Construction Insurance for Modular Homes: What Applies During the Build

Modular home insurance protects a dwelling during the build and differs from a standard home policy because the structure is fabricated off-site. In Western Australia, requirements hinge on whether your project is residential building work and crosses the value threshold that triggers home indemnity insurance.

Modular construction splits risk across two locations: modules are fabricated in a controlled facility while your site is prepared, so a single standard policy often leaves gaps. Home indemnity insurance protects you if your builder dies, disappears, or becomes insolvent during construction or within the statutory defect period.

For an experienced modular builder, coordinating these policies is routine. Capsule Builders handles the off-site phase in a structurally independent, steel-framed facility, keeping modules protected until they are ready to move.

Transit Insurance for Relocatable Homes: Covering the Journey to Your Site

Transit insurance for relocatable homes covers the modules while they are moved from the factory to your block, a phase site-built homes never face, and one of the most overlooked requirements in modular projects.

The journey involves real risk: loading, road travel, and crane unloading, and the policy must name the correct route and value. Transit and construction cover are separate policies with separate claim triggers, so a module damaged in transit may not be covered by your construction policy.

A product disclosure statement (PDS) and key facts sheet spell out exclusions, read the loading and unloading clauses specifically. For a fixed-price contract, transit obligation usually sits with the builder; for a cost plus contract it can shift to you.

Modular Home Building Warranty and Ongoing Cover After Handover

Modular home building warranty is the ongoing protection after you take the keys, and in Western Australia it centres on the statutory structural warranty period from practical completion. Once installed and certified, you need a standard building insurance policy reflecting that the dwelling sits on your land.

Insurers assess modular home insurance the same way as a site-built one for ongoing cover, provided it has the required compliance certification and building permit approvals. Your building contract should specify who lodges the permit and who holds the warranty obligation.

Building and Energy, WA Government guidance on home indemnity insurance sets out the statutory requirements that apply to residential building work, including the threshold at which home indemnity insurance becomes mandatory. Australian Building Codes Board maintains the National Construction Code that governs compliance for the completed dwelling.

For ongoing cover, compare policies on total replacement cost (not market value, to avoid underinsurance), natural disaster coverage including flood and storm damage, contents cover, liability coverage, and exclusions on structural defects versus maintenance.

A premium comparison across insurers is worth the effort, because a relocatable home can be priced differently by insurers who do not understand off-site construction. For a structural defect claim, the process starts with the structural warranty under your building contract, so keep all handover documentation.
