What is the maximum gradient allowed for accessibility ramps?

The maximum gradient allowed for accessibility ramps is 1:12. This means that for every 12 units of horizontal distance, the ramp should not rise more than 1 unit vertically. This standard ensures that ramps are manageable for individuals with mobility challenges, providing a smoother and safer transition between different levels. A gradient steeper than this could pose difficulties for wheelchair users or those who may have difficulty navigating inclines, leading to safety concerns and potential accessibility violations under laws such as the Americans with Disabilities Act (ADA).

While other gradients may be applicable in specific contexts, they do not meet the same level of accessibility as the 1:12 ratio, which is widely recognized as the standard for public access ramps.
