Hi,

I'm wondering if I need to add an egress window in a basement guest room. My basement is a walkout and the walkout door will be 15 feet from the proposed bedroom door. I live in Ottawa, ON.

Thanks

All bedrooms in basements must have means of egress to be legal. Assuming your guests are not renters or government officials, you should be fine without, no one will report you for not having one. But you could be regretting it for many years if a fire ever broke out and they were trapped in the home. Legally speaking, yes it is in Ontario. Although your exterior door on that floor serves as egress.

Yes you must have an egress window unless there is a door leading directly to the outside from that room. It is a Canada wide law. Here is the law as it relates to Ottawa.

Specifically regarding Ontario building code.

Quick answer is yes. Any room that doesn't have a door connecting directly to the outside needs a window at least 3.5ft sq. And nothing under 15". I.e 21"x 21" is about as small as you'd want to go.

Hi Shanna.

According to section 9.9.10.1. Egress Windows or Doors for Bedrooms of Ontario Building Code, you are not required to have an egress window for a bedroom if you have a door leading directly to the outside on the same level as the bedroom. The exact clause is "Except where a door on the same floor level as the bedroom provides direct access to the exterior, every floor level containing a bedroom in a suite should be provided with at least one outside window that... (meets certain size and placement)". In your case the walkout door from the basement will serve as an exit door for that level, so you are not required to have an egress window in the bedroom.

However, you are required to provide a window in a bedroom for daylight requirements of the code (OBC 9.7.2.3 Minimum Window Area). The glazed area should be at least 5% of the room area.

You should also make sure that you have your building permit in place if you are enlarging or inserting windows.

Hi Shanna,

Yes Victoria is correct as that is what the building code says. But you should verify what your local municipal bylaws may have in this regard.
