Building Code (IBC), or the International Energy Conservation Code. Both the 2012 IBC and 2012 IRC require emergency escape and rescue openings for residential buildings of 4 floors or less, in sleeping rooms and basements with habitable space, for means of emergency egress. A fire escape can be a window, and if above the first floor with an approved ladder, or door that leads to a porch with ground access or a fire escape ladder. Federal rules, such as those of the U.S. Department of Housing and Urban Development (HUD), have requirements that follow ICC codes.
