The Top 3 Considerations for Your Custom Shed's Foundation

A custom shed can be a great addition to your property, providing extra storage space or even a workspace for hobbies and projects. When planning to build a custom shed, it’s important to pay attention to the foundation. The foundation is the base upon which the rest of the shed is built, so it needs to be sturdy and properly constructed to ensure the shed lasts for years to come. Here are the top three considerations for your custom shed’s foundation:

Location and Site Preparation

  1. The first consideration when building a custom shed foundation is the location and site preparation. You need to choose a suitable location for your shed that is level and provides good drainage. A level site ensures that the shed will be stable and prevent any potential problems caused by uneven ground. Good drainage prevents water from pooling around the foundation, which can cause it to weaken and become unstable.

Before building the foundation, you need to prepare the site. This involves clearing away any debris or vegetation, and leveling the ground if necessary. You can use a hand level or a transit level to check for levelness. Once the site is prepared, you can then start building the foundation.

Type of Foundation

2. The type of foundation you choose for your custom shed is another important consideration. There are three main types of foundations: concrete slab, pier and beam, and skid. Each has its own advantages and disadvantages, so it’s important to choose the right one for your specific needs.

A concrete slab foundation is the most durable and long-lasting option. It is made by pouring a concrete pad directly onto the ground. This type of foundation is recommended for larger sheds and those with heavy equipment. However, it can be more expensive and time-consuming to build.

A pier and beam foundation is a good choice for smaller sheds or those built on sloping ground. This type of foundation involves building a series of piers or posts that support a wooden frame. The frame then supports the shed’s floor. This type of foundation is less expensive than a concrete slab and can be built more quickly.

A skid foundation is the simplest and most affordable option. It involves placing wooden skids directly on the ground, with the shed’s floor joists attached to them. This type of foundation is best suited for smaller sheds or those that are only used seasonally. However, it is less durable than the other options and may require more maintenance over time.

Building Codes and Permits

3. The final consideration when building a custom shed foundation is compliance with local building codes and obtaining the necessary permits. Building codes are regulations that specify the minimum standards for construction and safety. These codes vary by location, so it’s important to research the requirements for your area before starting any construction.

In addition to building codes, you may also need to obtain permits from your local government before building your shed foundation. Permit requirements also vary by location and may depend on the size and type of foundation you plan to build. Failure to obtain the necessary permits can result in fines or even legal action.

It’s important to note that building codes and permits also apply to the shed itself, not just the foundation. You will need to ensure that your shed complies with all applicable regulations and obtain any necessary permits before starting construction.


Building a custom shed can be a great way to add extra storage or workspace to your property. However, the foundation is a crucial part of the construction process that needs to be done right to ensure the longevity of the shed. When planning your custom shed, make sure to consider the location and site preparation, the type of foundation you need, and compliance with local building codes and permits. By taking these factors into account, you can ensure that your custom shed will be a valuable and long-lasting addition to your property.
