Cost of Building a Garage: Everything You Need to Know

One of the most common upgrades homeowners make to their properties is the addition of a garage. Not only does it provide a safe and secure place to park your car, but it also offers valuable storage space for tools, equipment, and other personal belongings. However, building a garage can be a significant investment, and it’s important to understand the costs involved before embarking on such a project. In this blog post, we’ll explore the factors that affect the cost of building a garage, average national and regional costs, additional expenses to consider, and ways to save money on your construction project. Whether you’re planning to tackle the project yourself or hire a contractor, the information provided here will help you make informed decisions and avoid unexpected expenses.

Factors that Affect the Cost of Building a Garage

Size of Garage

Size of Garage

The size of your garage plays a significant role in determining the cost of building it. Garages come in different sizes to accommodate different vehicles and purposes. Here are some factors to consider when choosing the right size for your garage:

Single Car Garage

A single car garage typically measures 12 feet wide by 20 feet long, or 240 square feet. This size is ideal for one small to medium-sized car. If you have a larger vehicle or need additional storage space, you may want to consider a larger garage.

Double Car Garage

A double car garage usually measures 20 feet wide by 20 feet long, or 400 square feet. It can accommodate two cars comfortably, but you may need to add a little extra space if you have larger vehicles or a lot of storage needs.

Triple Car Garage

If you have multiple vehicles or need ample storage space, a triple car garage is an excellent option. A typical triple car garage measures 30 feet wide by 20 feet long, or 600 square feet. With this size, you can park three cars or use the extra space for storage, a workshop, or gym.

It’s essential to choose the right size for your garage based on your current and future needs. While smaller garages may be more affordable, they may not provide enough space for your vehicles and storage needs. On the other hand, larger garages may be more expensive, but they offer more flexibility and functionality.

When planning your garage construction project, discuss your size requirements with your contractor to find the best fit for your needs and budget.

Type of Garage

When it comes to building a garage, one of the key decisions you will need to make is whether you want an attached or detached garage. Each type of garage has its own advantages and disadvantages, and choosing the right one for your needs can impact both the cost and functionality of your garage.

An attached garage is connected directly to your home, often sharing a wall. This type of garage is convenient for homeowners who want easy access to their cars and prefer not to walk outside to get to their vehicles. Additionally, an attached garage can add value to your home by increasing its square footage.

On the other hand, a detached garage is a standalone structure that is separate from your house. Detached garages are typically larger than attached garages and offer more flexibility in terms of design and layout. They can also provide additional storage space and be used as a workshop or home office. However, detached garages require more space on your property and may not be as convenient if you need to access your car in inclement weather.

Ultimately, the decision between an attached or detached garage will depend on your personal preferences, budget, and property size and layout. It’s important to consider your current and future needs when making this decision, as well as any zoning or building regulations in your area.

Some things to keep in mind when deciding between an attached or detached garage include:

  • The location of your driveway and how it will connect to the garage
  • The amount of available space on your property
  • The climate in your area and how it may affect your use of the garage
  • Your budget and desired level of customization

By carefully considering these factors and working with a professional contractor, you can select the type of garage that will best meet your needs and help you get the most out of your investment.

Materials Used

Materials Used

When building a garage, one of the most important decisions you’ll make is choosing the right materials. The materials you use will not only affect the overall cost of the project but also the durability and longevity of your garage. Here are some of the most common materials used in garage construction:


Concrete is a popular choice for garage construction due to its strength and durability. It’s also relatively inexpensive compared to other materials and requires minimal maintenance. However, pouring concrete can be a time-consuming process, and it may require permits depending on your location.


Brick is another durable material that gives garages a classic, timeless look. It’s also fire-resistant and low-maintenance. However, brick is generally more expensive than concrete, and it may not be the best choice in areas with seismic activity.


Wood is a versatile and attractive option for garages, offering a warm, natural look that complements many home styles. However, wood is less durable than other materials and can be susceptible to rot, insect damage, and fire. It also requires regular maintenance such as staining or painting to keep it looking good.


Steel has become increasingly popular for garage construction due to its strength, durability, and affordability. It’s also low-maintenance and resistant to pests, fire, and weather. Additionally, steel offers many design options, including different colors, finishes, and textures.

Ultimately, the materials you choose for your garage will depend on factors like your budget, aesthetic preferences, and functional needs. It’s important to consider all of these factors carefully before making a decision. By choosing the right materials, you’ll ensure that your garage is not only beautiful and functional but also built to last.

Labor Costs

Labor costs are a major factor when it comes to building a garage. Hiring licensed contractors for your project can significantly increase the overall cost, whereas choosing to do it yourself (DIY) can save you money but may require more time and effort.

Licensed contractors have the knowledge, experience, and tools necessary to build a garage that is up to code and meets all safety requirements. They also take care of obtaining the necessary permits and may offer warranties for their work. However, the cost of hiring a licensed contractor can vary widely depending on their experience, location, and the complexity of the project.

On the other hand, DIY projects can be more affordable, especially if you have some construction experience or are willing to learn. You will need to obtain the necessary permits and purchase or rent the required equipment and materials. Keep in mind that DIY projects can be more time-consuming and may require more effort and attention to detail to ensure that the garage is built safely and correctly.

It’s important to weigh the pros and cons of each option before deciding which route to take. If you choose to hire a licensed contractor, make sure to get quotes from multiple contractors and ask for references from previous clients. For DIY projects, be sure to research the necessary permits and regulations and invest in quality tools and materials.

In conclusion, labor costs can be a significant portion of the overall cost of building a garage. Whether you choose to hire a licensed contractor or tackle the project yourself, be sure to consider the costs and benefits of each option and make an informed decision.

Average Cost of Building a Garage

When it comes to building a garage, one of the biggest questions on many people’s minds is how much it will cost. While the cost can vary based on factors such as the size and type of garage, as well as the materials used and the labor costs in your region, it’s always helpful to have a general idea of what you can expect to spend.

According to HomeAdvisor, the national average cost of building a garage is around $26,000. However, this number can be significantly higher or lower depending on where you live. For example, in areas with a higher cost of living, the cost of building a garage can be much higher than the national average. On the other hand, in regions with a lower cost of living, the cost can be much more affordable.

Regional cost variations are influenced by several factors such as local regulations and building codes, weather conditions, availability of skilled labor and materials, and more. For instance, if you live in an area that experiences harsh winters, you may need to spend more money on insulation and heating for your garage.

It’s worth noting that these cost estimates are just averages, and actual costs can vary widely based on individual circumstances. The best way to get an accurate estimate of how much it will cost to build a garage in your area is to get quotes from licensed contractors who specialize in garage construction.

Overall, understanding the average cost of building a garage can help you plan your budget more effectively and make informed decisions about your garage construction project. Keep in mind that while saving money is important, it’s also crucial to ensure that your garage is built safely and to code standards to avoid costly repairs or legal issues down the line.

Additional Garage Costs to Consider

When planning to build a garage, many homeowners tend to focus on the cost of the basic structure and overlook other expenses that can quickly add up. Here are some additional garage costs to consider before starting your project:

Permits and Fees

Before breaking ground on your new garage, you will likely need to obtain permits from your local government. Permitting requirements vary by location, but typically involve submitting plans and paying a fee. Failure to obtain the necessary permits can result in costly fines and legal issues.

Site Preparation

Preparing the site for your garage construction is another cost to consider. This may include clearing the land, grading the soil, and laying a foundation. Depending on the condition of your property, this could be a significant expense.

Electrical and Plumbing

If you plan on using your garage as a workshop or living space, you’ll need to factor in the cost of electrical and plumbing work. This may include installing outlets, lights, and heating/cooling systems. If you plan on having a bathroom or kitchen in your garage, you’ll need to budget for plumbing fixtures and connections.

Insulation and Ventilation

Proper insulation and ventilation are important for maintaining a comfortable and safe environment within your garage. This may include adding insulation to walls and ceilings, installing vents or fans, and sealing gaps and cracks. While these costs may seem minor, they can significantly impact the overall comfort and usability of your garage.

By considering these additional costs upfront, you can avoid surprises and ensure your garage construction project stays within your budget.

Ways to Save Money on Garage Construction

When it comes to building a garage, costs can quickly add up. However, there are several ways to save money on construction without compromising on quality or safety. Here are some tips:

DIY Construction

One of the most effective ways to save money on garage construction is by doing it yourself. This may not be feasible for everyone, but if you have experience with carpentry or other construction work, you could save a significant amount of money on labor costs. Keep in mind that certain aspects of the project, such as electrical or plumbing work, may require professional assistance.

Using Affordable Materials

Another way to cut costs is by using affordable materials. While it may be tempting to opt for expensive, high-end materials, there are often more affordable alternatives that offer similar functionality and durability. For example, instead of using traditional hardwoods for framing, consider using engineered lumber which is cost-effective and environmentally friendly.

Negotiating with Contractors

Finally, don’t be afraid to negotiate with contractors. Many people assume that the price they’re quoted is non-negotiable, but this isn’t always the case. By shopping around and comparing quotes from different contractors, you can often find a better deal. Additionally, once you’ve identified a contractor you want to work with, try negotiating on the price or asking them to include additional services at no extra charge.

By following these tips, you can save money on your garage construction project without sacrificing on quality or safety. Remember to plan ahead, do your research, and don’t be afraid to ask questions or negotiate with contractors.
Building a garage is a significant investment that requires careful planning and consideration of several factors that can affect the overall cost. The size, type, and materials used are crucial elements to determine the total expenses of the project, along with labor costs. Homeowners must also consider additional costs like permits and fees, site preparation, electrical and plumbing, insulation, and ventilation.

While building a garage may seem expensive, it can provide long-term benefits like enhancing property value, protecting your vehicle from harsh weather conditions or theft, and providing extra storage space. Homeowners can also save money by choosing affordable materials, DIY construction, or negotiating with contractors.

In conclusion, the cost of building a garage varies depending on several factors, but proper planning and research can help you stay within your budget. By understanding the average national and regional costs, additional expenses, and ways to save money, homeowners can make informed decisions and invest in a functional and secure garage that meets their needs. A well-built garage can increase the value of your home while providing a safe and practical space for your vehicles and other items.
