Are Egress Windows Required in Each Bedroom?

In Canada, ensuring the safety and legality of residential spaces involves adhering to various building codes, particularly when it comes to egress windows. These windows are not just architectural elements; they are lifelines during emergencies, offering safe exits for occupants and entry points for rescuers. Given the critical role they play, a common question arises: Are egress windows required in all bedrooms across Canada? The answer varies by province and territory. Here we will delve into the requirements specified by the National Building Code of Canada (NBCC) and provincial codes, providing a clear overview for homeowners and builders alike.

Understanding Egress Windows

Egress windows are specifically designed to provide a safe exit from bedrooms in the event of emergencies like fires. These windows must meet certain size and operational requirements to be considered compliant. The importance of these windows cannot be overstated, as they significantly increase the chances of safe evacuation and enable first responders to access the room if needed.

National and Provincial Requirements

National Building Code of Canada (NBCC) (Alberta, British Columbia, Manitoba, Prince Edward Island, Nova Scotia, Newfoundland and Labrador, New Brunswick,  Northwest Territories, Nunavut, Saskatchewan and Yukon): The National Building Code of Canada sets the benchmark for egress window safety standards for a number of provinces and territories. Under it, each bedroom must have an egress window. This requirement ensures that every sleeping area has at least one window that can be used for escape or rescue.

However, there are exceptions to this rule:

Ontario Building Code (OBC): In Ontario, the building code specifies that egress windows are required on each floor, rather than in each bedroom. This broader requirement aims to ensure that occupants have access to at least one exit on every level, offering flexibility in emergency situations.

Quebec Construction Code (QCC): Similar to Ontario, the Quebec Construction Code mandates egress windows on each floor. This approach allows for strategic placement of egress points, considering the layout and design of the home to optimize safety.

Importance for Homeowners

For homeowners across Canada, understanding and adhering to these varied requirements is crucial. Not only do egress windows provide a critical safety feature, but they also impact the legal and insurance aspects of home ownership. Ensuring that your home meets the local building code requirements for egress windows not only enhances safety but also avoids potential legal and financial repercussions.

All in All

In most Canadian provinces, the requirement for egress windows in every bedroom underscores the importance of having a safe, accessible exit in every sleeping area. In Ontario and Quebec, the focus shifts to ensuring access on each floor, reflecting a different approach to emergency exits. Regardless of the specific requirements in your province, the underlying goal remains the same: to provide safe, accessible exits in times of emergency. Homeowners and builders should always consult the latest version of their local building codes to ensure compliance and safety. Remember, when it comes to emergency preparedness, the right information and adherence to building codes can make all the difference.
