Ask your code official....
But if it was my family that was going to die in the fire...yes..I would put an egress in the bedroom. How much is someone worth to ya..
The egress is not so someone can get out..it is so the fireman can get in and save your smoke filled lungs. If they don't see an egress window in the basement, they won't always look down there first. And no hatchways are allowed because if something falls on them ,or snow and ice gets built up...you cannot get out.
Try not to save $$ on this one...you won't like yourself if something were to happen. You installed smoke detectors in your house right?
Welcome aboard, hope I didn't scare ya too much, just want folks to be safe.
