Final answer:
The minimum net clear opening requirement for an egress window is 5.7 square feet to provide a safe emergency exit, but local building codes may vary.
Step-by-step explanation:
The minimum net clear opening requirement for an egress window is 5.7 square feet. This is a safety requirement to ensure that in the event of an emergency, such as a fire, occupants can use the window as an exit point. However, the minimum size can be subject to change depending on local building codes and regulations, which are designed to maintain a high standard of safety in residential and commercial buildings. It's essential to consult with local authorities or a building code expert when planning construction to ensure compliance with all safety requirements.
According to the IRC, an egress window must have a minimum net clear opening of 5.7 square feet. This means that the openable area of the window, when fully opened, must be at least 5.7 square feet.
It's important to note that the requirements may also specify a minimum height and width for the window, as well as other safety features such as a clear exit path and proper hardware.
