What Our Clients Say About Our Services
Frequently Asked Questions
Which renovations add the most value to a home?
In the Toronto market, the highest Return on Investment (ROI) comes from projects that increase functional square footage or improve energy efficiency. Key renovations include:
- Legal Basement Suites: Adding a rental suite or secondary dwelling unit is the top value-adder due to Toronto’s high housing demand.
- Kitchen Refreshes: Minor to mid-range updates (new counters, cabinet refacing, and energy-efficient appliances) typically outperform major luxury guts.
- Bathroom Upgrades: Modernizing fixtures or adding a second bathroom to a single-bath home significantly boosts resale appeal.
- Energy Efficiency: Upgrading to heat pumps, triple-pane windows, and high-performance insulation is increasingly attractive to buyers facing rising utility costs.
- Curb Appeal: A new front door, professional landscaping, or updated siding offers a high impact for a relatively low investment.
How much does a home renovation cost in Toronto?
In 2026, a full house renovation in Toronto typically costs between $150 and $450 per square foot, depending on the age of the home and the quality of finishes. For a standard 1,500 sq. ft. detached home, homeowners should budget between $200,000 and $600,000+.
The cost is generally broken down into three tiers:
- Basic/Cosmetic ($150–$200/sq. ft.): Best for updates like painting, new flooring, and mid-range kitchen/bath refreshes without moving walls.
- Mid-Range ($200–$350/sq. ft.): Includes layout changes, custom cabinetry, upgraded electrical/plumbing, and high-quality materials (quartz, hardwood).
- High-End/Full Gut ($350–$500+/sq. ft.): Involves structural alterations, luxury finishes, smart home integration, and modern energy-efficiency upgrades (Tier 3 standards).
Local Tip: Don’t forget to factor in the 13% HST, City of Toronto permit fees (which can range from $2,000 to $10,000+ for major work), and a 15% contingency fund for the “hidden surprises” common in older Toronto properties.
How long does a home renovation take?
The timeline for a Toronto renovation depends on the scope of work and the City’s permit approval speed. On average, you should budget for the following timeframes:
- Cosmetic Refresh (1–2 Months): Best for surface-level updates like painting, new flooring, and lighting.
- Kitchen or Bathroom Remodel (3–5 Months): Includes design, ordering custom cabinetry (8–12 week lead times), and construction.
- Basement Finishing (4–6 Months): Standard finishing is relatively quick, but adding a legal secondary suite or underpinning can extend this significantly.
- Full House Gut / Major Addition (9–15+ Months): These large-scale projects require extensive architectural drawings and structural permits.
The “Toronto Factor”: Budget 3–6 months before construction for design and City of Toronto approvals. If your project requires a Committee of Adjustment hearing for zoning variances, add an additional 3–5 months to your pre-construction phase.
How should I prepare for a renovation while living in the house?
Living through a renovation is a test of patience. Depending on what parts of the house you are renovating, we recommend:
- Setting up a “Mini-Kitchen”: Move your microwave and coffee maker to a clean room.
- Decluttering: Move all furniture and breakables out of the work zone.
- Dust Protection: Ensure your contractor uses plastic sheeting and HEPA filters.
What are the most common renovation mistakes?
These are some of the most common mistakes customers make when renovating their homes. Avoid these frequent pitfalls to keep your project on track and under budget:
- Skipping the Contingency Fund: Unexpected issues like mold or faulty wiring often hide behind walls. Always set aside an extra 10–20% of your budget for surprises.
- Hiring Solely on Price: The lowest bid often reflects a lack of insurance, subpar materials, or hidden fees. Value quality and reputation over the bottom line.
- Changing Your Mind Mid-Project: “Scope creep” is a timeline killer. Finalize your fixtures and floor plans before the first hammer swings to avoid expensive change orders.
- Over-Improving for the Area: If you plan to sell, ensure your upgrades match the neighborhood’s price point. Don’t put a mansion-grade kitchen in a starter home.
- Neglecting Lighting and Outlets: Homeowners often forget functional needs. Plan your electrical layout early so you aren’t stuck with extension cords in your new space.
- DIY-ing the Technical Stuff: While painting is a great DIY task, leave structural work, plumbing, and electrical to licensed pros to ensure your home stays up to code.
Can I live in my home during a renovation in Toronto?
For targeted renovations, a bathroom, kitchen, or basement, yes, most homeowners remain in their home. We maintain clean, liveable conditions in unaffected areas. For full home renovations, some Toronto homeowners temporarily relocate. Grand Design Build gives you an honest assessment of disruption levels during planning, before you sign anything.
Do I need a permit for my home renovation in Toronto?
It depends on scope. Cosmetic renovations (painting, flooring, cabinet swaps) typically don’t require a permit. Structural changes, wall removals, electrical upgrades, plumbing moves, and envelope changes require a City of Toronto building permit. Grand Design Build assesses permit requirements for every project and manages all applications, submissions, and inspections entirely on your behalf.
Pro Tip: Always check with your local building department first. Unpermitted work can complicate future home sales and may lead to fines.
Does Grand Design Build handle the permit for my renovation?
Yes. For any home renovation in Toronto requiring a building permit, Grand Design Build handles the full process: assessing whether a permit is required, preparing and submitting the application, producing structural drawings where required, coordinating City inspectors throughout construction, and obtaining final sign-off at completion.
