What is an Egress Window?
An egress window is a window that meets building code requirements for emergency escape and rescue, typically required in basement bedrooms or below-grade living spaces.
Why Egress Windows Matter in Real Estate
In Canadian residential construction, egress windows ensure occupant safety by providing a secondary exit in the event of a fire or emergency.
To be code-compliant, an egress window must:
- Have a minimum unobstructed opening (e.g., 0.35 m²)
- Be easily openable from the inside without tools
- Have a sill height within allowable limits
- Provide direct access to the exterior or a legal window well
Egress windows are especially important in finished basements used as bedrooms or rental suites, and may be required to pass inspection or qualify for permits.
Understanding egress window standards is essential for renovators, landlords, and homeowners converting basement spaces.
Example of an Egress Window in Action
To meet code and legally list the basement bedroom, the homeowner installs an egress window with proper clearance and window well.
