California IDEX Practice Exam

How wide should an interior accessible route be if it is 150' long and serving an occupant load of 10 or more?

1. 36"

2. 40"

3. 44"

4. 48"

The correct answer is: 44"

An interior accessible route that is 150' long and serves an occupant load of 10 or more should have a width of 44". This is based on the California Building Code requirements for accessible routes, which state that when serving an area with an occupant load of 10 or more, the accessible route width should be a minimum of 44" to ensure safe and easy passage for individuals, including those with disabilities. Option C, 44", is the correct answer as it aligns with these accessibility requirements.
