Adding a Basement Egress
If you're a homeowner converting your basement into living space, you should think about creating a way for inhabitants to escape (other than the stairs) in case of fire or other emergency. This alternative exit is called a "basement egress" and can take the form of a window or door. If you are just using your basement for storage or laundry, an egress is not necessary, but if you are using it for any living space – family room, play room, home theater, or exercise room – it is a good idea. If you have a bedroom in the basement, an egress is mandatory according to most building codes.
