Which of the following is NOT true about egress in a single family home?

  1. Dead bolts may be used on entry doors if it doesn't require a key.

  2. Only one exit is required from a second floor.

  3. Door knobs are permitted on all doors.

  4. Corridors must be 44"w.

The correct answer is: Corridors must be 44"w.

The option stating that corridors must be 44 inches wide is not true in the context of egress for a single-family home. In residential buildings, the width of corridors is generally determined by the requirements set by local building codes, which can vary by jurisdiction. While 44 inches is a common width for commercial buildings to allow for adequate egress in more crowded situations, single-family homes often have more flexible requirements based on the specific layout and usage of the space. The other statements are accurate regarding egress in a single-family home. The use of deadbolts on entry doors is permissible as long as they don't require a key from the inside, ensuring that occupants can exit easily in case of an emergency. For a second floor, often only one exit is required, typically through a stairway that leads to an exterior entrance. Finally, door knobs are permitted on all doors, as they do not typically impede egress, provided they meet specific operational regulations.
