A change in level surface over 1/2 inch requires what?

A change in level surface over 1/2 inch requires a ramp treatment to facilitate smooth transitions between different surfaces. Ramps are specifically designed to accommodate the needs of individuals with mobility challenges, allowing them to navigate changes in elevation safely and comfortably. Such treatments provide a gradual incline that is essential for accessibility, particularly in public spaces where compliance with the Americans with Disabilities Act (ADA) is mandatory.

Other options like a slope and a barrier could maintain differences in elevation, but they do not offer the usability needed for individuals intended to traverse the change in level. Steps, while functional, may not be appropriate for all users, especially those who use wheelchairs or have difficulty with climbing. Thus, ramp treatments directly address the need for accessibility at changes in level surfaces exceeding 1/2 inch.
