With limited space and more affordability issues within Metro Vancouver and Burnaby BC real estate everybody from architects & developers to builders & homeowners are beginning to get just as creative as Shakespeare himself, with the use of space. One area in question is bedrooms and whether they must have a window or built-in closet. Here's what the BC Building Code says:
BC Building Code (2012)
184.108.40.206 Egress Windows or Doors for Bedrooms
Except where the suite is sprinklered, each bedroom shall have at least one outside window or exterior door openable from the inside without the use of keys, tools or special knowledge and without the removal of sashes or hardware.
220.127.116.11. Areas of Bedrooms
Except as provided in Articles 18.104.22.168. and 22.214.171.124., bedrooms in dwelling units shall have an area not less than 7 m² where built-in cabinets are not provided and not less than 6 m² where built-in cabinets are provided.
A window is not required if the space has a sprinkler. There is a size requirement of 75 sqft, or 65 sqft if there is a closet or similar built in.
So there ya go, a window and/or closet is not always required however, must meet other requirements and most notably, a fire sprinkler.
