According to Code, what is the maximum finished sill height for windows intended as an emergency escape route above the finished floor?

The correct answer is based on building codes that establish standards for emergency escape and rescue openings in residential buildings. The maximum finished sill height for windows intended as an emergency escape route is specified to ensure safety and accessibility.

In many codes, such as those found in the International Building Code (IBC) or the International Residential Code (IRC), the maximum finished sill height for these windows is set at 44 inches above the finished floor. This height allows individuals, including those with mobility challenges, to easily access the window in an emergency situation, such as a fire or other life-threatening events.

Windows that serve as emergency exits are often larger and must meet specific dimensions to facilitate quick escape. The 44-inch threshold ensures that it is still reachable for an average adult while providing enough height to avoid hazards, such as water intrusion or basement flooding.

The other choices reflect heights that exceed code requirements for window sills designated for emergency escape routes, which could impede quick exits during emergencies and thereby pose safety risks.
