What Exactly Is a Garden Suite?
A garden suite is like a mini home tucked into your backyard. It has everything needed for comfortable living—bedroom, bathroom, kitchen, and a cozy place to hang out. Many homeowners use them as guest houses or rent them out for extra income. With the right design, even a small space can be both stylish and practical.
Step One: Check What’s Allowed on Your Property
Before jumping into floor plans, it’s essential to make sure your property qualifies. In Toronto (which includes Scarborough and Etobicoke), many residential lots can host a garden suite, but there are specific rules around setbacks, size, and parking. The City of Toronto website has zoning maps to guide you. Once you’re sure it’s a go, the real planning begins.
Designing a Garden Suite That Works for You
Now the fun part—design. Work with a local architect to shape a plan that makes the most of your backyard. Look for modern designs tailored for small spaces—these offer both function and style. Natural light, privacy from the main house, and smart layouts go a long way. This part usually takes 4–8 weeks, depending on how detailed your vision is.
Utility Connections: The Less Glamorous But Essential Bit
Your garden suite needs access to water, electricity, and possibly gas. Usually, everything connects back to your main home.
– Water: A ¾-inch line usually does the trick.
– Electricity: You may need a subpanel if your current one can’t handle the load.
– Gas: Used for heating or cooking—it requires a pro to assess and install safely.
Expect utility hookups to cost somewhere between $5,000 and $15,000.
Construction Choices: Should You Go Modular or Traditional?
Modular builds are gaining popularity—and for good reason.
– They’re built off-site, then delivered and assembled on your property.
– You’ll save time, reduce on-site mess, and often spend less overall.
– Expect to pay between $150,000 and $250,000 depending on the layout and finishes.
Traditional construction offers more design freedom but often comes with a longer timeline and bigger price tag—anywhere from $200,000 to $300,000.
How Long Will It All Take?
Here’s a general idea:
• Zoning & Permits: 1–2 months
• Design: 1–2 months
• Construction Permits: 1–2 months
• Build Time: Modular (3–4 months), Traditional (7–9 months)
In total, expect about 6–8 months for modular and up to 15 months for traditional builds.
Keeping Mold and Moisture Away
Modular builds are created in controlled environments, which means they’re usually well protected from mold from the start. Still, you’ll want to ensure your foundation is well-drained and sealed. It’s worth hiring a contractor who knows how to prep a site properly.
What Might Go Wrong (and How to Stay Ahead of It)
No project is without hiccups. Here are a few to plan for:
– Permit delays
– Unpredictable soil or utility issues
– Price increases due to material shortages
– Bad weather (for traditional builds)
– Meeting building codes
Choose eco-friendly materials where you can—they last longer and can help with grant eligibility.
