How Much Does It Cost To Build A 24×24 Garage? (Ultimate Guide)

Did you recently buy an additional car and need to expand or build a bigger garage? If so, you have come to the right place!

Building a new garage can be a costly and complex project. Therefore it is better to get familiar with the prices to estimate the budget you need. Generally, building a garage is between $35 and $ 60 per square foot.

The 24×24 garage is a 2-car garage, meaning it can fit two medium-sized cars, and the approximate cost for the construction of this garage ranges between $19,000 to $28,000.

A 3-car garage is more expensive and costs between $28,000 and $42,000. However, there are different types and styles of garages with varying ranges of prices.

Influencing Factors of Cost of a 24×24 Garage

1. Garage Size

The most crucial factor that you should consider is the garage size. Single-car garages cost between $10,500 to $27,000, depending on the style and type—double-car garages, such as a 24×24, range between $14,000 to $40,000.

Three-car garage costs between $30,000 and $55,000. If you own an RV, you will probably need to build an RV garage, typically costing between $30,00 and $150,000, but the price can even go higher if you need electricity or plumbing.

2. Labor Costs

The next factor to consider is labor costs and the area you live. The prices of garages differ from city to city and, in some cities, can be a very costly project.

For example, the average cost to build a garage in Austin, Texas, is around $45,000, while in Kansas City, Missouri, it is $14,000. Lastly, labor costs make up at least half the total price of building a garage and differ from state to state.

As mentioned, to build a 24×24, contractors usually charge between $35 to $60 per square foot. The 24×24 garage has 576 square feet, which can cost between $20,000 and $28,000.

3. Permit

In addition, some areas in the U.S. require a building permit, so before you start the projects, contact a contractor or a municipal official to see whether you need a permit.

These permits generally cost between $400 to $2,300, while the process to acquire the license can take up several days, so have that in mind.

4. Materials

For example, if you plan on building a garage instead o buying a prefab garage, you will also need to factor in the materials for the construction. The primary construction materials include a concrete slab foundation, cinderblock, wood framing, and roofing.

Many homeowners opt for various luxury add-ons to make the garage more appealing or raise the home’s value. If you wish to install add-ons such as HVAC systems, windows, electricity, and plumbing, that will even further increase the garage construction price.

1. How Much Does The Concrete Slab Foundation Cost?

The building of the garage foundation or the concrete slab will cost you between $5 to $15 per square foot; the total cost is approximately around $3,500 for a 24×24 garage. For a three-car garage, a garage foundation costs around $5,000.

To make a concrete slab, obviously, you will need the concrete, which costs around $140 per cubic yard, poured directly from a mixer truck.

If you are not a contractor or builder, we suggest you leave this to the professional because pouring concrete improperly can cause flooding or drainage issues.

Also, the contractor will tell you what type of concrete slab you need, such as one with T-shaped footing or a frost-protected foundation.

2. How Much is The Garage Roof Installation?

The next expense is roofing, which often breaks the budget. For a 24×24 garage, building or installing a standard asphalt shingle roof can cost up to $5,000. When constructing a garage roof, you will also need a support framework placed on top of the frame.

In most cases, the roof installation includes placing trusses on each end of the support structure, which is then joined by a ridge beam, and later the rafters are added.

The average cost for installing roof trusses is around $4.90/SF. When you put the rafter in place, the next step is to secure the sheet of plywood and add the shingles.

3. What About Garage Insulation?

Depending on the purpose of your garage, you will need insulation or, in simple words, a thick layer of a substance used for thermal management. Different materials can insulate your garages, such as fiberglass, spray foam, glass wool, or natural fibers.

If you have any knowledge about building, insulating, and constructing, you can make this a DIY project and try simple batt insulation. On the other hand, if you have no wish to do this yourself, call a professional.

They generally use blow-in insulation or batt insulation rolls. You can also opt for other types of insulation, such as spayed-in foam, which is a common choice among homeowners.

However, the spray-in foam takes the longest compared to other types because the application means more labor hours and mess.

Generally, insulation is optional, and it also depends on the area where you live. If you live in warmer climates, there is no need for insulation. The average cost for insulating a 24×24 garage is between $1,000 to $3,000 for the labor and materials.

4. How Much Does Garage Framing Cost?

Framing is essential to building a garage, including constructing the wooden framework for your walls and roof.

You must hire a professional for this job because framing ensures that your garage can withstand inclement weather and foundation shifts.

As you probably guessed, the framing is, in most cases, expensive, and the average cost for a 24×24 garage is around $5,000. So, the framing can cost you between $5 to $13 per square foot.

Opting for a bigger garage with different add-ons and intricate designs will cost you even more. The wall framing costs around $7 to $16 per square foot.

However, if you have concrete-poured walls, there is no need for wall framing unless you want to drywall the interior. Framing of the wall depends on the function of the garage. If it has a strictly practical purpose, there is no need to spend extra money.

On the other hand, if you plan to turn your garage into a workshop or an apartment, include the cost of framing interior walls.

5. How Much Do the Windows and Doors Cost?

Garage doors and windows for a 24×24 garage cost between $250 and $550 per window or door. However, the price also depends on the type of windows you want and their style and size. For example, double-pane windows cost more than one-pane windows.

The exterior garage door will cost you more, between $1,000 to $5,000. If you wish to install a skylight, that will cost you between $1,600 to $4,200 in addition to the cost of the window.

6. Do I Need to Install Gutters?

Installing gutters is essential for numerous reasons; besides adding a nice decorative element to your structure, it protects it from water damage, mold, and mildew. So, if you want to build a decent garage, do not skip on gutters!

The average installation price for gutters is between $4 and $8 per linear foot.

7. Do I Need Electricity and Wiring?

Running electricity is a handy and common feature. However, it is not necessary. If you use your garage only to store your car, maybe buying a battery will be cheaper.

However, if you plan to use your garage as a storage space or a workshop, we recommend running electricity in your garage. Finally, the price for electrical and wiring ranges between $6 to $10 per square foot.

8. Detached vs. Attached Garage

There are different types of garages that you can build, but the most common ones are detached and detached garages.

As the name implies, an attached garage is connected to a house, while a detached garage is not and can be installed or built anywhere on your property. The average price for a two-car attached garage is between $14,100 and $41,700.

On the other hand, a two-car detached garage will cost you more, between $19,600 and $28,200.

9. What About the Garage Kit or Prefab Garage?

If you are currently on a tight budget but desperately need a garage, we suggest you buy a prefab garage or steel garage kit.

Those are much less expensive than custom garages and very easy to install; a steel garage kit, on average, costs between $4,000 and $6,500, while prefab garages fall in the $5,000 to $30,000 range.


Building a garage on your property is an expensive project which can cost you between $19,000 and $28,000 for a two-car garage or a 24×24 garage.

As mentioned, the most crucial factors you need to consider are your budget, property size, garage size, labor costs, materials, and permits.

Besides these, there are different add-ons or accessories that you can install or buy for your garage, such as AC, fridge, freezer, storage cabinets, or an additional driveway. However, getting different accessories will increase the overall cost.
