According to the 2010 ADA Standards, what is the required height for accessible wall-mounted controls for a side reach?

  1. 15" to 44" AFF

  2. 9" to 48" AFF

  3. 15" to 48" AFF

  4. 9" to 44" AFF

The correct answer is: 9" to 48" AFF

The height for accessible wall-mounted controls for a side reach, as specified by the 2010 ADA Standards, is 9 inches to 48 inches above the finished floor (AFF). This range is established to ensure that individuals using wheelchairs or those who have limited reach can easily access controls without difficulty. The lower limit of 9 inches accommodates individuals who are seated, while the upper limit of 48 inches ensures that controls are within easy reach for a wide range of users. This understanding is critical for designers to create inclusive environments that comply with ADA requirements, ensuring accessibility for all individuals. The allowable reach range emphasizes the importance of considering various user needs in interior design, reinforcing the principle of universal design.
