The recent changes to the Federal GST/HST New Housing Rebate have created one of the biggest financial opportunities we’ve seen for homeowners building laneway and garden suites.
For projects with construction commenced prior to April 2027, homeowners can recover up to the full 13% HST through a combination of federal and provincial rebates.
On a $500,000 project, that could mean up to $65,000 in savings.
1. Who Qualifies for the Enhanced HST Rebate
The enhanced HST rebate provides significant savings on new residential construction. Construction must also begin prior to April of 2027. It’s important to note that the CRA considers excavation to be the start of construction.
Homeowners considering a laneway or garden suite for personal and family use or long term rental use will be able to recover the full HST. It’s important to understand that an ADU built to add more living space, or built a guest house for visiting relatives, will not be eligible for the rebate. It must be someone’s primary residence.
Understanding these requirements early is important. Before moving forward, homeowners should review the eligibility criteria and consider how the HST rebate applies to their specific project.

2. Why Timing Matters
The enhanced rebate creates a limited window for homeowners looking to build.
If your goal is to maximize the financial benefit available, the best approach is to begin planning now.
Starting early gives you time to design the right suite, work through the approvals process, and begin construction while the rebate is still available.
3. Building Doesn’t Start When Construction Begins
When people think about building a laneway or garden suite, they often picture excavation, framing, or concrete being poured.
In reality, construction starts long before any work happens on site.
Every project begins with a property assessment to determine what can be built. From there, the project moves into architectural design, engineering, zoning review, permit drawings, and building permit approvals before construction can begin.
This process typically takes four to six months. More complex properties can take even longer.
That means waiting until the last minute could leave you without enough time to begin construction before the rebate deadline.
