In this guide, we’ll break it all down. You’ll get real numbers, uncover hidden costs, and learn how to avoid common mistakes people make when budgeting for a prefab garage.
By the end, you’ll know exactly what to expect and how to get the best value for your money.
Average Cost of a Prefabricated Garage
Price Range & Square Foot Costs
- In Canada, turn-key detached garages cost between $35 to $60 per square foot, depending on location and finish level. This typically includes site prep, materials, labour, and basic finishes .
- Bare‑bones construction (materials and labour only) tends to run $28,000 to $52,000 for a standard-sized garage
Cost by Garage Type
| Garage Type | Typical Size (sq ft) | Estimated All‑In Price |
|---|---|---|
| Single‑car | ~200–300 sq ft | ~$7,000–$18,000 |
| Two‑car | ~400–576 sq ft | $14,000–$35,000 |
| Larger or Workshop | 600–900 sq ft+ | $35,000–$60,000+ |
- A basic single-car prefab garage built turnkey can cost around $50,000 total (~$240–$300 per sq ft) .
- A two-car prefab garage typically ranges between $35,000 and $60,000, based on finish, insulation, and extras . For a deep dive on pricing a two-car steel garage , check out our detailed guide on how much a 2-car metal garage really costs.
Typical Unit‑Only vs Turn‑Key Cost
- Prefab garage kits (walls, roofing, trusses) often start at ~$10 per sq ft, though final installed cost is much higher .
- Fully installed prefab garage projects in Canada average $35 to $60 per sq ft when sourced from national kits or regional suppliers .
Key Factors That Influence the Price
Building a prefab garage in Canada can cost more or less depending on several key factors. Here’s what really shapes the final price:
Size and Layout
Size is the biggest cost driver. More square footage means more materials and labor. For example, a standard two-car garage (400–576 sq ft) typically falls within the $35–$60 per sq ft range when turnkey including installation . Larger workshops or loft-style garages may cost even more per sq ft.
Materials and Style
- Steel / Metal Frame: Strong and durable but at a premium cost. Kits often run $15–$25 per sq ft, with total installed costs around $100–$250 per sq ft depending on finish .
- Wood or Vinyl structures may be cheaper initially but may require more upkeep over time.
Foundation and Site Preparation
Site prep can add significant cost: excavation ($2,200–$5,200), grading, drainage, etc. Concrete slab foundations with damp-proofing or frost walls can cost $4–$11 per sq ft
Customization & Features
Extras like insulation, windows, doors, electrical wiring, heating, and plumbing raise costs.
Insulation, for example, varies widely in type and price .
Labour and Installation
Hiring professionals vs. DIY makes a big difference. Labour rates vary by region and time of year. Urban regions typically cost more . Prefab kit assembly reduces labor compared to traditional builds.
Delivery and Location
Remote or rural shipping locations may increase delivery fees. Steel prices and local labour costs can also fluctuate by province and season .
Permits and Local Codes
Expect permit fees from $550 to $2,000 , depending on municipality. Zoning, inspection, and compliance can also impact cost .
Prefab Garage vs. Other Garage Options
When exploring garage options in Canada, it’s important to understand how a prefabricated garage compares to other alternatives like custom-built or pole barn-style garages. Each has its own advantages and cost implications.
Prefabricated Garages: The Fast, Cost-Effective Solution
Prefab garages, especially those made from durable steel, are designed off-site and delivered ready for assembly. This approach minimizes labor, reduces waste, and speeds up construction time.
- Typical Cost: $24–$43 per square foot fully installed
- Kit-Only Cost: Around $15–$25 per square foot
- Best For: Homeowners looking for durability, quick turnaround, and predictable costs
Steel prefab garages also come with long-term advantages like low maintenance and high resistance to Canadian weather conditions.
Custom-Built Garages: High Design, High Cost
Custom garages are built from scratch on your property using wood framing or concrete block. They allow for complete flexibility in layout, style, and finishes but at a price.
- Typical Cost: $35–$60 per square foot, or higher in urban areas .
- Timeline: Several weeks to months, depending on weather, permits, and contractor schedules.
- Best For: Homeowners with unique design needs or who want the garage to match an existing home.
While you gain full creative control, you also face longer timelines, more variables, and higher chances of cost overruns.
Pole Barns and Wood Frame Kits: Budget-Friendly, But Limited
Pole barn-style garages and wood frame kits offer a middle-ground solution. They’re more affordable up front, especially in rural areas, but may lack the longevity and insulation of steel structures.
- Typical Cost: $20–$50+ per square foot, depending on materials and finish
- Best For: Agricultural storage, workshops, or seasonal use garages
- Considerations: May require upgrades for year-round use or resale value
Side-by-Side Comparison
| Garage Type | Installed Cost (per sq ft) | Build Speed | Customization Level |
|---|---|---|---|
| Prefab Steel Garage | $24–$43 | Fast | Moderate |
| Custom-Built Garage | $35–$60+ | Slow | High |
| Pole Barn / Wood Kit | $20–$50+ | Moderate | Basic to Moderate |
In short, if you’re looking for a garage that balances price, speed, and long-term durability, prefab steel garages are often the smartest choice especially in Canada’s harsh climate. For homeowners wanting a faster, simpler solution without sacrificing strength or quality, prefab is a clear winner.
Hidden Costs and Considerations
Even with prefab garages, there are extra costs that often surprise first-time buyers. These hidden expenses are just as important as the price per square foot.
Permits and Local Regulations
You’ll usually need a building permit even for detached garages. Fees typically range from $550 to $2,000 , depending on your municipality and project scope . Skipping permits can lead to fines or delays, so plan for this early.
Site Preparation & Grading
Before installation, you may need to clear trees, remove rocks, level the ground, or adjust drainage. Excavation and site prep can cost $2,200–$5,200 . If your lot has slope or poor soil, expect extra costs.
Foundation Upgrades
A simple concrete slab may cost $4‑$11 per square foot, depending on frost walls or waterproof coatings . Engineered foundations cost more but offer better durability especially in regions with freeze-thaw cycles.
Delivery and Logistics
Shipping steel panels or assembled sections can be expensive, especially in remote or rural areas. Costs vary by location, weight, and accessibility. Some providers may add extra fees for long-distance delivery or tricky site access .
Electrical, Insulation & Extras
Adding wiring, insulation, windows, or exterior finishes increases labor and material costs. Electrical work may cost hundreds per outlet or fixture, while premium insulation systems add to base pricing .
Climate-Related Upgrades
In cold Canadian climates, frost-protected slabs, insulation upgrades, and specialized doors are smart but not cheap. These features boost energy efficiency and longevity, especially in winter environments .
Financing & Interest
If you take out a loan or finance, interest charges and origination fees can add up often 5–10% on top of the base price. Knowing your financing terms helps avoid surprises.
Real-World Example (Alberta Focus)
In Calgary, a typical two‑car detached garage ranges from $27,000 to $62,000, averaging nearly $55–$65 per square foot . Many homeowners report spending between $55,000 and $80,000 when including electrical, insulation, HVAC, and high-end finishes .
Summary Checklist: Hidden Costs to Budget For
| Cost Category | Estimated Canadian Range |
|---|---|
| Building Permits | $550–$2,000 |
| Site Prep & Grading | $2,200–$5,200 |
| Concrete Foundation | $4–$11 / sq ft |
| Delivery & Logistics | Varies (potentially high in remote areas) |
| Extras (electrical, insulation) | Hundreds to thousands Dollars |
| Climate-specific upgrades | Additional insulation/frost wall costs |
| Financing / interest | ~5–10% of total project cost |
By planning ahead, you can avoid costly surprises and make sure your prefab garage project stays on budget.
Is a Prefabricated Garage Worth It?
The big question: Is investing in a prefabricated garage a smart move? Let’s explore.
