California Residential Inspector Practice Exam

The standard minimum width for egress windows in bedrooms is 20 inches. This requirement is part of safety guidelines to ensure that individuals can easily exit a room in the event of an emergency, such as a fire. The dimensions for egress windows are established by building codes, which specify that the window must have a minimum opening size to allow for a clear escape route.

Having a minimum width of 20 inches ensures that the window provides enough space for people, including those with mobility challenges, to escape safely. This also aids emergency responders who might need to enter the space quickly. The overall opening should not only meet the width requirement but also have a minimum height and area to be considered sufficient for egress.

In contrast, options that suggest widths less than 20 inches do not comply with local building codes designed to provide safe exit routes, especially in emergency situations. The specified width of 20 inches strikes a balance between safety and practical window design for residential structures.
