How much does it cost on average to build a residential garage in Quebec in 2026?

Building a residential garage is a major investment for Quebec homeowners, with costs varying considerably depending on your needs and choices. Whether you simply want to shelter your vehicle or create a multifunctional space that can be used as a workshop, gym, or storage area, understanding the costs involved will help you plan your budget realistically.

1. General price ranges for building a residential garage in Quebec – The costs of building a residential garage in Quebec in 2026 vary greatly depending on the type of construction chosen. For the shell only, the average cost ranges from $35,000 to $50,000 for a single garage and from $80,000 to $100,000 for a double garage. For a turnkey project, including insulation, electrical work, plumbing, and all necessary finishes, the average cost ranges from $55,000 to $75,000 for a single garage and from $100,000 to $140,000 for a double garage. These costs may vary depending on the region where you live, the contractor you choose, and the specifications of your project.
2. Average building costs based on the most requested dimensions in Quebec – For a 16 x 24-foot (384 sq. ft.) garage that is perfect for one vehicle, the building cost between $20,000 and $75,000 depending on the level of finish chosen. For a 20 x 24 foot (480 sq. ft.) double garage, which is the ideal size for two vehicles, the building cost ranges from $72,000 to $144,000 depending on the level of finish chosen. For a 24 x 30-foot (720 sq. ft.) garage that can accommodate two vehicles and a comfortable workspace or storage area, the building cost ranges from $144,000 to $221,000, depending on the level of finish chosen.
3. Main factors influencing building costs – Floor space is the main factor determining the total building cost. The larger your garage, the more materials and labor you will need, which will increase building costs proportionally. Insulation transforms a simple shelter for parking your vehicles into a space that can be used year-round. An insulated garage also requires a heating system, more elaborate electrical installations, and plumbing. The choice of exterior cladding materials also influences the final price. Vinyl siding is more economical than brick siding, just as an asphalt shingle roof costs less than a metal roof. A garage attached to the house may be slightly cheaper to build since it shares a wall with the main residence. However, it must comply with stricter fire safety standards.
4. Additional building costs to consider – Building permits range from $200 to $1,000 depending on the municipality. Some cities also require soil studies or geotechnical inspections, which can cost between $800 and $2,500. If your garage requires electrical, water, or sewer connections, expect to pay between $2,000 and $8,000 for connections to municipal services. To obtain a building permit, you will need professional plans. Costs vary between $1,800 and $6,000 depending on the complexity of the project and the architect or technologist you choose.
5. Economical options: prefabricated garages – For tighter budgets, prefabricated garages are an attractive alternative. These structures, whose components are manufactured in a factory and then assembled on site, generally cost between $20,000 and $35,000 for a professional-quality model.
6. Tips for optimizing your budget – Obtain at least three detailed quotes from general contractors licensed by the Régie du bâtiment du Québec (RBQ). Prices can vary significantly from one professional to another for the same project. Choose materials that offer the best value for money. Avoid building too small to save money. It’s better to invest in a slightly larger garage from the start than to have to expand it or build a second one later. You can build the basic structure now and add insulation, electricity, or interior finishes later, depending on your available budget.
7. Current market trends – The residential building market in Quebec is experiencing significant fluctuations. Material costs, influenced by inflation and global economic conditions, continue to impact construction prices. General contractors are also facing high demand, which can affect deadlines and rates. Quebec homeowners are increasingly investing in multifunctional garages, which serve not only as parking spaces but also as workshops, home gyms, or optimized storage spaces. This trend partly explains the growing popularity of larger, better-finished garages.

In conclusion, the key to a successful project lies in careful planning, comparing several bids from qualified general contractors, and thoroughly considering your current and future needs. Investing in a well-designed and well-built garage adds significant value to your property while improving your daily quality of life.
