Thinking of adding a second home on your property? Whether you’re after rental income, a family suite, or a property value boost, Garden Suites vs. Laneway Suites are two powerful options for Toronto homeowners in 2025. But which one is right for your lot—and your budget?

I’ve built both types—helped clients from Scarborough to High Park design, permit, and construct these detached backyard homes. So here’s a practical breakdown based on real projects, up-to-date rules, and what actually works in Toronto today.
What Is a Garden Suite vs. a Laneway Suite?
Both are secondary units you build in your backyard. They’re self-contained with a kitchen, bathroom, and sleeping area, but can’t be sold separately—they stay part of your property.
| Feature | Garden Suite | Laneway Suite |
|---|---|---|
| Where it’s built | Any backyard (no laneway required) | Must face a public laneway |
| Popular areas | Scarborough, North York, Etobicoke | High Park, The Annex, Junction |
| Access | Through side yard or rear path | From public laneway (separate access) |
| Size range | 500–800 sq. ft. typical | 400–600 sq. ft. typical |
| Use cases | Rental income, in-law suite, office, studio | Rental income, guest unit, garage + suite combo |
| Build cost (2025) | $150,000–$300,000 | $175,000–$350,000 |
Why Homeowners Choose Garden Suites

More Flexibility, Less Red Tape
Since you don’t need a laneway, more Toronto lots qualify—especially in suburbs like Scarborough or North York.
Advantages:
- No laneway needed – just a backyard and proper zoning.
- Faster to plan – pre-fab options save time and money.
- More layout options – place it near your fence, shed, or garage.
- Affordable ROI – pre-fab units can cost $200K, rent for $2,000/month.
Example: I built one in East York with a small garden bed and privacy fence. It became a quiet, energy-efficient rental for $2,200/month.
Why Homeowners Choose Laneway Suites
Great for Central Locations with Laneways
If you’re in areas like The Junction or Leslieville and have laneway access, you can maximize space and privacy.
Advantages:
- Separate entrance – tenants access from the laneway.
- Build above a garage – saves backyard space.
- Stylish and urban – renters love the ‘loft’ feel.
- Fast permit approvals – City has streamlined laneway permits since 2018.
Example: I completed one in Parkdale with a carport below. The tenant loved the modern vibe, and the owner kept their backyard patio untouched.
2025 Rules and Requirements: What’s Changed?
In late 2024, Ontario Regulation 462/24 updated zoning rules for Garden Suites. Here’s how the key requirements compare:
1. Zoning
- Garden Suites: Allowed in R, RD, RS, RT, RM zones—no laneway required.
- Laneway Suites: Same zones, but must front a public laneway (not private).
2. Emergency Access
- Garden Suites: Need a 1m wide path or alternative (like sprinklers).
- Laneway Suites: Laneway itself acts as access.
Pro Tip: I added a $7,000 sprinkler system in Leaside to pass fire code when access was tight.
3. Parking
- No car parking required for either.
- Garden: Must provide 2 bicycle spots.
- Laneway: Only 1 bike spot, but garage options available.

Incentives: You can defer development charges if the unit remains part of your lot for 20 years. First Nations homeowners may also access RRAP grants.
FAQs from Homeowners (Real Questions I Get)
Can I build both a garden suite and a laneway suite in Toronto?
No. The City only allows one detached secondary unit per lot, plus your main home and possibly a basement suite.
How do I know if I have a public laneway?
Check your property survey or the City’s zoning map. It must be City-maintained to qualify.
Which is cheaper?
Garden suites are generally cheaper—especially with pre-fab models. Laneway suites cost more due to trenching and garage construction.
What rents better?
Both can rent for $1,500–$3,000/month, but laneway suites may lease faster in urban neighborhoods.
Will neighbors complain?
Garden suites can raise privacy concerns in Toronto backyard homes—add fences or greenery. Laneway suites usually feel more private due to separate access.

My Take: Which One Should You Build?
- Choose a Garden Suite in Toronto or if you’re in Scarborough, Etobicoke, or anywhere without a laneway. It’s budget-friendly, flexible, and faster with pre-fab.
- Choose a Laneway Suite in Toronto or if you’re in a central area with a laneway, want a garage, or need a separate entrance for tenants.
Either way, these suites can increase your home’s value by 10–15% and pay off in under 10 years through rent.
