Ontario Building Code Practice Exam 2026 - Free Building Code Practice Questions and Study Guide

A barrier-free washroom typically refers to a washroom that is accessible for individuals with disabilities or mobility limitations. This includes features such as grab bars, a barrier-free entrance (i.e. wide enough for a wheelchair to enter), and a sink with knee clearance for easier use. However, a bathtub with a built-in seat is not required for a barrier-free washroom as it may not be accessible for all individuals and may not be necessary for personal hygiene. Therefore, option D is not a requirement for a barrier-free washroom in a residential building.
