Garden suites and accessory dwelling units have become one of the most talked-about projects in Toronto, driven by zoning changes that made them far easier to build and by a rental market that rewards extra housing. But they're a significant build, so it's worth understanding the full picture before committing.
A garden suite is essentially a small, independent home built in your backyard, with its own kitchen, bathroom, and utilities. Because it's a ground-up structure with full servicing, it costs considerably more than finishing existing space, but it also creates the most flexible new square footage you can add to a property.
The financial case rests on two pillars: rental income and property value. In much of the GTA, a well-built suite can command meaningful monthly rent, and it adds a distinct, sought-after asset to your property. Many homeowners also build them for multigenerational living, giving aging parents or adult children independence while staying close.
The rules matter enormously. Setbacks, height limits, servicing connections, tree protection, and fire access all shape what you can build and where. Toronto has streamlined approvals compared to a few years ago, but a garden suite still requires careful planning and permits, and not every lot qualifies.
Whether a garden suite is worth it comes down to your lot, your goals, and your time horizon. For many GTA homeowners the answer is yes, but it's a decision best made with a feasibility assessment specific to your property. We can help you understand what's possible on your lot before you invest in full design.
