Frequently Asked Questions
How long does custom home building take in Toronto? Typically 12–24 months total, with 2–6 months for permits alone. Weather and supply chain issues can extend timelines.
What’s the difference between custom and semi-custom homes? Custom homes are built 100% from scratch to your specifications. Semi-custom uses a builder’s existing floor plan with modification options.
Do I need to hire a separate architect? Many Toronto builders offer design-build services, handling both design and construction. This often saves time and money while ensuring better coordination.
What is HCRA licensed and why does it matter?
HCRA (Home Construction Regulatory Authority) licensing ensures your builder meets Ontario’s professional standards for home construction. Licensed builders must carry proper insurance, follow building codes, and provide warranty protection. Using an unlicensed builder puts you at risk for substandard work, no legal recourse, and potential liability issues.
Can I build a laneway home on my property? Only if your property meets Toronto’s laneway housing requirements: minimum 3.5m wide laneway, adequate rear yard space, and proper zoning.
Design-Build vs. Separate Teams
Design-Build Firms (Recommended for most)
Pros: Single point of contact, better coordination, often more cost-effective, faster timeline Cons: Less flexibility in architect selection
Separate Architect + Builder
Pros: Maximum creative freedom, can select top specialists Cons: Higher costs, more coordination required, potential for miscommunication
Contract Essentials & Protection
Your contract must include:
- Detailed scope of work with material specifications
- Itemized budget with allowances clearly defined
- Payment schedule tied to completion milestones
- Timeline with delay clauses and penalties
- Change order procedures and pricing
- Warranty terms and dispute resolution process
Pro tip: Have a construction lawyer review any contract before signing.
Verifying Your Builder’s Legitimacy
Step-by-step verification:
- Search builder for registration status
- Check Google Reviews for ratings
- Request and contact at least 3 recent client references
- Tour completed homes from the last 12 months
- Verify business registration through Ontario’s Business Registry
