An egress window is one of the most vital elements in ensuring your basement apartment is legal in Ontario. These windows are required by the Ontario Building Code (OBC) and are a crucial safety feature that helps make your basement habitable and compliant with regulations.
What is an Egress Window?
An egress window is a window that allows tenants to exit the basement quickly and safely in case of an emergency. The OBC requires that any bedroom in a basement apartment has an egress window to ensure safety during emergencies such as fires. The window must be large enough to allow an adult to escape, and it must open without the need for tools or keys.
Why Are Egress Windows Required?
The main purpose of an egress window is to provide a safe and quick exit route. In case of a fire, an egress window ensures that tenants can escape without needing to go through the main house. According to the OBC, these windows must meet specific size requirements. Each egress window must have a minimum opening area of 0.35 square meters (3.77 square feet).
In addition, the OBC states that the window must be at least 15 inches wide in all directions, with a maximum sill height of 39 inches above the floor. If your basement windows do not meet these requirements, you must either replace or enlarge them to comply with the OBC.
What Happens if You Don’t Have an Egress Window?
Failing to install an egress window can result in your basement not being legal for rental purposes. An illegal basement apartment can lead to fines, insurance problems, and potential legal issues if something goes wrong. Without an egress window, your tenants will not have an adequate emergency escape route, which is a serious safety risk.
How to Ensure Your Egress Window Complies with the OBC
To meet OBC standards, an egress window must provide a minimum opening area of 0.35 square meters and be easy to open from the inside. Most casement windows are ideal for this purpose as they offer a wide, unobstructed opening when fully open. You must also install a window well if the window is below ground level, ensuring it has enough clearance for easy exit.
When in doubt, consult with an architect or contractor who understands OBC requirements to ensure that your egress windows are properly installed and comply with the safety standards.
Conclusion: Egress Windows Are Essential for a Legal Basement
Egress windows are not only required by the Ontario Building Code, but they are also crucial for ensuring the safety of your tenants. Installing egress windows in your basement is a necessary step to creating a legal basement apartment. Don’t overlook this requirement — make sure your renovation meets all OBC guidelines, including egress windows, to stay compliant and safe.
