❌ Mistakes to Avoid When Buying a Modular Home in Ontario
Buying a modular home is a smart move — but like any real estate decision, it comes with potential pitfalls.
Here are the most common mistakes we’ve seen buyers make (and how you can avoid them).
1. Ignoring Zoning & Permits Early On
Some municipalities have strict zoning for ADUs or modular units. Always check local by-laws before placing a deposit.
✅ Tip: Ask your builder to assist with zoning checks or offer referrals to municipal planning consultants.
2. Underestimating Site Preparation Costs
Site work — including grading, utilities, and foundation — can add 15–25% to your total cost.
✅ Tip: Get a full-site assessment before signing off on your budget.
3. Choosing the Wrong Size or Layout
What looks good on paper may feel cramped in real life. Some buyers regret not testing layouts in person or through 3D models.
✅ Tip: Ask for a walkthrough or virtual tour. Our design catalogue includes scaled models and walkthrough options.
4. Over-Customizing Beyond Budget
It’s easy to get carried away with upgrades — but custom features can stretch your budget fast.
✅ Tip: Prioritize must-haves first. Upgrades like solar or smart HVAC can be phased in over time.
5. Not Factoring in Seasonal Delivery Times
Winter and early spring can impact delivery schedules, especially in rural Ontario.
✅ Tip: Order early and plan builds between April and October for best efficiency.
