/unloading cover |
That NSW exclusion is a concrete example of how the insurance system hasn’t adapted to modular construction. The home itself, which is the most expensive part of the build, falls through a regulatory crack. If you’re buying a modular home, you need to know exactly what your home warranty insurance covers and what it doesn’t. The same principle applies across other states, though the specific legislation varies.
Build costs for modular homes typically range from $2,200 to $3,300 per square metre, depending on specifications and site conditions. When you’re spending that kind of money, the annual insurance premium is a relatively small cost, but only if the policy actually covers the risks that matter.
Three Insurance Mistakes Modular Homeowners Often Make
Assuming the builder’s insurance covers you
Many buyers assume the builder’s insurance policy protects them if something goes wrong during construction. It usually doesn’t. The builder’s policy covers the builder’s own liability, not your financial interest in the home. If a segment is damaged during transport or installation, you may have no claim. The research from Bellrock Advisory notes that contractors often use waivers or limitation-of-liability clauses for crane operations, leaving the financial responsibility with you. The fix is to take out your own course of construction insurance that names you as the insured party, and check that it covers the full value of the modules from the moment they leave the factory.
Not documenting the build process
Insurers rely on evidence. If you can’t show that your modular home was built to Australian Standards, with proper certification, inspection reports, and electrical and plumbing sign-offs, you’ll either be declined or quoted a very high premium. The research from the Tiny Modular Directory makes this clear: compliance certificates and build documentation are what separate an insurable home from an uninsurable one. Keep every certificate, inspection report, and photo of the build process. If you’re working with a builder, ask at the start what documentation they provide at handover. Good builders know their clients need this paperwork.
Ignoring the transport and installation phase
Modular segments can be damaged during transport, and the crane installation carries significant risk. Segments valued at over $400,000 each are lifted into place, and insurers currently have low appetite for covering loading and unloading activities. The common mistake is to assume that standard transit insurance or the builder’s policy covers this phase. It often doesn’t. You need to specifically arrange coverage for the transport and installation period, including the crane operation itself. This is a separate policy that needs to be in place before the first segment leaves the factory.
Getting Your Modular Home Insured From Start to Finish
Start with a broker who knows modular construction
Mainstream insurers and comparison websites are unlikely to have policies that fit modular homes. A broker who specialises in unusual or non-standard properties can access underwriters that understand the risk profile. Tell them exactly what you’re building, where it will be located, and how you intend to use it. The broker can then identify the right coverages for the factory, transport, installation, and ongoing occupancy phases. If you’re also looking to monitor the build site during construction, a wireless security camera can help document the process and provide evidence if something goes wrong.
Get your compliance paperwork in order
Before you approach an insurer, gather every document that demonstrates compliance. This includes council approval, National Construction Code certification, engineering sign-offs, electrical and plumbing certificates of compliance, and inspection reports from every stage of the build. If your home is built to Australian Standards with proper certification, you’re much closer to a standard insurance pathway. If it’s an owner-built project, you’ll need independent inspection reports and certification from licensed tradespeople to strengthen your case.
Check the coverage for transport and installation separately
This is the phase where modular housing differs most from traditional construction. The risk of damage during transport and crane installation is real, and standard policies don’t cover it. Ask your broker about a course of construction policy that specifically includes transit and installation coverage. Make sure it covers the full replacement value of the modules, not just the raw materials, and that it names you as the insured party. The UK’s BOPAS scheme shows that lender and insurer confidence improves when certification is designed for the full delivery chain, not just the finished product.
Plan for the long term: renewals and future changes
Once your modular home is installed and occupied, you’ll need a standard home and contents policy. But not all insurers will renew automatically, especially if they’re unfamiliar with modular construction. The ABCB’s work on a National Voluntary Certification Scheme for MMC manufacturers could eventually make modular homes easier to insure, but that framework is still in consultation. In the meantime, keep your documentation updated and review your policy annually. If you make changes to the home, such as adding a loft or converting to a rental, tell your insurer before the change happens.

Why Insurance Is the Missing Piece in Australia’s Modular Housing Push
Modular housing can deliver compliant homes roughly 30% faster than conventional builds, and programs like the Housing Australia Future Fund are betting on that speed. But speed without trust doesn’t scale. The UK parliamentary inquiry found that lack of confidence among valuers, insurers, and mortgage lenders was a key barrier to modular uptake, partly because innovative systems lacked long-term performance data. Australia is at a similar crossroads. The ABCB’s National Voluntary Certification Scheme could build that trust, but only if insurers and lenders are part of the framework from the start. For now, the responsibility falls on buyers and builders to understand the gaps and get properly covered before the first module leaves the factory.
