What is the minimum clear knee space required below accessible countertops and surfaces?

The minimum clear knee space required below accessible countertops and surfaces is 27 inches. This dimension is established to ensure that individuals who use wheelchairs or have mobility impairments can comfortably approach and use the surface.

Clear knee space is important for accessibility because it allows for both the legroom and proper positioning needed when using the countertop or surface. The 27-inch height is designed to accommodate a range of users, supporting not just the physical presence but also the functionality of the space.

In terms of accessibility standards, such as the Americans with Disabilities Act (ADA), maintaining this clearance allows for effective use of work surfaces, ensuring both safety and comfort for users with varying needs. This helps create an inclusive environment that is accessible for all individuals, promoting independence and usability within designed spaces.
