A garden suite is a secondary dwelling unit located on the same lot as a primary home, typically in the backyard. Often referred to as a coach house, laneway house, or backyard suite, these small units offer independent living space complete with a kitchen, bathroom, and bedroom. In Toronto, garden suites have become increasingly popular as a way to address housing shortages, provide rental income, or accommodate multi-generational living arrangements.
Toronto recently passed new zoning regulations that allow for garden suites to be built on properties that already have a main house. This has created opportunities for homeowners to build secondary units that provide additional living space or rental options.
Garden suites are popular because they offer flexibility—whether it's creating space for elderly parents, adult children, or tenants. They also help increase property value and contribute to Toronto's growing need for affordable housing.

FAQs About Building a Garden Suite in Toronto
The cost to build a garden suite in Toronto varies widely depending on factors such as size, design, and material choices. However, homeowners can generally expect the total cost to range from $200,000 to $400,000.
These estimates include construction, design, permits, and utilities but can fluctuate based on several factors such as site conditions and customization.
To understand the total cost, it’s helpful to break down the various components involved in building a garden suite.
Hiring an architect or designer is the first step. Depending on the complexity of the project, expect to pay between $10,000 and $20,000 for design services, including architectural drawings, engineering consultations, and interior layouts.
In Toronto, building a garden suite requires proper permits. The cost of permits can range from $5,000 to $10,000, depending on the scope of the project. This covers building permits, zoning checks, and inspections by the city to ensure compliance with local regulations.
The bulk of the cost comes from construction. This includes materials like concrete, framing, insulation, windows, and roofing, as well as labor costs for builders and contractors. Construction costs can range from $150 to $350 per square foot, depending on the quality of materials and labor.
Once the garden suite is complete, you’ll need to invest in landscaping and exterior finishes, which can add another $5,000 to $15,000 to your budget. This includes pathways, driveways, lighting, and any necessary adjustments to the yard.
Several factors can influence the total cost of building a garden suite.
Larger suites or those with multiple floors will naturally cost more. A two-bedroom garden suite with high-end finishes will be significantly more expensive than a smaller, simpler unit.
Premium materials like high-end countertops, flooring, and energy-efficient windows will increase the overall cost. Using sustainable or eco-friendly materials can also drive up the price, although they may offer savings in the long term through energy efficiency.
Site preparation is another major cost factor. If your property requires extensive leveling, excavation, or foundation work, the costs can increase significantly. Additionally, integrating a garden suite into an existing landscape can require adjustments to fences, trees, or other backyard features.
Connecting the garden suite to utilities such as water, sewer, and electricity can be a complex process. Depending on the proximity to existing infrastructure, this can add anywhere from $10,000 to $50,000 to your total budget, particularly if extensive plumbing or electrical work is needed.
The timeline for building a garden suite varies depending on several factors, such as permit approval and the complexity of the design. On average, the entire process takes between 6 to 12 months.
Before construction begins, homeowners must secure the necessary permits from the City of Toronto. This involves submitting architectural plans, obtaining zoning approval, and undergoing several inspections. While this process can take several months, it’s essential to ensure your garden suite is built legally and safely.
Building a garden suite requires navigating Toronto’s zoning bylaws and ensuring compliance with local regulations.
Toronto has specific zoning requirements for garden suites, including restrictions on size, height, and distance from property lines. Homeowners must ensure their project complies with these rules before construction can begin.
Permits are essential to avoid fines and delays and to ensure that your garden suite is legally compliant.
When designing your garden suite, it’s important to balance style, functionality, and sustainability. Here are some design ideas to help you maximize value.
Since garden suites are often smaller than the main house, it’s important to design a space-efficient layout. Open floor plans, multi-functional furniture, and minimalistic designs can make the unit feel larger and more comfortable.
Adding energy-efficient appliances, solar panels, or sustainable materials can increase the long-term value of your garden suite. While these features may come with a higher initial cost, they can reduce energy bills and appeal to eco-conscious tenants or buyers.
Consider creating a flexible space that can serve multiple purposes. For example, a garden suite could function as a rental unit now but be used later as a home office, guest house, or living space for aging parents.
Building a garden suite offers several benefits, both financial and personal.
One of the most appealing reasons to build a garden suite is the potential for rental income. With Toronto’s high housing demand, many homeowners rent out their garden suites to generate additional income, which can help offset the cost of the initial construction.
A well-designed garden suite can significantly increase the overall value of your property. Potential buyers often see these units as a valuable asset, especially in areas where housing affordability is a concern.
Garden suites offer a flexible housing solution for multi-generational families. Whether you’re accommodating aging parents or providing a separate space for adult children, a garden suite can create an independent living environment while keeping family close.
