Windows, plumbing & mechanical
What's the purpose of adding Egress windows to your basement.
Main purposes:
Emergency escape: They provide a way for people inside—especially in basements or bedrooms—to get out quickly if doors or hallways are blocked.
Firefighter access: They allow emergency responders to enter the home from outside if needed.
Legal safety requirement: Building codes in places like Ontario require egress windows in certain rooms (like basement bedrooms) to make those spaces legally livable.
Where you usually see them:
Basement bedrooms
Finished basements
Any sleeping area without direct door access to the outside
Key features:
Large enough opening for a person to climb through
Easy to open without tools or keys
Often paired with a window well (for below-ground basements)
Why they matter:
Without an egress window, a basement bedroom can become a trap in a fire or emergency, which is why they’re strictly regulated.
