08 Aug Demystifying Canadian Residential Code Requirements For Basement Windows And Learn How Our Window Wells Exceed Them!

Basement windows are more than just a nice way to let in light. They’re a key part of your home’s safety. This is especially true if your home has basement bedrooms. But we know interpreting the rules around egress windows can feel overwhelming. We’re a trusted source for understanding the code, routinely helping contractors and homeowners stay code-compliant—and then some.

What Does The Code Require?

Simply, it depends on where you live. In Canada, building codes are regulated by each province/territory and are largely similar nationally. We’ll use Ontario for our examples, but you can refer to this list to find the codes for your area. Municipalities often have online resources outlining requirements for their residents, and these are a good starting point.

Summarized, Ontario’s building code specifies that any basement bedroom must have at least one egress window. That means having a bedroom window large enough for an adult to escape through during an emergency, like a fire.

– The bedroom window must open without tools or special knowledge and meet specific size minimums (typically 0.35 m² or about 3.8 sq. ft. of clear opening space).

– Beyond size, the window well outside must allow the window to fully open easily from the inside.

– The window needs at least 550 mm (about 22 in.) of clearance in front so an adult can safely exit without obstructions.
