The Cost of Building an Attached Garage in Calgary

Attached garages, which share one or more walls with your home, represent the more economical choice for homeowners seeking to expand their property. The fundamental advantage of attached garage construction lies in shared infrastructure. Because your new garage utilizes existing house framing, foundations, and utilities, you significantly reduce overall expenses compared to building a standalone structure from scratch.

Average Pricing for Attached Garage Construction in Calgary

Throughout Calgary’s diverse neighborhoods, from the deep south to the northwest, homeowners can expect attached garage construction costs ranging from $22,000 to $52,000. When you break this down, the average cost per square foot generally falls between $35 and $50. This price range encompasses both skilled labor and high-quality materials, though the final figure depends heavily on the specific features, insulation levels, and exterior finishes you select to match your existing home.

• Single-Car Attached Garage: For a standard single-car attached garage measuring 12 feet wide by 20 feet deep (240 square feet), you should budget between $7,500 and $12,500. This configuration is perfect for tight lots, accommodating one vehicle comfortably while providing accessible parking directly from your home’s interior. This is a massive perk when carrying groceries during a snowstorm.
• Double-Car Attached Garage: A double-car attached garage measuring 20 feet wide by 20 feet deep (400 square feet) typically costs between $14,000 and $25,000. This size is the most popular choice among Calgary homeowners, offering ample space for two vehicles, basic storage for seasonal gear, and the convenience of covered access.
• Large Double-Car Garage: Some homeowners opt for slightly larger configurations like 24-by-24-foot double-car garages (576 square feet). These projects typically run between $20,160 and $35,280. The extra depth is invaluable if you drive a full-size truck or SUV, or if you simply need extra room for workshop functions or additional storage shelving.

Why Attached Garages Cost Less

You might be wondering why the price difference is so distinct. The 10-15 percent cost savings associated with attached garages compared to detached alternatives stems from several construction advantages:

• Shared Structure: Utilizing existing walls reduces framing, siding, and finishing costs.
• Foundation Efficiencies: Tying into your home’s foundation often lowers excavation and concrete expenses compared to starting fresh.
• Simplified Utilities: Extending power and heat from the main house is significantly cheaper than trenching to a standalone structure.

The Cost of Building a Detached Garage in Calgary

Detached garages (fully independent structures separated from your home) offer unparalleled flexibility in placement, design, and functionality. In many of Calgary’s older neighborhoods with rear lanes, or alleys, this is the standard style. However, this autonomy comes with higher construction expenses. The additional costs reflect the need for independent foundations, complete exterior finishing on all sides, dedicated utility infrastructure, and often more complex permitting processes.

Average Pricing for Detached Garage Construction in Calgary

The cost of building a detached garage in Calgary generally ranges from $25,000 to $79,000, with construction costs averaging $40 to $70 per square foot. This broader price range reflects the greater design variability possible with detached structures. They range from simple storage shells to fully insulated “man caves,” and include the additional foundation, framing, and finishing expenses inherent to standalone buildings.

• Single-Car Detached: A single-car detached garage (12 by 20 feet, 240 square feet) costs between $9,600 and $16,800. This compact configuration works well for properties where yard space is at a premium or where homeowners prefer to maintain clear sightlines from their home to the backyard.
• Double-Car Detached: A standard double-car detached garage (20 by 20 feet, 400 square feet) typically ranges from $16,000 to $28,000. This standard size provides comfortable space for two vehicles and has become increasingly popular among Calgary homeowners seeking protected parking without expanding their home’s physical footprint.
• Oversized Double with Workshop: Larger double-car configurations with dedicated workshop space (24 by 24 feet, 576 square feet) run between $23,040 and $40,320. This is the ideal setup for the hobbyist, creating dedicated areas for vehicle storage alongside hobbies like woodworking, vehicle maintenance, or storing recreational equipment like bikes and skis.
• Triple-Car Garage: For those needing maximum capacity, a triple-car detached garage (30 by 24 feet, 720 square feet) costs between $28,800 and $50,400. This substantial structure provides dedicated parking for three vehicles, a significant workshop or storage space, and the flexibility to accommodate future needs like an electric vehicle charging station or a boat.

Why Detached Garages Command Higher Prices

Detached garage construction involves distinct cost drivers that don’t apply to attached structures. You must excavate and prepare a completely separate building site, requiring professional grading and site assessment to ensure water drains away from both the garage and your home.

The concrete foundation must be engineered independently to withstand frost heaving. Furthermore, detached garages require complete exterior finishing on all four sides. Roofing, siding, doors, and windows are needed for the entire perimeter, substantially increasing material and labor expenses. Additionally, utilities like electrical service must be run independently, often requiring underground trenching and a dedicated sub-panel, adding both material and labor costs to the final bill. Finally, detached garages typically require separate or additional development permits in Calgary, depending on your lot size, coverage ratio, and zoning designation.

Critical Cost Components: Breaking Down Your Garage Budget

Understanding how your garage construction budget allocates across different components helps you make intelligent decisions about where to invest in quality.

1. Foundation and Concrete Slab Costs

In Calgary, concrete slab foundations typically cost $5.50 to $9.00 per square foot, meaning a standard 400 sq. ft. foundation runs $2,200–$3,600. Essential extras like site preparation (excavation and grading) can add $500–$1,500, while reinforcement (rebar/mesh) is highly recommended for durability against Alberta’s freeze-thaw cycles.

2. Framing and Structural Components

Framing generally costs $1.50–$6.00/sq ft for materials and $4.50–$9.50/sq ft for labor. While standard 2×4 studs are cost-effective, upgrading to 2×6 framing allows for better insulation—a crucial investment if you plan to heat your garage.

3. Siding, Roofing, and Exterior Finishes

Exterior costs vary widely based on durability and aesthetics:

• Siding: Vinyl is economical ($3–$4/sq ft), while Hardie board ($8–$10/sq ft) and Stucco ($6–$9/sq ft) offer premium durability.
• Roofing: Standard asphalt shingles cost $2–$4/sq ft, whereas metal roofing requires a higher upfront investment for a 40–50-year lifespan.

4. Electrical and Utility Infrastructure

Basic electrical service runs $800–$1,500. If you are future-proofing, budget an additional $1,200–$2,500 for an EV charging station. For a heated workshop, expect to add $2,000–$5,000 for insulation and heating systems.

Factors That Influence Your Final Garage Construction Cost

Beyond basic size and type, numerous variables impact your project’s final expense, including:

1. Site Conditions and Accessibility

Properties with challenging site conditions, such as poor soil requiring engineered foundations, steep grades necessitating significant excavation and retaining walls, or limited equipment access, inevitably cost more to develop. If your property requires a concrete pump truck to reach the building location because a mixer can’t fit down the side yard, budget an additional $900-$1,200 for this specialized equipment. Similarly, restricted access for the delivery of framing materials may require manual unloading, increasing labor expenses.

2. Calgary’s Climate Considerations

Alberta’s freeze-thaw cycles and significant temperature swings demand special attention to foundation design and waterproofing. Calgary’s frost line extends quite deep, potentially requiring deeper footings than you might see in warmer climates. Additionally, proper drainage and vapor barriers become critical investments to prevent moisture damage.

3. Customization and Premium Features

The base garage cost assumes standard construction. Your final cost increases substantially with lifestyle upgrades:

• Insulated walls and ceilings: Add $1-$3 per square foot.
• Drywall interior finishing: Add $0.75-$2.50 per square foot.
• Heating systems: Add $1,500-$4,000.
• Overhead storage systems: Add $400-$1,500.
• Premium garage doors: Add $600-$1,800 versus standard doors.
• Reinforced flooring for vehicle lifts: Add $500-$2,000.
• Secondary entrance (man door): Usually $300-$600 additional.

3. Contractor Selection and Labor Costs

Labor typically represents 50 percent of your total garage construction budget. Experienced, well-established Calgary contractors like Falcon Contracting Inc. command premium pricing but deliver superior quality, reliability, and warranty coverage. While less experienced contractors may quote lower prices, the risk of construction defects, code violations, or incomplete work often creates expensive problems later.

Calculating Garage Construction Costs in Calgary: A Practical Framework

To avoid sticker shock, it helps to build your budget layer by layer. Start with your preferred garage size and type (e.g., attached single-car, detached double-car) and use the per-square-foot ranges provided above as your baseline estimate.

For example, a 400-square-foot detached double-car garage might initially be estimated at $16,000-$28,000 based on the $40-$70 per-square-foot range.

Next, identify which specific elements will apply to your project:

• Add $500-$1,500 for site preparation and grading.
• Add $300-$800 for development permit (if required).
• Add $500-$1,500 for building and electrical permits.
• Add $800-$2,500 if upgrading to premium exterior finishes (like Hardie board).
• Add $2,000-$5,000 if planning heated, fully insulated use.
• Add $1,200-$2,500 if installing EV charging capability.

This component-based approach typically produces more accurate budgets than simple square-footage calculations, as it accounts for your specific project requirements.
