What is the minimum net clear height and width requirement for egress window openings?

The minimum net clear height and width requirements for egress window openings are essential for ensuring safety in case of emergencies. These dimensions are specified in building codes and are designed to allow for easy and safe exit from a building in an emergency situation, especially from basements and bedrooms that may not have other exits.

The correct option specifies a minimum height of 24 inches and a minimum width of 20 inches. This size requirement ensures that an average adult can fit through the opening without obstruction, providing a viable escape route. It is particularly important for egress windows because they serve as a secondary means of egress from a sleeping area and can be a life-saving feature in emergency circumstances.

Adhering to these dimensions helps ensure compliance with local building codes, which are established to protect occupants. Specifications such as these act as guidelines to facilitate safe evacuation, improve accessibility, and enhance the overall safety design of living environments.
