A detached garage is a type of building where cars or vehicles are parked that is separated from a building or a house. This type of garage resembles a modern shed, and unlike garages that are attached to a house, it stands on its own.
How much does a detached garage cost?
- On average, a detached garage is going to cost anywhere from $50 to as much as $125 per square foot, depending upon what type of design is used. A simple 26′ x 26′ garage, for example, can cost anywhere from $40,000 to as much as $85,000, but a smaller garage, as seen in our table below, could be much less. If you decide to double the space and add a two-car garage space, the costs could get closer to $85 per square foot. The cost of a detached garage will depend upon the size, the contractor building the garage, features involved, the complexity of the install and contractor performing the job. Refer to our notes below to see what can affect the costs. Like building a house, there are so many factors that can affect the cost.
- A standard garage with no features such as electricity can cost as little as $50 to $75 per square feet, but if you were to add electrical, shelving, and breezeways, the price can get close to the $70 to $90 per square foot range.
- According to Fixr.com, the price for a detached garage can cost anywhere from $58,432 to $86,400 for a two to four car garage.
- Do It Yourself says if you were to do the job on your own, it would probably cost about $8,500 to $10,000 for a 240 square foot garage, but it could jump if you were to use superior products.
- A prefab detached garage, which can often be found at big box hardware stores such as Home Depot and Menard’s, can cost anywhere from as little as $4,500 for a 12 by 24-foot garage to as much as $25,000 for a 30 by 28-foot garage. This will be for the materials only and won’t include any professional installation. A prefab garage will be a “garage in a box” and will include all the materials, with the exception of a garage door, doors and/or windows. All prefab packages will be different.

What affects the price of a detached garage?
- Where you live: With anything, where you live in the United States can greatly affect the costs. A major city will always be more than a rural subdivision. Also, some zoning boards may stricter guidelines, which may mean you have to invest more into your new garage project.
- The size: This is a no-brainer. As the garage gets larger, the price will, of course, go up because you will need more building material.
- Foundation: The two most popular types of foundation includes a concrete slab or eight-inch block. As we talk about it below, if you need to add a concrete foundation, and you use a professional, it can cost about $5 to $10 per square foot to lay it.
- Siding: Most detached garages will use vinyl/dutch lap siding, and this will all depend, again, on the size of your garage.
- Roofing: This will depend on the pitch of your roof and the type of shingles you use. The higher the pitch, the more you may pay.
- Overhangs: Some owners opt to install a 12-inch overhang on all sides. This can often add a few thousand to the job, depending on the size.
- Garage doors: The size, the type and the number of garage doors can affect the price. An insulated door, for example, can cost more than an un-insulated garage. While rare, some opt to install a framed opening only.
- Entry doors: The same can be said about entry doors. The type and the number of entry doors can affect the price. Common entry doors can include a flush, six-panel, two-panel or a double six-panel.
- Windows: Lastly, like the entry doors, the more windows you add, the more you’re going to increase the price.
What are the extra costs?
- Foundation and excavation work may have to be planned separately outside of the contractor. For foundation work, plan on spending $4 to $10 per square feet.
- Customized blueprints for a garage can cost more if you are unable to find the appropriate standard blueprints online. For example, there are countless blueprint books available that sell for $5 to $50, but again, if you’re unable to find your own blueprints, the costs can be much higher.
- Permits will be required in most counties and cities. Refer to your local city office to get an exact price as well as guidelines in terms of permits. Most permits will be in the $150 to $300 range.
- Roofing, when the structure is done being built, may be an additional charge, but this will all depend on the contractor. If not included, the average square, which covers about 100 square feet, will cost about $100 for just the supplies. The same can be said about the outside siding. Most detached garage builders will use vinyl siding and trim, which can cost about $7 per square installed, so a 1,000 square foot garage could cost close to $7,000 for the siding alone.
- Windows, if added, could be an additional $400 to $1,000 per window, depending on the size and the brand.
- Older structures or garages that have to be knocked down will more than likely require a demolition fee.
- Adding electrical and/or plumbing will all depend on what needs to be done and the complexity of the issue. Most plumbers and/or electricians will charge about $65 to $90 per hour, depending on where you live.
Tips to know
- Always check with your zoning laws before even considering the project as most cities will have strict rules/laws.
