What is the Code for Egress Windows?

If you are a homeowner in the Hamilton or Burlington area – and your home has a full basement – then you should strongly consider egress windows for your basement. Egress windows are simply windows that can be easily opened from the inside without keys or tools. 

They are beneficial for several reasons. First, they allow light into your basement, which makes it nicer for you and your family to spend time in the basement – but even more importantly, they can be used as an emergency exit if necessary.

Ontario Building Code Means of Egress

Because of their importance, it is no surprise that egress windows are heavily regulated by the Ontario Building Code. For example, every bedroom in your home must have an egress window – so if you are planning to add a bedroom or apartment to your basement, it will be necessary to ensure that you have egress windows installed.

According to the building code, egress windows must meet the following criteria:

  • They must be easy to open from the inside without the use of tools.
  • They must open to a minimum area of 0.35 m2.
  • Each dimension of the opening must be at least 380 mm.
  • Must be able to stay open without the need for added support.
  • The sill height cannot be more than one metre (the exception to this rule is egress windows in basements).

For egress windows that have window wells (i.e., egress windows in basements), there are further requirements including:

  • There must be a space of at least 550 mm between the egress window and the window well.
  • If the window includes a sash that swings outward toward the window well, it must not reduce clearance in such a way that it would hinder a safe exit.
  • If you use a window well cover, it must be easily openable from the inside without the use of tools or special knowledge.
