The Cost Of Turning A Carport Into A Garage: With Vs. Without Foundation

Turning a carport into a garage is a popular home improvement project that can increase your home's value and provide additional storage space. One of the key decisions that you will need to make when undertaking this project is whether to build a foundation for the garage or to opt for a foundationless approach. In this post, we will explore the cost of turning a carport into a garage with and without foundation.

Without Foundation

If you choose to convert your carport into a garage without building a foundation, you will save on the cost of excavation, pouring concrete, and other related costs. Here are some factors to consider when calculating the cost of converting a carport into a garage without foundation:

• Framing: The first step in converting a carport into a garage is to frame the walls and roof. This typically involves adding wood studs and trusses to support the roof and walls. The cost of framing a garage without foundation can range from $5,000 to $10,000, depending on the size of the structure and the complexity of the design.
• Siding and Roofing: Once the framing is complete, the next step is to add siding and roofing. The cost of siding and roofing materials can vary depending on the type and quality of materials used. Expect to pay between $3,000 and $10,000 for materials and installation.
• Electrical and Plumbing: If you plan to use the garage for more than just storage, you may need to add electrical and plumbing fixtures. The cost of adding electrical and plumbing can range from $1,000 to $5,000, depending on the complexity of the installation.
• Door and Window Installation: Finally, you will need to install doors and windows to complete the structure. The cost of installing a garage door can range from $500 to $1,500, while windows can cost between $200 and $800 each.

With Foundation

Building a foundation for your garage can provide additional stability and durability, but it will also increase the cost of the project. Here are some factors to consider when calculating the cost of converting a carport into a garage with a foundation:

• Excavation and Site Preparation: The first step in building a foundation for your garage is to excavate the site and prepare the ground for construction. This can involve removing soil, grading the site, and installing drainage systems. The cost of excavation and site preparation can range from $1,000 to $5,000, depending on the size and condition of the site.
• Foundation and Concrete: The next step is to pour the foundation and concrete slab. The cost of foundation and concrete can range from $4,000 to $15,000, depending on the size and complexity of the foundation.

• Framing, Siding, and Roofing: Once the foundation is in place, you can proceed with framing, siding, and roofing. The cost of these materials and installation is similar to the costs associated with a garage without foundation.
• Electrical and Plumbing: As with a garage without foundation, you may need to add electrical and plumbing fixtures to the garage. The cost of these installations is also similar to the costs associated with a garage without foundation.
• Door and Window Installation: Finally, you will need to install doors and windows. The cost of these installations is also similar to the costs associated with a garage without foundation.

Overall, the cost of turning a carport into a garage with a foundation can range from $15,000 to $30,000, while the cost of converting a carport into a garage without foundation can range from $9,000 to $20,000. The cost difference depends on the size of the structure, the materials used, and the complexity of the installation.

It's important to note that the decision to build a foundation for your garage should not just be based on cost alone. There are several other factors to consider when deciding whether or not to build a foundation for your garage. For example, if the ground where you plan to build is prone to flooding, it may be necessary to build a foundation to prevent water damage. Additionally, if you plan to park heavy vehicles or equipment in the garage, a foundation can provide the necessary support and stability.

In conclusion, turning a carport into a garage can provide valuable additional space and increase the value of your home. The cost of this project can vary depending on whether or not you choose to build a foundation for the garage. While building a foundation can provide additional stability and durability, it will also increase the cost of the project. Ultimately, the decision to build a foundation should be based on a variety of factors, including the intended use of the garage, the local building codes, and the condition of the site. By carefully weighing these factors and considering all of your options, you can make an informed decision and create a garage that meets your needs and fits your budget.
