The cost to build a garage in Atlanta averages $24,947, with most homeowners paying from $15,282 to $34,611. We break down some of the main factors that affect how much you’ll pay so you can budget accurately for your new garage.
Garage Building Cost Factors
One of the main questions about building a garage that homeowners ask is how much they should budget for the project. Multiple factors contribute to the cost to build a garage in Atlanta, Georgia, including the garage size, the materials used, add-ons and customization, whether it’s an attached or detached garage, and more. Take a look at some of the things that influence how much you’ll pay.
Size
You'll pay about $43 per square foot on average between labor and materials when working with a professional. However, you'll find prices as low as $26 per square foot for simple, attached garages and up to $102 per square foot for detached, high-end garages with all the bells and whistles.
Below, we've listed the average cost to build a garage by size:
| Garage Size (Sq. Ft.) | Average Cost |
|---|---|
| 12x20 | $6,125–$24,475 |
| 18x20 | $9,175–$36,725 |
| 20x20 | $10,200–$40,800 |
| 20x22 | $11,225–$44,875 |
| 22x22 | $12,325–$49,400 |
| 32x22 | $17,925–$71,825 |
| 32x34 | $19,550–$78,375 |
Materials
Budget-conscious homeowners may choose a lower cost prefab pole barn garage instead of more expensive options like brick or cinderblock, but may sacrifice durability. A stick-built garage that uses the same materials as your home and matches its aesthetics will come in at the top of the cost range, but will be a seamless addition to your property.
| Garage Material | Average Cost (per Sq. Ft.) | Pros | Cons |
|---|---|---|---|
| Brick | $30–$45 | Extremely durable | High initial cost |
| Brick-veneered | $5–$30 | Brick look with lower cost | Susceptible to leaks |
| Cinderblock | $30–$65 | Fire resistant | Prone to cracking |
| Metal | $15–$35 | Resistant to pests, fire, and rot | Noisy during rain or hail |
| Stick-built | $40–$70 | Match home’s aesthetics | Higher cost |
| Prefab pole barn | $11–$40 | Fast installation | Less durable |
Type

The type of garage you build will affect your project cost. A one-car garage will cost less than a multi-car garage, and a detached garage costs more than an attached one, since it’s not built off an existing wall. Here’s what you can expect to pay for some common garage types.
| Type of Garage | Cost to Build |
|---|---|
| One-car | $8,925–$22,950 |
| Two-car | $12,750–$34,000 |
| Three-car | $23,800–$48,450 |
| Attached | $9,175–$55,250 |
| Detached | $12,250–$64,500 |
Permits
Building a garage requires a building permit from Atlanta’s Department of City Planning. Permit fees are $7 per $1000 (or portion thereof) of the cost of construction, so a permit for a garage that costs Atlanta’s average of $24,947 would cost $175. Unpermitted work can lead to fines, citations, stop work orders, and even having to remove the completed work, so ensure you have the proper permits before beginning construction.
Accessibility
If you plan on making your garage more accessible, you may need to hire a local ramp installation pro to install a ramp over the concrete foundation. This may require extra landscaping renovations.
Add-Ons
Adding features to your new garage will add to your final cost. In addition to automatic doors, exterior doors, and windows, budget for the cost to insulate your garage, add security features, or build storage. Adding living space will significantly increase your project cost, but will add valuable square footage to your home.
| Type of Add-On | Average Cost |
|---|---|
| Windows | $300–$2,500 |
| Automatic door | $750–$5,000 |
| Exterior door | $150–$1,400 |
| Insulation | $1,900–$7,700 |
| Storage | $500–$2,200 |
| Security | $300–$2,000 |
| Living space | $125–$250 per sq. ft. |
Garage Builder Costs
Labor costs to hire a garage builder in Atlanta, GA, to construct your new garage will account for 50% to 70% of the total project cost. A qualified and licensed garage builder will manage your project from start to finish, ensure the build meets all local codes and regulations, and coordinate any subcontractors needed to complete the job.
Additional Pros to Consider Hiring
Depending on the specifics of your new garage, you may need to hire additional pros. A structural engineer can review or draw up your garage plans to ensure they’re structurally sound, and they will cost between $200 and $1,500.
Hiring a drywall installer to finish your garage walls will cost $1 to $2.10 per square foot in labor, plus the cost of materials. Depending on the scope of the work, you’ll also need to hire an electrician to install wiring for your automatic garage door, lights, and outlets, which will cost $50 to $100 per hour.
Installing a garage door without prior experience can be extremely challenging and potentially dangerous. It's highly recommended to contact a pro if you need a garage door installed.
Does Building a Garage Increase Home Value?
Building a garage offers a high return on investment (ROI) of 60% to 85%, making it a sound investment in your home’s value. How much value a garage adds depends on the size, type, material, and construction quality, but a new, well-built garage is an enticing feature for prospective buyers and can allow you to ask a higher price for your home when it’s time to sell.
