Ask Mike Holmes
Mike and his expert industry guests answer some of the most commonly asked questions.
1. What is the difference between a legal and illegal basement suite?
A legal basement suite meets all local building codes, fire safety rules, and zoning regulations. It has proper permits, egress windows, separate ventilation, and a safe exit route. An illegal suite? No permits, missing safety features, and a major risk—not just for tenants, but for homeowners too.
2. What are the key requirements for a legal basement suite in Canada?
The exact rules vary by city, but generally, a legal basement suite needs:
- Proper permits
- A separate entrance
- Egress windows for emergency exits
- Proper ceiling height (usually 6’5” to 7’)
- Fire-rated walls and doors
- Independent heating and ventilation
- Compliance with electrical and plumbing codes
Skipping any of these could lead to big fines being paid or even put lives at risk and you don’t want that liability.
3. How much does it cost to build a legal basement suite in Canada?
Costs vary by location and size, but expect to spend $100,000–$150,000 for a fully legal suite. It also depends on permits, upgrades (like soundproofing), and whether your basement already meets key building codes.
4. Do you need a permit to build a basement suite in Canada?
Yes! A permit is mandatory to ensure the suite meets safety and zoning laws. Without it, you could face fines, insurance issues, and even eviction of tenants.
5. What are egress window requirements for a basement suite?
An egress window is a must-have for fire safety. In most Canadian cities, it must be at least 15 inches in any direction, with an opening big enough for someone to escape. If your basement windows are too small, you’ll need to enlarge or replace them to make the suite legal.
6. What are the best flooring options for basement suites?
Basements need moisture-resistant, durable flooring. The best options? Luxury vinyl plank (LVP), tile, or engineered hardwood. Avoid carpet—it traps moisture and can lead to mould.
7. How can I make a small basement suite feel bigger?
Maximize space with light-colored walls, open layouts, and multi-functional furniture. Use pot lights to brighten up the space and pocket doors to save room. Good design makes a basement feel more like an apartment and can help attract quality tenants.
8. What should I check before buying a home with a basement suite?
Check if it’s legally registered—don’t just take the seller’s word for it. Look for permits, fire separations, proper ventilation, and separate utility meters. If it’s not designed as a legal suite, factor in the cost of bringing it up to code before buying. This can include adding a separate entrance, egress windows, need to change the layout of the space, having a separate electrical panel and heating/cooling ducts.
9. What are the biggest challenges of building a basement suite in Calgary?
Calgary has strict zoning laws and fire safety codes. If your home is in an area not zoned for secondary suites, you may need to apply for a rezoning permit. Also, some basements don’t meet height requirements—so check before starting renovations.
