Which of the following is NOT a criterion needed to be deemed a "bedroom"?

A space is classified as a "bedroom" based on several established criteria, which help determine its suitability and intended use for sleeping purposes. One of the key criteria is that the space must provide privacy; this is essential because a bedroom is expected to be a private area for individuals to rest.

Another important aspect is that a bedroom should be a habitable or planned habitable space, which means it must meet certain physical requirements, such as having adequate size, ventilation, and natural light. Additionally, while it's not a strict requirement for functionality, having a full bathroom conveniently located is often preferred for convenience and comfort, but it is not essential for a space to be classified as a bedroom.

The correct answer indicates that entry from the outdoors is not a criterion needed to deem a space a bedroom. A bedroom can indeed have entry from within the home, and it is often the case in many residential designs. Therefore, while a private, habitable space that may sometimes be associated with bathroom access is important, the way in which one enters the room—whether through outdoor access or internal pathways—does not disqualify it from being a bedroom.
