I have a new house being built that has 3 double hung (tempered) windows in the living area where the bottom edge is barely above finished floor level. So basically you can open the bottom sash and have a clear opening (not including the screen) where anything or any one could crawl out the window and plummet to the ground 10 ft. below. I can't find any specific code requirement saying there has to be a guard or some type of fall protection to prevent this from happening. My only thought is it is a walking surface > 30" from grade? Therefore, requiring a guard or some way of limiting the opening to not pass a 4" sphere? Any thoughts? Thanks in advance for any replies. :banghd Coder
