How Much Does It Cost to Build a 20×20 Shed?

Building a 20×20 shed can be a great solution for those in need of extra storage space or a dedicated workspace.

However, before getting started on this project, it’s important to understand the associated costs involved.

There are various factors that can affect the cost of building a 20×20 shed, including material choices, labor costs, permits and regulations, and more.

The average cost of building a shed that is 20×20 is around $4000.

Material Choices and Their Effect on Cost

One of the most significant factors to consider when building a 20×20 shed is the choice of materials. The three most common materials for shed construction are wood, metal, and plastic, each of which has its own set of advantages and disadvantages.

Wooden sheds are perhaps the most popular choice due to their durability and classic appearance. However, they can be more expensive than other options, and require regular maintenance to prevent rot and decay.

Metal sheds are another popular choice, with the advantage of being low-maintenance and long-lasting. They are also a good option for those in areas with high wind or snow loads. However, they can be more expensive than plastic sheds and may not be as visually appealing.

Finally, plastic sheds are the most economical option, with the added benefit of being resistant to rot and decay. However, they may not be as sturdy as other options and may require extra insulation for protection against extreme temperatures.

Other factors that can affect the cost of shed materials include the quality of the materials, the complexity of the design, and the size of the shed. Ultimately, it’s important to choose materials that meet both your aesthetic and functional needs, while also fitting within your budget.

Labor Costs: Professional Builders vs. DIY Projects

Another significant factor to consider when building a 20×20 shed is the cost of labor. Hiring a professional builder will typically result in higher costs, but can ensure a correct build and faster completion time. However, if you have the skill and experience with tools, you may be able to save money by doing the work yourself, or taking on the project as a DIY.

The average labor costs for building a shed can range from $50 to $100 per hour, depending on the complexity of the project and the experience of the builder. You will need to factor in these labor costs when estimating the total cost of your 20×20 shed, as they can significantly impact your budget.

Additionally, if you plan to make several trips to your local hardware or home improvement store, it’s important to include those extra costs in your project spending. Building a shed can be time-consuming, but it can also be a rewarding project that results in substantial cost savings compared to hiring a professional builder.

In the next section, we’ll explore the permits and regulations that must be considered when building a 20×20 shed.

Cost Factors

The average cost of building a 20×20 shed is between $3,000 and $5,000 for materials and labor, not including permits or other associated costs. The material you choose will affect the overall cost, with wood being the most expensive but longest-lasting when properly maintained. Metal and plastic sheds are usually less expensive but may not be as durable as wooden sheds.

Labor costs are another factor to consider. If you hire a professional builder, the cost will be higher, but they will ensure a correct build. On the other hand, if you are skilled with tools and have some experience building, you may be able to turn it into a DIY project and save on labor costs.

Permits and regulations are necessary for construction and can cost anywhere from $50-$500+. The paperwork involved can be tedious, but it’s important to understand your jurisdiction’s regulations before beginning construction. Failure to do so could result in fines or other penalties.

Permits and Regulations: What You Need to Know

Before embarking on any shed-building project, it is important to understand the permits and regulations necessary in your jurisdiction. Building codes vary by location, so it is essential to do your research and obtain the necessary paperwork before beginning any construction.

The cost of permits can vary widely, ranging from $50 to $500 or more, depending on your location and the scope of your project. It is essential to read the fine print and understand all requirements before beginning construction to avoid any unforeseen costs.

Additionally, building a pathway can help protect your shed. Clearing an area and building a pathway to your shed can also ensure easy access while preventing damage to the surrounding landscape.

When it comes to the complex legal paperwork and jurisdictional regulations involved in building a backyard shed, a professional contractor can be a valuable asset. While hiring a pro to install your shed can add to the project spending, their expertise can be invaluable in navigating regulations and ensuring a sturdy, safe structure.

However, if you’re up for the challenge, building a shed can be a rewarding and enjoyable DIY project. There are many kits available with all the necessary parts and instructions you need to make it a success. And, of course, the cost will be much lower if you install yourself.

In any case, understanding permits and regulations is necessary knowledge for any shed-building project – no matter whether you opt for a professional builder or decide to turn it into a DIY project.

Tips for Affordable and Successful Shed Building

Building a 20×20 shed can be cost-effective if done correctly and with proper planning. Here are a few tips to help you achieve your goals within your budget:

1. Choose the right material – Consider the lifespan of the material and how much maintenance it will require.

2. Optimize space – Plan the interior of the shed carefully to maximize storage or entertainment options.

FAQ – Cost Of Building a Shed

Is it cheaper to build a shed or buy one?

The cost comparison between building a shed and buying one largely depends on the materials, labor, and customization options involved.

Building a shed typically offers more flexibility in design and can be more cost-effective if you have the skills and time to construct it yourself.

However, purchasing a pre-built shed can save time and effort, but might cost more, especially if you choose a higher-quality material or require additional customization.

How much does Lowes charge to build a shed?

Lowes offers a variety of shed options with different prices depending on the size, material, and style.

A 20×20 shed from Lowes can range from $2,000 to over $10,000, with installation fees varying based on the complexity of the project.

It is recommended to contact your local Lowes store for a more accurate estimate of the total cost to build your desired shed, including labor and any additional features.

Do you need a foundation for a shed?

A solid foundation is essential for the stability, longevity, and overall performance of your shed.

A proper foundation helps to distribute the weight of the structure evenly, prevents moisture from seeping in, and protects the shed from shifting due to ground movement.

Common types of shed foundations include concrete slabs, pier and beam, and gravel pad foundations.

The choice of foundation depends on your shed’s size, intended use, and local building regulations.

Can I just put a shed on the ground?

Placing a shed directly on the ground without a proper foundation is not recommended.

This can lead to several issues, including moisture damage, ground movement, and an unstable structure.

Over time, the lack of a suitable foundation can cause your shed to sink, shift, or become damaged, leading to costly repairs or even replacement.

It is crucial to invest in a proper foundation to ensure the durability, safety, and longevity of your shed.


In conclusion, building a 20×20 shed can be an affordable and rewarding project if it’s done correctly.

Proper planning, understanding all cost factors, and taking advantage of prefabricated kits can save you money and result in a visually pleasing structure.

Choosing the right materials, understanding regulations, and having a solid foundation are crucial in building a structure that will last for years to come.

With these tips in mind, you can achieve your goals and add extra space to your home or backyard.
