What is the minimum window size in Group "R" occupancies below the 4th floor?

In Group "R" occupancies, which include residential buildings such as apartments and dormitories, there are specific requirements for windows to ensure adequate light and ventilation. The minimum window size stipulated by building codes for these occupancies, particularly for those located below the 4th floor, is 5.7 square feet. This size is critical not only for natural light and air circulation but also serves an important safety function, as it provides a means of egress in case of an emergency, such as a fire.

Windows of this dimension ensure that occupants can use them as an escape route if necessary, aligning with safety regulations that aim to protect residents' wellbeing. Requirements can differ for various occupancies and building types, which is why understanding the regulations specific to Group "R" is essential for maintaining compliance and ensuring safety in residential environments. The other options do not meet the established code requirements for this type of occupancy.
