The Berwyn inspectors want me to put egress windows on one of the windows in all bedrooms and one in the basement because it is habitable even though nobody will live there. The bedrooms have the regular double hung windows. I am loathe to change them, I've never heard of requiring special egress windows when you have the regular double hung windows. I can see if you could not get out of them but that is not the case. The basement I can see. Does anyone have any advice on this? I have gotten a few names from the city of Berwyn such as Air Guard on Cermak road. Pls advise.
