2. Pros And Cons Of A Detached Garage
Before investing in a detached garage, it’s important to evaluate the benefits and potential drawbacks. Here’s a comparison of detached garages versus attached garages:
Pros:
- Customization: Detached garages offer more design freedom, allowing you to customize the garage to the layout of your property without needing to match your existing house.
- Placement Flexibility: Detached garages can be placed based on property lines, topography, and driveway convenience, offering more flexibility compared to attached garages.
- Loft Potential: It’s easier to include a loft or second story in a detached garage, providing extra versatility and space, whether for living or storage.
- Safety: Detached garages keep dangerous carbon monoxide away from your home, providing an additional safety measure.
Cons
- Weather Exposure: The further the garage is from your door, the more exposure you’ll have to inclement weather.
- Cost: The initial cost of building a detached garage may be slightly higher than building attached, mainly because you are building four walls instead of three. However, added work is involved in tying a garage into the house and ensuring there are no leaks.
Overall, the added flexibility of a detached garage often outweighs the cons. Comparing the pricing of attached and detached options is advisable.
3. Pre-Construction Expenses For A Detached Garage
Calculating all potential building expenses is essential. Key pre-construction expenses include driveway and foundation costs.
3.1. Driveway Costs For A Detached Garage
Access to your garage is crucial, and you may need to extend or build a new driveway. Costs vary based on the material used.
| 24×24 Driveway: | Low (Per Sq/Ft): | High (Per Sq/Ft): | Medium Price: |
|---|---|---|---|
| Gravel | $1.00 | $3.75 | $1,440 |
| Asphalt | $3 | $15 | $5,184 |
| Concrete | $4 | $18 | $6,336 |
| High-End | $10 | $40+ | $14,400 |
3.1.1. Cost Of A Gravel Driveway (Cheapest Option)
Gravel is the most affordable option, with prices ranging from $1.00 to $3.00 per sq. ft., though it can cost around $3.75/sq. ft. on the higher end.
3.1.2. Asphalt Driveway Costs
Asphalt is a durable option that requires less maintenance than gravel, with costs ranging from $3-$15/sq. ft. A 24×24 asphalt driveway would cost about $5,184 at the median price of $9/sq. ft.
3.1.3. Concrete Driveway Costs
Concrete offers the most durability but is also more expensive, ranging from $4/sq. ft. to $12 or $18/sq. ft. A 24×24 concrete driveway would cost about $6,336 at $11.00/sq. ft.
3.1.4. High-End Driveway Costs
Luxury driveways using pavers or brick/cobblestone can give an elegant look, with costs potentially ranging from $10/sq. ft. to $40/sq. ft. or more. A 24×24 high-end driveway would cost about $5,760 at $10.00/sq. ft.
3.2. Foundation Costs For A Detached Garage
The foundation is crucial for the stability and longevity of your garage. Costs vary based on the type of foundation used.
| 24×24 | Low Cost | High Cost |
|---|---|---|
| Gravel Pad | $10,000 | $14,500 |
| Concrete Garage Foundation | $6,912 | $20,160 |
3.2.1. Cost Of A Gravel Pad
A gravel pad is a cost-effective and basic foundation, suitable for smaller, pre-assembled garages. A gravel pad for a 24’x24’ garage typically costs between $10,000-$14,500.
3.2.2. Cost Of A Concrete Garage Foundation
For larger projects, a concrete foundation is recommended for durability. Overall, concrete garage foundations can range from $5-$35.
Options for a Concrete Garage Pad:
- Floating Pad: Simple and cost-effective, usually 4” of concrete over 4”-5” of clean stone.
- Floating Foundation: Similar to the floating pad, it includes a 4” floor with a moisture barrier, mesh reinforcement, and footers up to 12” deep.
- Monolithic Foundation: Includes a concrete frost wall about 10” wide descending about three feet underground, optimal for cold climates.
- Block Foundation: 2’ wide footers are poured at frost depth, with a concrete block foundation built on top up to floor height, completed with a 4” concrete floor.
For a 24’x24’ detached two-car garage, a quality concrete floating foundation will be around $4,608 to $8,640, while a garage pad with a block foundation will run from $9,792 to $14,400.
Placing the structure on concrete blocks is discouraged due to potential leveling and settling issues. Ensure your detached garage foundation is built correctly the first time.
3.3. Permit Costs For A Detached Garage
Permits and licenses are essential but not substantial costs. Ensure you factor these into your budget to avoid legal issues.
4. What Are The Costs To Build A Detached Garage?
After addressing pre-construction expenses, it’s time to plan for the actual garage construction. The major components include framing, roof trusses, siding, roofing, garage doors, and interior finishing.
4.1. Framing Costs
The framing is the skeleton of your garage, so quality is crucial. While 2x4s are standard, upgrading to 2×6 framing is advisable for larger garages or when planning to insulate, providing better insulating value.
4.2. Roof Trusses
Roof trusses are commonly used for framing the roof. Numerous options exist, including attic space, stairways, and full second floors, each adding to the cost. A 12” overhang on all sides is a good idea for aesthetics and protection from the elements.
Examples of Truss Options:
- Basic 4/12 Pitch Truss.
- 4/12 Pitch Scissors Truss.
- 10/12 Pitch Attic Garage Truss.
- 12/12 Pitch Truss for Subfloor.
5. What Are The Siding Costs For A Detached Garage?
Choosing the right siding for your detached garage involves considering how it matches existing buildings, durability, maintenance, and budget.

|---|---|---|
| Wood | $3 | $16 |
| Vinyl | $2.50 | $15 |
5.1. Wood Siding
Wood siding sheets, such as T1-11, are an affordable option, with installation costs ranging between $3-10/sq. ft., but can be as low as $2/sq. ft. or as high as over $16+/sq. ft. Proper painting is essential for weather protection.
5.2. Vinyl Siding
Vinyl is popular for its durability, color choices, and low maintenance. Costs typically range from $2.50-15/sq. ft., with the benefit of not needing paint and offering longevity.
5.3. Other Siding Options
Other options include metal paneling, wood shakes, brick, or stucco, each impacting the total cost differently.
6. What Are Roofing Costs For A Detached Garage?
The roof is crucial for protecting your garage. Roofing options include asphalt shingles, corrugated metal, and standing seam metal.

7. Garage Door Costs And Options
Garage doors are essential for access. A standard 9’x7’ door provides good access for most vehicles. Options range from simple, non-insulated metal doors to handcrafted wooden doors.
7.1. Insulated Garage Doors
If you plan to add heat, insulated garage doors are a must, adding to the cost but helping save on heating bills. Consider a reliable garage door opener for convenience.
7.2. Windows And Pedestrian Doors
Include a pedestrian door to avoid opening the main garage door for quick access. Standard widths are 3’ for a single door and 4’-8’ for double doors. Windows are also essential for natural light.
8. Interior Finishing
Customizing the interior of your garage can greatly enhance its functionality and appeal.
8.1. Insulation
Insulating your garage is crucial if you plan to heat it. Options include batt and blanket insulation, loose-fill insulation, rigid foam insulation, and spray foam.
8.2. Electrical, Plumbing, And HVAC
While simple vehicle storage doesn’t require these, electricity for lighting and your garage door opener is essential. Plumbing and HVAC can open up new possibilities for your garage.
8.3. Drywall And Trim
Drywall and paint can enhance the interior, especially if you are finishing loft space or a recreation room.
9. Cost Variations In Building Techniques
Building techniques vary in cost and efficiency. Options include building from scratch, prefab construction, modular construction, and fully constructed.
9.1. Build From Scratch
Building piece by piece ensures complete control over every detail. However, it also adds cost and design complexity.
9.2. Prefab Construction
Prefabricating sections in a dedicated facility maximizes efficiency and reduces on-site construction time. Customers choose a base design that can be customized.
9.3. Modular Construction
Assembling a garage in two major pieces at the construction facility allows for increased efficiency, reducing on-site construction time to less than a day.
9.4. Fully Constructed
For single-car designs, a detached garage can be completely pre-built and transported to your site, reducing on-site time to hours or less and offering the lowest possible price.
