Based on Ch 12 of IBC 2015, habitable spaces must be served by natural or mechanical ventilation as well as natural or artificial light. Technically, this would allow you to provide an interior bedroom that does not have a glazed opening in an exterior wall as long as the artificial light minimums are met and the bedroom is mechanically ventilated. Aesthetics of not having a window in a bedroom aside, are there any other restrictions in the IBC the would not allow an interior bedroom without an operable opening to the exterior?
