Garden Suite Toronto provides garage conversion suites, rental income garden suites, laneway houses and detached suites from North Riverdale and Playter Estates to South Riverdale, Broadview and the Danforth, backed by 20+ years combined Toronto design-build experience.
Riverdale's rear garages and tenant demand make garage conversions and rental suites the most common projects here. We assess whether your old garage can become a permitted suite, or whether a rebuild or laneway suite gives more space for the money.

Local Hurdles
Riverdale Garden Suite Hurdles: Old Garages, Heritage and Fire Access
The most common local problem
A tired lane garage on a Victorian lot
An old garage at the back of the lot is failing, and you have heard a new building would need bigger setbacks than the old one.
Why it happens here: Most homes here are Victorian and Edwardian, built in the 1800s, and part of the area is a Heritage Conservation District designated in 2008, so both setbacks and design get a close look.
What we do: We assess the slab and walls, then compare a garage conversion that keeps legal non-conforming setbacks with a rebuild or a laneway 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.
Legal non-conforming garage setbacks
Old garages often sit closer to lot lines than current rules allow. Keeping the structure may keep that status; a full rebuild may not.
Narrow lots and fire access
Shared side paths must stay 1 m clear for the whole route within 45 m. Sprinklers can help when they cannot.
Old services
Galvanized water lines and small electrical services are common and usually need Toronto Water or Toronto Hydro upgrades.

What Victorian Lane Lots Mean for a Garden Suite
Riverdale was built mostly between 1880 and 1920: Victorian and Edwardian semis and detached homes along Broadview, Logan, Pape and the streets around Withrow Park and Riverdale Park. Lots are typically 18 to 30 ft wide and deep, and many back onto public lanes with old detached garages at the rear.
Those garages are an opportunity. When the slab, footings and walls are sound, converting the garage can be the lowest-cost route to a permitted suite, and it may keep legal non-conforming setbacks that a new building would not get. Our 38 sqm garage conversion on a Victorian lot was delivered for $168,000. In Playter Estates, we kept an old garage slab, rebuilt the walls and roof and created a bright suite for $206,000.
Where the garage is too small or failing, a rebuild, a laneway suite or a detached garden suite may give more space. On the Danforth, a 60 sqm two-storey suite with a loft office came in at $362,000.
Local Know-How
Lanes, Deliveries and Old Services
Riverdale's lanes are the key to logistics. On lane lots we bring materials in from the rear, keep bins tidy and schedule work so neighbours can use their garages. Streets off Broadview Avenue, Logan Avenue, Pape Avenue and Gerrard Street East have permit parking and streetcar traffic, so deliveries are early and small.
Narrow lots and shared side paths make the 45 m fire access route and 1 m clear path a common issue. Sprinklers can solve it when the route is too tight.
Many homes here still have small electrical services and old galvanized water lines. We check both on the first visit. Permits go through the Toronto Building Toronto and East York district office.
Streets We Know Well, Playter Estates to Gerrard
- Playter Estates: larger Edwardian homes and garages that suit conversions or rebuilds.
- North Riverdale near the Danforth: strong rental demand and lane lots that can take two-storey suites.
- South Riverdale near Gerrard: narrow Victorian semis where fire access and the 40 sqm cap are the main tests.
- Streets around Withrow Park and Riverdale Park: mature trees that need arborist coordination.

Slabs, Lanes and Winter Close-In
Converting a garage means working with an old, often uninsulated slab. We plan slab work and insulation before winter so the floor stays dry and warm. Lanes are not always plowed, so lane-access projects aim to close in before snow. Neighbouring garages close to the lot line get a pre-construction condition survey.
Permit office
Applications here are reviewed by Toronto Building, Toronto and East York 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.
$264,000 detached 1-bedroom rental
“Our house still had a half-inch galvanized water line. The feasibility report caught it, and they had Toronto Water booked before the permit even landed. No surprise bill, no lost month. Our tenant moved in on the date we planned in January.”
$356,000 custom suite with loft
“I am downsizing into the suite and my daughter's family takes the house. The design team gave me one level for living and a loft for guests, with step-free entry and a lit path to the back door. Every draw matched the schedule we signed, and the 10-year warranty transfers if we ever sell.”
$288,000 detached garden suite
“They gave us the written feasibility report inside two weeks. The variance we needed for the TRCA ravine lot was flagged before we spent a dollar on drawings. Permit cleared in 11 weeks. Suite ready for tenants in month 7.”

Riverdale Garage and Garden Suite FAQs
Local answers on lots, by-laws, permits and costs.
Can I convert my Riverdale garage into a suite?
Often yes, if the slab, footings and walls are sound and the garage is big enough. It becomes a garden suite or laneway suite and needs a change of use permit. We assess the structure and zoning status first.
Is it better to convert or rebuild my garage?
It depends on the slab, height and size. Converting is cheaper when the structure is sound; rebuilding can add space. Our report compares both with prices.
What does a garage conversion cost?
Most conversions here run $120,000 to $220,000. Our 38 sqm conversion was $168,000, and a Playter Estates rebuild on the existing slab was $206,000.
Can my lane garage become a laneway house?
If the lot fronts a public lane, a laneway suite under Chapter 150.8 may be possible and can sometimes be taller or larger than a conversion. We model it in feasibility.
Do suites near the Danforth rent well?
Yes. Demand near Broadview, Chester and Pape stations on Line 2 is strong, with rents typically $2,300 to $3,200 a month.
Is my street in the Riverdale Heritage Conservation District?
Possibly. Part of Riverdale was designated a Heritage Conservation District in 2008, and suites inside it need heritage review alongside the permit. We check your address against the district boundary in feasibility.
Will my Victorian semi need service upgrades?
Many homes built here in the 1800s still have galvanized water lines and small electrical services that need upgrading for a second unit. We check and coordinate them early.
How do firefighters reach a suite behind a semi?
Shared side paths between semis must stay 1 m clear for the full route within 45 m of the street. If a fence or meter narrows the path, sprinklers or another alternative solution may work.
Can I keep my garage's existing setbacks?
Sometimes. If the garage has legal non-conforming status and the structure stays, some setbacks may carry over. We confirm before design.
How soon can you inspect an old lane garage?
Usually within a week. We check the slab, footings and walls on that first visit, and the written feasibility report follows in about two weeks.
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.
