What is a Rental Suite?
A rental suite is a self-contained living unit within a home or property that is rented out to a tenant, commonly located in a basement or accessory building.
Why Rental Suites Matter in Real Estate
In Canadian real estate, rental suites offer homeowners a source of income and contribute to affordable housing, but must comply with zoning, safety, and permit regulations.
A legal rental suite typically includes:
- Private entrance
- Kitchen and bathroom
- Heating and ventilation
- Proper egress and ceiling height
Municipalities often distinguish between legal and illegal suites. Legal suites may affect mortgage qualification and insurance policies.
Understanding rental suites is important for investors, homeowners, and tenants evaluating income potential and legal compliance.
Example of a Rental Suite in Action
The homeowner installs a code-compliant rental suite in the basement, including a separate entrance, kitchen, and egress window for safety.

National average resale-price growth and housing-starts growth, smoothed over three months. The comparison illustrates the cycle; it does not establish how much a price change causes construction to change.
Trailing 12-month starts in centres of 50,000 or more remove the usual monthly seasonality. Ownership combines the homeowner and condominium categories; rental is shown separately.
