Markham's Best Neighbourhoods for Buyers Who Want a Home With a Finished Basement
Markham's Best Neighbourhoods for Buyers Who Want a Home With a Finished Basement
A good finished basement can add a family room, a gym, a guest suite, or an office. A poor one can hide problems. Here is how to tell the difference.
Neeraj Moolchandani is a top real estate agent in Markham, Ontario.
The Short Answer
A good finished basement in Markham has comfortable ceiling height, real windows, dry walls and floors, and permits for the work. As a reference, the Ontario Building Code requires at least 1.95 metres of ceiling height, or 1.85 metres under beams and ducts, for a basement secondary suite, and bedroom windows that open to at least 0.35 square metres. Established areas like Markville, Unionville, Middlefield, and Markham Village have many owner finished basements. Newer areas like Cornell and Wismer often have builder finished or unfinished ones. Lookout and walkout lots offer the most light.
Neeraj and the Kaizen Real Estate Team, one of the teams Markham families trust for honest home advice, walk through many basements with buyers. This guide is about using a basement as family living space. If you want a rental unit, see our legal basement apartment guide.
What Makes a Great Basement
- Ceiling height. Taller ceilings feel like real living space. Measure under beams and ducts too.
- Windows. Larger windows bring light and a safe way out. Bedrooms need an opening window.
- Dry. No musty smell, stains, peeling paint, or white mineral marks on walls.
- Layout. Open rec room, a full bathroom, storage, and a laundry area that does not split the space.
- Flooring. Vinyl plank, tile, or engineered floors handle moisture better than carpet.
- Permits. Ask for permits and final inspections for the finishing work.
Lookout and Walkout Basements
| Type | What It Means | Why Buyers Like It |
|---|---|---|
| Standard | Below grade with small windows | Most common; good for rec rooms and storage |
| Lookout | Larger windows above grade on a sloped lot | Much more natural light |
| Walkout | Door directly to the backyard | Bright, easy access, and flexible for guests or a suite |
| Walk up | Separate stairs up to the yard | A second entrance for family or a future unit |

Where to Look
- Markville, Unionville, Middlefield and Markham Village: older homes, many with owner finished basements. Check the quality and permits carefully.
- Berczy and Angus Glen: larger homes, often with higher end finished basements.
- Cornell, Wismer, Greensborough: newer homes, sometimes builder finished or left unfinished, which lets you finish to your taste.
Lots near ravines or on slopes are more likely to have lookout or walkout basements. See our ravine lot guide.
Moisture: Check Carefully
- Look and smell for dampness, especially in corners and closets.
- Ask about past water issues and insurance claims.
- Check for a sump pump and backwater valve. Markham's rebate program may help with costs.
- Look at grading and downspouts outside.
- Ask your inspector to use a moisture meter. See our inspection checklist.

How It Affects Value
Buyers usually value a basement less per square foot than the main floors, but a well finished, dry, bright basement can make a home stand out and sell faster. A poorly done one, or one finished without permits, can raise concerns with buyers, lenders, and insurers. In September 2026, the median Markham detached home sold for $1,381,500, according to TRREB, and the quality of the lower level is often what separates similar homes.
The right basement adds a whole floor of living. Reach out anytime. Call or text Neeraj at (647) 370 8885.
