2025 Shed Installation Costs in Ontario

Adding a shed to your property is a great way to increase storage space, enhance your backyard, and even boost your property value. However, many homeowners are curious about how much it will cost to install a shed in Ontario in 2025. The answer varies based on several factors, including the size of the shed, materials, labour costs, and whether you choose professional installation or a do-it-yourself approach.

In this guide, we’ll break down the key cost considerations, compare DIY vs. professional installation, and offer tips on how to get the best value for your investment.

Factors That Affect Shed Installation Costs

Shed installation costs can vary significantly depending on multiple factors. Understanding these elements will help you plan your budget effectively and make the best decision for your needs.

Shed Size and Design

One of the biggest factors influencing shed installation costs is the size of the structure. The larger the shed, the more materials and labour are required, leading to higher overall costs.

Common shed sizes include:

  • Small sheds (up to 64 square feet) – Suitable for storing garden tools, bicycles, and seasonal items.
  • Medium sheds (65 to 120 square feet) – Ideal for larger equipment such as lawnmowers, snowblowers, and patio furniture.
  • Large sheds (120+ square feet) – Often used as workshops, home offices, or additional storage for multiple household items.

The complexity of the shed’s design also affects the final cost. A simple, prefabricated shed is typically more affordable than a custom-built structure with added features like windows, shelving, electrical wiring, or insulation.

Materials Used

The type of material chosen for the shed affects the structure’s cost and longevity. Common shed materials include:

  • Wood sheds are traditional and visually appealing, but they require maintenance. Their prices typically range from $1,500 to $5,000.
  • Metal sheds – A budget-friendly option that is durable and resistant to pests. However, they may be less aesthetically pleasing. Costs range from $500 to $2,500.
  • Vinyl or resin sheds—These sheds are weather-resistant and require little maintenance. They cost between $800 and $3,500.

Higher-end materials, such as composite wood or insulated panels, will increase the overall cost but provide enhanced durability and weather protection.

Labour and Installation Fees

Hiring professionals to install a shed can save time and ensure a sturdy, long-lasting structure. In Ontario, professional installation fees typically range from $500 to $2,500, depending on the complexity of the build.

While a do-it-yourself installation can eliminate labour costs, it requires tools, construction skills, and significant time. Mistakes during the installation process can lead to structural problems, leaks, or uneven foundations, which may result in additional expenses for repairs.

Foundation and Site Preparation

A strong foundation is essential for ensuring a shed’s longevity. The type of foundation required will depend on the shed’s size and weight and the ground conditions.

Common foundation options include:

  • Gravel pad – $200 to $800
  • Concrete slab – $1,000 to $3,000
  • Wooden deck base – $500 to $1,500

Additional costs may apply if your backyard requires additional site preparation, such as clearing trees, levelling the ground, or removing old structures.

Permit Requirements in Ontario

In many Ontario municipalities, building permits are required for sheds over a certain size. In most cases, sheds larger than 108 square feet require a permit, which can cost between $100 and $300.

Permit requirements differ by municipality, so it is always advisable to consult your local building authority before commencing a shed installation project. Failure to secure the required permits may result in fines and legal issues.

DIY vs. Professional Shed Installation

When installing a shed, homeowners must decide whether to handle the project themselves or hire a professional. Each option has its benefits and drawbacks.

DIY Shed Installation

A do-it-yourself approach can be a cost-effective option for those with experience in construction and access to the necessary tools.

Pros:

  • Lower overall costs
  • Full control over the project timeline and design
  • Potential sense of accomplishment

Cons:

  • Requires construction knowledge and tools
  • Time-consuming and physically demanding
  • Higher risk of installation errors

     

If mistakes are made, repairs may end up costing more than hiring a professional in the first place.

Professional Shed Installation

Hiring an expert to install a shed ensures the structure is built correctly, safely, and per local building regulations.

Pros:

  • Expertise guarantees a durable, well-constructed shed
  • Faster installation process
  • Often includes warranties and post-installation support

Cons:

  • Higher upfront cost compared to DIY
  • Scheduling may be dependent on contractor availability

     

Professional installation is the best choice for those who want a stress-free experience and assurance that the job will be done right.

How to Save on
Shed Installation Costs

If you want to install a shed without overspending, there are various ways to reduce costs while obtaining a high-quality structure.

Choose a Prefabricated Shed

Pre-built sheds are often more affordable than custom-built designs. Many home improvement stores offer shed kits to save money on materials and labour.

Install During the Off-Season

Spring and summer are the busiest seasons for shed installations, so prices may be higher due to demand. Scheduling an installation in the fall or winter can sometimes lower labour costs.

Compare Quotes from Professionals

Getting multiple estimates from different shed installation services can help you find the best price. Some companies offer package deals that include delivery, installation, and foundation work.

Select a Simple Foundation

While a concrete slab provides a strong base, a gravel foundation is often a more affordable and sufficient option for smaller sheds. Choosing a simpler foundation can help keep costs lower.

Is Shed Installation Worth the Investment?

Investing in a shed is a great way to improve your property’s functionality, add storage space, and increase your home value. Depending on size, materials, and labour, installation costs can range from $1,000 to $7,500. However, the long-term benefits make it a worthwhile investment.

A well-built shed can serve multiple purposes, from storing gardening tools and outdoor equipment to being used as a workshop, hobby space, or even a small home office. Proper planning, budgeting, and choosing the right materials will help you get the best value for your shed installation project.
