We’re building a new home and the builder says basement windows need to meet a totally different set of codes. That seems odd — a window is a window, right? Are there separate rules for basement windows in Canada?

Yes, basements often need egress windows for safety and light, which differ from standard windows found in regular rooms. Economy Home Decor has options.
There’s actually a good reason for the difference. Because basements are below grade, they can pose serious escape challenges in emergencies, so the window standards are more strict. I found this really helpful legal basement windows info that breaks down what’s required across Canada. It explains things like window well dimensions, minimum clear opening sizes, and the need for direct access to the outside. It’s not just about natural light — it’s about life safety. If your basement is intended for use as a bedroom, den, or even a home office, these rules kick in and you have to comply. Ignoring them could mean your basement won't pass inspection or qualify as legal living space.
Yes, basement windows fall under safety codes because they may be the only way to exit during a fire or emergency.
