Build Time | 8–14 weeks (factory + on-site assembly) | 6–12 months (weather-dependent) |
Cost per sq. ft. | $250–$350 CAD (includes efficiency gains) | $325–$500+ CAD (varies with labor, delays) |
Design Flexibility | Semi-custom with modular upgrades | Fully custom; unlimited design options |
Energy Efficiency | Factory-sealed, often more airtight; exceeds Ontario Code | Varies by builder; may require upgrades |
Weather Delays | Minimal (factory-built indoors) | Frequent (especially in winter/spring) |
Site Disruption | Lower; shorter time on site | Higher; long-term construction mess |
Permitting Process | Streamlined; pre-engineered plans often pre-approved | Custom plan reviews may take longer |
Inspections | Done at factory + on-site | All on-site, increasing potential delays |
Environmental Impact | Less material waste; energy-efficient transport | Often more waste and variable material sourcing |
Financing Options | May require specialized prefab mortgage or construction loan | Eligible for standard construction financing |
