Converting Your Garage into a Studio, Work Space or Gym: What to Know

You’ve got a garage in Toronto that’s not exactly earning its keep. Maybe it’s a storage zone full of hockey gear and tires, or perhaps a hiding spot for the neighbourhood raccoon. Why not transform that underused area into valuable living space? Many homeowners in Toronto’s older neighbourhoods, from East York to Leslieville and the Beaches, are realizing their garage can become so much more than a place to park (if they’re even doing that). 

Converting your garage into a studio, home office, or personal gym can drastically expand your usable space without expanding your home’s footprint, all while adding character and functionality to your property. Here’s what you need to know about turning your garage into your new favorite room.

Why Convert Your Garage into a Studio or Gym?

Converting a garage is an opportunity to repurpose your living space without increasing square footage. Instead of moving or building an addition, you can repurpose what you already have. By renovating the existing shell, you might avoid the costs and red tape of new construction while still gaining a whole new room. In terms of resale value, a finished multi-purpose space can prove a desirable feature to Toronto residents in the market. 

Do You Need a Permit to Convert a Garage in Toronto?

The short answer is probably yes. Turning a garage into an interior living area counts as a major renovation, which means complying with building codes and getting permits in many cases. Garage conversions are generally legal in Toronto, provided that you attain the correct regulatory permissions. 

A building permit is typically required for changes like insulating walls, altering the doorway, or adding plumbing and electrical outlets. If you plan to include a bathroom or kitchenette, additional plumbing and electrical permits will be needed as well. It’s crucial to follow the Ontario Building Code and Toronto zoning bylaws to ensure the space is safe.

What About Zoning?

If your garage is detached, converting it purely for personal use like a studio, gym, or workshop, is usually straightforward with a permit. However, if you intend to create a separate rental suite or garden suite, you’ll have to meet additional requirements for a legal secondary unit. Also note that if your garage is very close to the property line, there are rules about adding windows. 

Don’t let these details scare you off. A good contractor will navigate the red tape for you. At D2 Build, for instance, we can handle all permitting and ensure designs meet Toronto’s building codes, so you can focus on the fun part: planning your new space.

How to Make a Garage Livable and Comfortable

How to Make a Garage Livable and Comfortable

Insulation

As with any living space, you want to insulate the floor, walls, and ceiling of the garage to maintain comfortable temperatures and improve energy efficiency. This might include installing insulation boards on the walls and spray foam or batts in the ceiling. Many older garages sit on an uninsulated slab. Consider raising the floor height by adding a subfloor with insulation; this not only warms up the space but also removes that awkward step down from the main house.

Heating and Cooling

To use your new studio year-round, plan for climate control. The most popular solution is a ductless mini-split HVAC unit, which provides efficient heating in winter and cooling in summer. It operates independently from your home’s furnace, ideal for a detached garage. In-floor radiant heating is another luxury touch. Either way, a comfortable temperature will make the garage feel like an extension of your home, not an afterthought.

Upgraded Doors and Windows

Traditional garage doors tend to be uninsulated and leaky, letting in drafts and moisture. You can retrofit the existing door with an insulation kit and weather stripping, replacing it with an insulated modern garage door, or go all-in and swap it for a wall with sliding glass doors or French doors. Many homeowners transform the look of the space to bring in natural light. 

Electrical and Lighting

In a garage conversion, it’s common to upgrade the electrical panel or add a subpanel to handle the increased load. Consider LED pot lights on the ceiling and maybe stylish pendants or floor lamps for ambiance. If you’re doing an art studio, you might add track lights to illuminate your work. Always use a licensed electrician.

Walls, Floors, and Finishes

To banish the “garage feel,” finish the interior similar to any room. Finished drywall not only looks better than bare studs or concrete, it also adds a layer of fire protection and helps with climate control. For the floor, choose a durable finish. Add baseboards, paint the walls with your favourite colours, and voila – it’s a real room! If the space will be closed up, you might need an exhaust fan or at least windows that open, especially for a workout area or workshop where fumes or sweat might accumulate.

Creative Ideas for Your Garage Conversion

Home Gym

A garage is ideal for a personal fitness studio. Many Toronto homeowners have made this change. You can install rubber flooring for shock absorption, wall mirrors to check your form, and mount a TV or sound system to keep you motivated. With the garage door replaced by insulated walls or glass, your gym will be warm in winter and cool in summer, especially if you’ve got it climate controlled.

Art Studio

A converted garage makes a fantastic creative studio. You get separation from the main house so paint fumes or loud sounds won’t invade the living room, and plenty of room to spread out your canvases or instruments. To design a great art studio, focus on light. Add skylights or large windows if possible.

Music Studio

For a music studio, consider soundproofing measures like insulated drywall and acoustic panels on walls. Built-in storage for recording gear will help keep the space organized. It’s your private creative haven right at home. 

Home Office 

Despite back to office requests, home offices are still highly popular and practical.  A private work area separated from the distractions of the main house can be tailored to your work style. Bring in natural light and finish it with comfortable flooring and maybe even some built-in bookshelves. 

Guest Suite

By adding a small bathroom or kitchenette, you could host out-of-town guests in comfort or give your teenager their own space. Keep in mind that creating a full secondary suite may require additional permits, but a cozy guest space for personal use is doable. 

Does Removing A Garage Limit Resale Value?

In some neighbourhoods where parking is limited, eliminating your garage could be a downside at resale time, whereas gaining an extra finished room might increase your home’s value. It’s all about finding the right balance for your situation.

  • Playroom
