What Determines a Bedroom
However, that has changed. A room no longer has to have a closet to be counted as a bedroom. This is mainly because a lot of the older Turn of Century homes did have closets of any kind and Armoires were used. Since Armoires are still available and can be used to store clothing, a closet is not essential to a bedroom.
Also, just because a room has a tiny window near the top of a ceiling like those found in older basements, it cannot be counted as a bedroom. Regional Building has guidelines for windows to have the proper ingress and egress for getting out of the window if an emergency situation happens.
There are other factors as well. For example, if you have to pass through a furnace room or utility or pass through one bedroom to get to another, those rooms cannot be counted as a bedroom.
For current and the most accurate guidelines, you can contact an appraiser or regional building.
