This requirement ensures that the width of a doorway to the washroom and the bedrooms in relation to the corridor width leading to those rooms in a dwelling unit or a hotel/motel suite can provide for basic maneuverability into and out of the room. The Code does not require these washrooms (except the 15% required by Sentence 3.8.2.1.(5) and 10% required by Article 3.8.2.4.) to be barrier-free.
