Renovations that add the most value in Ontario
Not all renovations pay you back. Here are the projects that add the most value to an Ontario home, and the ones where it is easy to over-spend.
Quick answer
In Ontario, the renovations that add the most value are kitchens, bathrooms, finished basements and second units, and exterior or curb-appeal upgrades. Kitchens and bathrooms commonly recover 50 to 80 percent of their cost, while a legal second unit can add rental income on top of resale value.

Which renovations return the most in Ontario?
Return on a renovation depends on the home, the neighbourhood, and the quality of the work, but some projects consistently outperform. Here is how the most common upgrades compare.
| Project | Typical cost recovered | Why it works |
|---|---|---|
| Kitchen renovation | 50 to 80% | Buyers judge homes by the kitchen |
| Bathroom renovation | 50 to 70% | Updated baths remove buyer objections |
| Finished basement | 50 to 75% | Adds living area at low cost per sq ft |
| Legal second unit | High + rental income | Ongoing income plus resale value |
| Curb appeal and exterior | High | Cheap changes, strong first impression |
| Energy upgrades | Moderate + savings | Comfort and lower bills |
Percentages are general guidance, not a promise. The best return comes from quality work that fits the home and the local market, not from over-building for the street.
Kitchens and bathrooms lead the way
Kitchens and bathrooms are where buyers form their strongest impressions, which is why they return the most. A dated kitchen or bathroom is often the single reason a buyer moves on, and a clean, well-built update removes that objection. You do not always need a full custom kitchen either. A smart mid-range renovation with quality cabinets and quartz counters often delivers the best value.
See real numbers in our kitchen cost guide and bathroom cost guide.
Add income with a second unit
If you want a renovation that pays you back every month, a legal second unit is hard to beat. A basement apartment, laneway suite, or garden suite adds rental income and resale value at the same time. Ontario rules now make it easier to add units on many lots. We cover both paths in our basement finishing guide and our laneway and garden suite guide.

Talk to ZeybekDo not overlook curb appeal and the exterior
First impressions are cheap to improve and easy to underestimate. New or refinished doors, a clean front entry, updated garage doors, fresh exterior paint, and a tidy deck or landscape all lift the value a buyer places on a home before they walk inside. These are lower-cost projects with a strong impact. Browse examples in our outdoor and decks portfolio.
What renovations can you over-invest in?
Value has limits. It is easy to over-improve for the neighbourhood, and some projects rarely pay for themselves at resale. Be careful with:
- Ultra-high-end finishes in a mid-market home
- Highly personal choices that narrow the buyer pool
- Pools and elaborate landscaping, which many buyers do not value
- Converting bedrooms into single-purpose rooms
The goal is to match the quality of your renovation to your home and your goals. That balance is easier with a contractor who will tell you the truth, which is why it helps to read how to choose a contractor.
Frequently asked questions
What renovation adds the most value to a home in Ontario?
Kitchens and bathrooms typically add the most value in Ontario, commonly recovering 50 to 80 percent of their cost, followed by finished basements, legal second units, and curb-appeal upgrades.
Do finished basements add value?
Yes. A finished basement adds usable living area at a lower cost per square foot than an addition, and a legal second unit in the basement can add rental income on top of resale value.
Is a kitchen or bathroom renovation a better investment?
Both are strong. Kitchens usually return the most in absolute dollars because buyers weigh them heavily, while bathrooms are lower cost and remove objections. Doing both well makes a home much easier to sell.
Can you over-renovate a home?
Yes. Ultra-high-end finishes in a mid-market home, very personal choices, and features like pools often do not return their cost. The best value comes from quality work that matches the home and neighbourhood.
Do energy-efficiency upgrades add value in Ontario?
They add comfort and lower energy bills, and increasingly matter to buyers. The financial return is moderate, but combined with rebates and daily savings they are often worthwhile.
