Types of Garage Conversions We Build in Toronto

Every homeowner’s needs are different, so we offer a wide range of garage conversion services across the GTA:

1. Garage to Bedroom or Guest Suite

Perfect for growing families or multigenerational living. We add proper insulation, heating, egress windows, closets, and flooring so your garage feels like it was always part of your home.

2. Garage to Home Office or Studio

Work comfortably from home with a quiet, insulated, private space. We can add built-in storage, soundproofing, and custom lighting for a productive setup.

3. Garage to Gym

Convert your garage into a personal fitness space. We install durable flooring, mirrors, ventilation, and electrical for your equipment.

4. Garage to Living Room or Family Room

Expand your main floor and create a bright, open living area with modern finishes, windows, and flooring.

5. Garage to Rental Unit / ADU

Toronto zoning allows for garage apartments, garden suites, and laneway suites. We design and build complete units with kitchens, bathrooms, laundry, and separate entrances – built to Ontario Building Code and fire safety standards.

6. Detached Garage Conversions

Detached garages can be converted into standalone living spaces – ideal for garden suites or self-contained guest houses where bylaws allow.

Permits and Legal Requirements Without the Jargons

A common question we hear: “Do I need a permit to convert my garage in Toronto?”

Yes! In almost every case, you’ll need a building permit. The City of Toronto requires one if you’re changing the use of a garage into living space or building a second suite. That includes adding plumbing, heating, insulation, or structural work.

If you’re planning to build a garage apartment or ADU in Toronto, there are strict rules around:

  • Ceiling heights
  • Fire separation between units
  • Smoke and CO alarms
  • Windows and emergency exits
  • Parking requirements

Our team handles the permit process from start to finish. We draw up the plans, submit them to the city, and make sure your project passes inspections. You won’t have to deal with the paperwork.

Thinking about a garden suite or laneway suite from an existing detached garage shell? Toronto’s programs allow additional homes on many lots, subject to criteria like setbacks, height and access. We confirm what fits your property before design.

 

Why Homeowners Should Choose Garage Conversions
(Apart from the Obvious)

There are many reasons families in Toronto and the GTA are choosing to convert their garage into living space:

  • Rental income potential: Convert your garage into a secondary suite or ADU (accessory dwelling unit) and create a legal apartment.
  • Better resale value: Homes with more finished square footage attract more buyers.
  • Lifestyle upgrades: Work from home in a garage-to-office conversion, set up a garage gym, or build a cozy in-law suite.

Put simply: a garage conversion gives you options. You’re not just storing boxes anymore, you’re creating functional, livable space.

What Does a Garage Conversion Cost in Toronto?

Every project is unique, but here are the main factors that affect garage conversion costs in the GTA:

  • Whether it’s attached or detached
  • Adding plumbing for a bathroom or kitchen
  • Heating and insulation upgrades
  • Window and door changes
  • Finishing materials and layout complexity

On average, garage-to-living-space conversions in Toronto are more affordable than a full home addition because you’re working within an existing structure.
