Converting a Basement into a Rental Apartment: What You Need to Know
Turning a basement into a rental unit can be an excellent way to generate income and increase a property’s value — but it requires strict compliance with building codes, municipal bylaws, and safety standards.
1. Regulatory Compliance
Each Canadian province has its own building and fire codes, along with additional municipal regulations. The main requirements typically include:
-
Minimum floor area and ceiling height
-
Size and number of windows
-
Plumbing, heating, and ventilation systems
-
A complete kitchen and bathroom
-
Fire-resistant insulation, smoke and CO detectors
-
Electrical safety and accessible exits
The apartment must have at least two exits, one of which can be a window that is easily accessible in case of emergency.
2. Risks of a Non-Compliant Unit
An unregistered or non-compliant apartment can lead to hefty fines and may endanger the safety of tenants. Renters have the legal right to request proof of compliance from the property owner.
3. Conversion Costs
The total cost depends on the current condition of the basement.
A finished basement that already has plumbing and large windows will cost less to convert than an unfinished space.
Expenses usually include installing a bathroom, kitchen, private entrance, and bringing everything up to code.
4. Added Value
Converting a basement into a rental suite can yield an average return on investment of about 75 % upon resale.
For instance, a $50,000 renovation could add roughly $37,500 to the home’s market value.
5. Steps to Follow
Before starting the project:
-
Request multiple quotes and hire a qualified contractor
-
Review municipal bylaws and obtain all necessary permits
-
Plan your financing, for example through a mortgage broker such as Multi-Prêts Équipe Caron
