According to the IRC, what is the maximum height for the installation of switches?

The maximum height for the installation of switches, as specified in the IRC (International Residential Code), is 6 feet 7 inches. This requirement is in place to ensure accessibility for all users, including those with disabilities. The height limit allows for ease of operation by individuals who may have difficulty reaching higher switches due to various reasons, including mobility impairments.

In residential settings, adhering to this height guideline helps comply with the accessibility standards that are part of the IRC framework. These standards aim to create safer and more usable environments in homes, ensuring that essential functions like lighting control are available to everyone.

Other taller options exceed this accessibility guideline, which is why they would not be appropriate choices for switch installation height.
