💡 Cost Factors to Consider When Building
While prefab construction offers major advantages in pricing predictability and speed, your total project budget involves much more than just the base cost of the modular home itself.
Understanding the full cost structure is key to a successful prefab build — especially in Ontario, where regional regulations, terrain, and access play a significant role.
Here’s a breakdown of real-world cost components beyond the home model:
🏞️ Land Purchase & Zoning Requirements
Land Costs: Vary significantly depending on region and water access.
Lakeside lots in Muskoka or Haliburton: $150,000–$500,000+
Rural/wooded inland lots: $70,000–$200,000
Zoning Compliance: Confirm zoning allows for permanent residential use, not just seasonal.
Ontario Building Code (OBC): Ensure your prefab meets municipal requirements, including snow load, height limits, and minimum setbacks.
🛑 Tip: Always conduct a zoning and conservation authority check before purchasing land to avoid costly delays.
🔧 Site Preparation & Services
Foundation & Excavation:
Typical slab or crawlspace: $10,000–$30,000
Basement (optional): $35,000–$60,000+
Utility Hookups:
Septic system: $12,000–$18,000
Hydro, water, propane tanks: $8,000–$15,000
Access Road / Driveway Construction:
Up to $10,000–$20,000 for remote or sloped lots
✅ All these steps must be completed before modular delivery and are often not included in base builder quotes.
🧱 Customization, Materials & Energy Efficiency
High-quality upgrades like:
Floor-to-ceiling windows for natural light
Metal roofing, composite siding, or board-and-batten exteriors
ENERGY STAR® HVAC systems or radiant heating
These add $20,000–$60,000+ depending on scale
🌱 Investing in energy-efficient upgrades not only enhances comfort but also lowers long-term energy consumption — especially important for remote or off-grid cottages.
🚛 Delivery & On-Site Installation
Delivery Costs: $5,000–$15,000+ based on:
Distance from the factory
Size of modules and site accessibility
Use of barge, crane, or staged installation
Savings Tip: Opting for off-peak delivery (spring/fall) to reduce logistical surcharges
📜 HST & Building Permits
HST (13%): Applies to most prefab builds in Ontario, including both the structure and on-site work
Municipal Building Permits: Range from $2,000 to $5,000, depending on project scope and region
🛡️ Ensure your builder provides a detailed scope of work and discloses tax treatment upfront to avoid surprises.

How to Save on Your Prefab Cottage Build
Smart planning leads to major savings.
We heard this from Ontario prefab builder Karen Liu who shared these insights:
“The biggest savings come from reusing modular floorplans and building in the off-season. Winter builds avoid high summer freight and installation costs.”
Key Money-Saving Tips:
Choose modular platforms or pre-designed floorplans
Buy off-peak (late fall/winter)
Consider cottage shells for DIY interiors
Partner with a builder who handles zoning/permitting
Opt for compact footprints (<900 sq ft) for efficiency
