How Land Costs Shape Prefab Home Prices in Ontario
📅 Last updated: September 10th, 2025
✍️ Written by prefab building specialists at My Own Cottage
Prefab homes are known for being affordable, fast to build, and highly customizable. But one expense many buyers underestimate is the cost of land.
That attractive price you see—like $200 per square foot—usually refers only to the prefab structure. Once you include land purchase, site preparation, permits, and utilities, your total investment can increase dramatically.
This guide explains how land prices in Ontario affect prefab home affordability—and offers practical strategies to manage these costs effectively.
Prefab Home Affordability in Ontario: Beyond the Base Price
Even if your prefab home looks budget-friendly on paper, additional expenses for land, permits, and site preparation can add 30–50% to your final budget.
That’s why choosing the right lot is just as important as selecting the right floor plan. The land you purchase influences:
Your budget (upfront and long-term)
Your timeline for construction
Utility access and municipal approvals
Your property’s future resale value

Rural vs. Urban Land Prices in Ontario for Prefab Homes
Urban centers (Toronto, Ottawa): Expect higher land prices but benefit from easier access to utilities, municipal services, and faster permits.
Rural Ontario (Northern towns, small townships): Land is cheaper, but buyers often face higher site prep expenses and longer approval timelines.
For authoritative housing affordability data, the Canada Mortgage and Housing Corporation (CMHC) and Statistics Canada Housing Data provide updated regional insights.
💡 Example: A client near Sudbury paid 40% less for land than they would have in the GTA. But tree clearing and grading added $20,000 in site prep costs.
On top of this, the home size also affected the price per square foot of their Ontario home.
Prefab Home Land & Site Prep Costs in Ontario (Avg)
| Region | Avg Land Cost | Avg Site Prep |
|---|---|---|
| Toronto (GTA) | $500,000 | $30,000 |
| Ottawa | $350,000 | $25,000 |
| Mid-Sized Cities | $180,000 | $20,000 |
| Northern Ontario | $70,000 | $40,000 |

🔍 The data begs the question as to why prefab home prices are higher in Toronto compared to smaller cities?
Factors Driving Ontario Prefab Land Costs
Location and Proximity to Cities
Toronto & Ottawa: Land demand is high, and lots are more expensive. The advantage is that most already have road access, electricity, and municipal water/sewer.
Northern Ontario: Lots are cheaper but may lack road access or utilities, increasing costs and timelines.
To compare, check our guide on where prefab homes are the cheapest per square foot in Ontario.
Zoning, Permits, and Development Fees
Land is more than dirt—it’s regulated property. Before you build, you’ll need to consider:
Municipal zoning bylaws (lot use, setbacks, building type)
Development charges (can add thousands depending on municipality)
Environmental restrictions (wetlands, heritage land, conservation areas)
📌 With all this in mind, don’t forget to budget for permits and utility hookups beforehand.
Lot Size, Terrain, and Preparation Costs
Even cheap land can be costly to prepare. Factors include:
Site preparation: Tree clearing, blasting rock, grading ($10,000–$50,000+)
Soil type: Clay or unstable soils may require engineered foundations
Drainage: Poor water flow or flood risk can add remediation expenses
