Final answer:
The minimum dimensions for a house egress door according to the International Residential Code (IRC) are 32 inches in width and 78 inches in height, to ensure safe and quick evacuation during an emergency.
Step-by-step explanation:
The egress door of a house, which is an essential component of building safety codes focused on ensuring a safe path for occupants to exit during emergencies, must be at least 32 inches wide and 78 inches tall, according to the International Residential Code (IRC). It is important to have a correctly sized egress door to facilitate quick and safe evacuation in case of emergencies like fires or natural disasters. Additional requirements may include the door being readily openable without the use of keys or special knowledge or effort, being equipped with proper hardware, and not being obstructed by barriers or alterations that prevent its intended use.
For example, the International Residential Code (IRC) states that a minimum clear width requirement for egress doors is 32 inches. This ensures that people can easily pass through in case of an emergency or during daily use.
The height requirement for egress doors varies depending on the specific building codes of the region. As a general guideline, a door height of 6 feet 8 inches (80 inches) is a common requirement.
