Building a shed is a very popular project among Quebec homeowners. Whether it's for storing garden tools, seasonal equipment, or creating a small workshop, this outdoor structure offers many possibilities. But before you get started, it's essential to understand the cost of building a shed.
At Plan Maison Québec, we support dozens of such projects each year, and we know that carefully assessing your budget from the outset helps avoid many unexpected costs. In this article, we explain in detail the different factors that influence the cost of a shed in Quebec, with concrete examples and useful tips for planning your project.
1 . The impact of size on cost
The first factor that influences the price of your shed is undoubtedly its size. A small shed measuring 8 by 10 feet, or about 80 square feet, will generally be sufficient for storing garden tools, bicycles, or a few storage boxes. This type of project can remain within a reasonable budget. However, as soon as you go beyond 100 or 150 square feet, costs quickly escalate.
Not only because more materials are required, but also because structural considerations come into play, such as the strength of the walls, the roof's capacity, or the need for a more robust foundation. A 12 by 16 foot shed, for example, is often considered a multifunctional space that can serve as a workshop or mini-garage. This larger size implies a larger budget, especially if you want to integrate electricity, insulation, or other comfort features.
2 . Choosing the right materials to better control your budget
Beyond size, the choice of materials is another determining factor in the cost of your shed. There are several options available, each with its own advantages, disadvantages, and, of course, budgetary implications. It's essential to understand the implications of each material, not only for the purchase price, but also for the durability, maintenance, and overall appearance of your building.
2.1 Wood: charm, quality, but regular maintenance
Wood remains one of the most popular materials for building sheds in Quebec. It blends well with most residential styles and offers a natural warmth that's hard to match. Species such as cedar, treated pine, and hemlock are particularly popular. However, wood requires regular maintenance, including treatments to protect against moisture, insects, and UV discoloration.
Budget-wise, it's often the most expensive option, especially if you choose higher-quality materials and a meticulous finish. However, its high-end appearance and ability to be customized make the investment worthwhile for many homeowners.
2.2 Metal: robustness and affordable price
Metal is often chosen for utility shed projects. It's typically made of galvanized steel or aluminum, which offer good weather resistance, a long lifespan, and very little maintenance. This material is ideal for those looking for a simple, quick, and economical solution. Visually, metal can appear more industrial and offers fewer customization options.
However, for storage sheds installed at the back of the property or in less visible areas, it's an excellent compromise between quality and price.
2.3 Resin and composites: durability and minimal maintenance
Composite materials, such as resin or reinforced plastic panels, have been gaining popularity in recent years. They are waterproof, mold, insect, and fade resistant. They require virtually no maintenance, which appeals to homeowners who want to avoid annual chores.
The initial cost is often higher than metal, but lower or equal to that of quality wood. They are available in a variety of textures and colors, but their customization capabilities are more limited, especially for custom projects.
2.4 Vinyl: an economical but less durable option
Finally, vinyl is an economical option often found on large prefabricated sheds. It's lightweight, easy to install, and inexpensive. However, it's more sensitive to temperature variations and impacts, and its lifespan can be shorter, especially in extreme weather conditions like those found in Quebec.
It's best suited for small, temporary projects or very limited budgets, but it's rarely recommended for long-term construction or projects requiring high strength.
3 . Foundations, roof and location: details not to be overlooked
The foundation of your shed is just as important as its walls. Too often, foundations are overlooked in budget estimates, even though they are essential to the structure's durability. A concrete block foundation may be sufficient for a small, lightweight shed, but it becomes insufficient as the surface area increases or heavy equipment is to be stored. A concrete slab or screw piles are preferred for their long-term stability and strength.
The roof, for its part, must be chosen based on local climate conditions. Asphalt shingles are widely used, but other options, such as sheet metal or membranes, can offer greater longevity depending on the intended use.
As for the location, it may involve additional costs for site preparation, drainage, or leveling, especially if the ground is uneven or difficult to access.
4 . Self-build or contractor: two very different approaches
Building your own shed may seem appealing, especially for those who enjoy DIY. It often saves on labor costs and allows you to adapt the project to your own pace.
However, self-construction comes with its share of challenges: design errors, non-compliance with regulations, cost overruns, and delays are common when you lack the necessary experience. Hiring a qualified contractor not only ensures professional work but also avoids unpleasant surprises.
At Plan Maison Québec, we collaborate with several partners specializing in lightweight construction, who can provide you with durable, compliant, and on-time results.
5 . Price estimates under different scenarios
Here is a summary table based on current standards in Quebec to help you estimate the budget needed to build your shed.
Project | Approximate dimensions | Material / Finish | Total cost estimate |
Small storage shed | 8×10 feet (≈80 sq ft), single metal, single doors, no insulation | Metal, basic roof, minimal window | ≈ 2 000 $ to 4 500 $ |
Medium-sized shed for workshop use or intensive storage | 10x12 feet, wood (standard exterior siding), shingle roof, basic insulation, one window, double door | Wood, simple foundation | ≈ 4 000 $ to 7 000 $ |
Large multifunctional shed | 12x16 feet, higher quality materials (treated wood or composite), insulation, electricity, more doors/windows, minimal interior finishing | Wood or composite, concrete slab, superior finishes | ≈ $7,500 to $10,000 or more |
6 . The building permit application: a mandatory step
In Quebec, the vast majority of municipalities require a building permit for the addition of a shed, especially if it exceeds a certain area (often around 10 or 15 square meters). This requirement is not intended to complicate your project, but to ensure that your construction complies with current urban planning regulations:
lot boundaries
maximum height
foundation type
distance from existing buildings
etc.
The permit application must be submitted to your city's urban planning department. You will often be required to provide a plan of the shed, a sketch of its location on your property, and a technical sheet. At Plan Maison Québec, we support you through this crucial step by providing compliant and comprehensive plans, adapted to the specific requirements of your municipality.
7 . The consequences of non-compliance with municipal regulations
Ignoring urban planning regulations or building without a permit can have serious consequences. In some cases, municipal inspectors may require an immediate halt to work, issue a fine, or even require the shed to be demolished if it is non-compliant. A shed improperly located too close to a lot line, or built with unauthorized materials, can also pose problems if you decide to sell your property.
Furthermore, an undeclared shed can affect your home's insurance value and complicate your claims in the event of damage. For all these reasons, it is essential to comply with municipal by-laws and obtain a permit before beginning construction. This is an aspect we systematically integrate into our support at Plan Maison Québec.
Conclusion : cost to build a shed
Building a shed is a worthwhile and smart investment, but it requires careful planning. From material selection to regulatory compliance, from plan design to choosing a builder, every decision influences the final result and total cost.
At Plan Maison Québec, we believe that a well-managed project is the key to a successful build. Our experts are here to work with you to design custom plans that comply with municipal standards and are tailored to your specific needs.
