Florida Building Code Practice Exam

What does a vertical rise of 24" in a ramp require as a minimum horizontal length for compliance?

1. 10'

2. 12'

3. 18'

4. 24'

The correct answer is: 24'

In the context of the Florida Building Code, ramps must be designed to comply with specific slope requirements to ensure accessibility and safety. For a ramp with a vertical rise of 24 inches, it is essential to understand the maximum allowable slope for accessible ramps. The code generally mandates that the maximum slope for a wheelchair ramp is 1:12, which means that for every inch of vertical rise, there needs to be at least 12 inches of horizontal run. Therefore, for a vertical rise of 24 inches, the minimum horizontal length required to comply with this guideline would be 24 feet (24 inches x 12 inches). This means that the correct answer is based on this slope ratio. A vertical rise of 24 inches necessitates a horizontal distance or length that allows for this gradual incline, ensuring it is accessible for individuals using mobility devices. If the horizontal distance was shorter, the ramp would be too steep, creating potential safety hazards for users. In the context of the choices provided, the need for a consciously manageable and compliant ramp design mandates adhering to this established standard.
