First Home Owner Grant and Modular Homes in Western Australia
For many first home buyers in Western Australia, the First Home Owner Grant can make a meaningful difference when taking the step into home ownership. As modular housing continues to grow in popularity, there has been understandable confusion around how modular homes are treated under the grant.
In early 2026, the Commissioner of State Revenue clarified this position, providing important guidance for buyers, builders and the broader housing industry.
What the clarification means
RevenueWA has released Revenue Ruling FHOG 5 Modular Homes, which explains how modular home contracts are assessed for the purpose of the First Home Owner Grant. The key distinction is whether the buyer is considered to be entering into a comprehensive home building contract or acting as an owner builder.
This classification affects when a buyer can apply for the grant and when payment may be approved.
Comprehensive home building contracts versus owner builders
Under the ruling, a buyer building a modular home may fall into one of two categories.
If the contract covers the construction and completion of the home in a comprehensive way, including delivery and installation, the buyer is generally treated the same as someone building a traditional home under a standard building contract.
If the buyer instead manages multiple contracts or takes responsibility for coordinating key stages of the build, they may be considered an owner builder. In this case, the timing and process for applying for the First Home Owner Grant can be different.
The Revenue Ruling provides detailed guidance on how these scenarios are assessed, helping buyers understand their obligations and eligibility.
Updated guidance from RevenueWA
To support clarity across the industry, RevenueWA has updated its public information to reflect the treatment of modular homes under the grant. This includes updated guidance within the First Home Owner Grant fact sheets and lodgement materials.
For first home buyers, this means there is now clearer direction on how modular homes fit within existing grant frameworks.
Why this matters for modular home buyers
Modular homes offer a faster, more controlled and often more sustainable pathway to home ownership. Clear guidance from RevenueWA helps ensure that buyers choosing this modern building method are treated fairly and understand how to plan their grant application.
At MIRA Residential, we believe modular homes should be designed for life and built for the future. Clear regulatory guidance supports confidence for buyers who want to build smarter without uncertainty around incentives.
Getting advice
As every build is different, buyers are encouraged to seek advice early, particularly if they are unsure how their contract may be classified. RevenueWA has made support available for enquiries relating to the ruling, and builders experienced in modular construction can also help guide the process.
