Garden Suite Toronto provides multigenerational garden suites, detached backyard homes, accessible family suites and lot feasibility reports throughout Scarborough, from Birch Cliff and Cliffside to Guildwood, Agincourt, Highland Creek and West Hill, backed by 20+ years combined Toronto design-build experience.
Scarborough has some of the largest residential lots in the city. That room makes it ideal for full 60 sqm, single-level suites for parents or extended family, as long as lots near Highland Creek, the Rouge and the Scarborough Bluffs are screened for TRCA and ravine rules first.

Local Hurdles
Scarborough Garden Suite Issues: Ravines, Bluffs and Long Service Runs
The most common local problem
Ravine and bluff setbacks on deep family lots
You want a single-level suite for your parents at the back of a long yard, but the rear of the lot slopes toward a creek or the bluffs.
Why it happens here: Highland Creek's watershed covers about 70% of the district and the Bluffs rise up to 90 m above the lake, so many deep lots touch TRCA regulated slopes.
What we do: We screen the slope in feasibility, then site the multigenerational suite where it clears the setback and keeps a step-free path to the house.
Every suite follows By-law 574-2022, Zoning By-law 569-2013 and OBC Part 9. These overlays come up most often on lots here, and we screen for all of them in the feasibility report.
Highland Creek and Bluffs ravines
Lots near Highland Creek, the Rouge and the Scarborough Bluffs may be inside a TRCA regulated area. Slope setbacks can move the suite. We map this in feasibility.
Ravine and Natural Feature Protection By-law
Grading and building near ravine lands needs a ravine review. We confirm what is buildable before design.
Long utility runs
Deep lots mean longer water, sewer and hydro trenches. We price them in the feasibility report so the budget holds.

Housing Stock
What Larger Suburban Lots Mean for a Family Suite
Scarborough's neighbourhoods were mostly built between the 1950s and 1970s, with brick bungalows, back-splits and two-storey homes on lots that are often 50 to 70 ft wide and very deep. Birch Cliff and Cliffside have older homes closer to the Bluffs, while Agincourt, Wexford and Dorset Park have classic suburban grids.
That space is the reason this is our top area for multigenerational suites. A 60 sqm two-bedroom on one level, with a step-free entry, wide doors and a curbless shower, fits comfortably with the required separation from the main house. Our 60 sqm family suite for parents here was delivered at the signed $294,000.
The trade-off on deep lots is distance. Water, sewer and hydro have further to travel from the house, so servicing costs can run higher than on a compact downtown lot. We price the trench length and any Toronto Hydro or Toronto Water upgrade in the feasibility report.
Local Know-How
Deliveries, Fire Access and Permits on Deep Lots
Deliveries arrive via Highway 401, Kingston Road, Lawrence Avenue East and Eglinton Avenue East. Residential streets are wide enough for most delivery trucks and for a crane on prefab-hybrid projects.
Deep lots make the 45 m fire access travel distance the one measurement we always double-check, because a suite placed at the back of a long yard can push the route past the limit. Where it does, we look at siting the suite closer to the house or adding sprinklers.
Permits are reviewed by the Toronto Building Scarborough district office. Our expeditor manages the full application, including TRCA coordination for ravine lots.
Neighbourhoods We Know Well, Bluffs to Agincourt
- Birch Cliff and Cliffside: older homes near the Scarborough Bluffs, where slope and TRCA review matter on lots near the top of bank.
- Guildwood: large treed lots and quiet streets, ideal for accessible family suites.
- Highland Creek and West Hill: deep lots near Highland Creek ravines that need ravine screening before design.
- Agincourt, Wexford and Dorset Park: wide suburban lots with strong demand for family and rental suites.

Soils, Drainage and Fall Servicing
Lots near the Bluffs and Highland Creek can have sandy or variable soils and drainage toward the ravine. We review drainage and grading carefully so the suite does not send water toward slopes. Long service trenches are easiest to dig before the ground freezes, so we aim to complete servicing in fall when a winter start is planned.

Applications here are reviewed by Toronto Building, Scarborough district office. Our in-house expeditor files and tracks every one.

What Toronto Homeowners Say About Working With Us
Feedback from homeowners we have designed, permitted and built for across Toronto. Project prices are the fixed contract amounts.
$418,000 custom 2-bedroom family suite
“Two protected oaks sit behind our house. Their arborist and engineer put the suite on helical piles outside the root zones, and Urban Forestry approved it without a fight. Our son and his kids live out back now, with their own entrance and their own meter.”
$252,000 laneway house rental
“Fire access was the question on our narrow lot. They measured the path, solved it with sprinklers and filed the permit once. The laneway house was rented a week after occupancy.”
$242,000 prefab-hybrid rental
“The report showed our 60-amp panel could not carry a suite. They coordinated the Toronto Hydro upgrade early, so it never held up the build. Rent started in month six.”

What Scarborough Homeowners Ask Us
Local answers on lots, by-laws, permits and costs.
Are Scarborough lots big enough for a garden suite?
Most are. Lots in Agincourt, Wexford and Guildwood are often 50 to 70 ft wide and very deep, which usually allows the full 60 sqm under By-law 574-2022 on a single level. We confirm the envelope in the feasibility report.
Can I build a single-level suite for my parents?
Yes. Scarborough is our busiest area for multigenerational suites. We design single-level, step-free suites with curbless showers, wide doors and a lit path to the main house.
What does a two-bedroom family suite cost?
Most family suites we build here run $240,000 to $340,000, and our 60 sqm two-bedroom for parents came in at $294,000. Long service trenches on deep lots are the main extra cost.
My lot is near Highland Creek. Can I build?
Often yes, with TRCA review. Highland Creek's watershed covers about 70% of Scarborough, so many ravine-edge lots fall inside regulated areas. Slope setbacks may move the suite closer to the house, and we map the regulated area before design.
What about lots on top of the Bluffs in Birch Cliff or Cliffside?
The Bluffs rise up to 90 m above the lake and keep eroding, so lots near the top of bank in Birch Cliff, Cliffside and Guildwood need careful TRCA and slope review. Some are fine; some need the suite placed further from the edge.
Is fire access a problem on deep Scarborough lots?
It can be. The 45 m travel distance from the street is easy to exceed when a suite sits at the back of a long lot. We measure it and site the suite or add sprinklers as needed.
Which permit office reviews these applications?
The Toronto Building Scarborough district office. Our expeditor manages the application, including TRCA coordination for ravine lots, with a 12 to 14 week average.
Is there a tax credit for a family suite?
Many families qualify for the federal Multigenerational Home Renovation Tax Credit. Confirm eligibility with your accountant; we supply the cost documents.
How soon can you look at a deep lot in West Hill or Agincourt?
We usually visit within a week and measure the trench run from the house to the suite on that first visit, since long services drive cost here. The written report follows in about two weeks.
Can a family suite be rented later?
Yes. If family needs change, the family suite can be rented long term under the Residential Tenancies Act.
Still have a question about your lot?
Send us the address and lot width. We will tell you what applies before you pay for anything.
