Switch height: 44 in AFF (universal-design optimum), 48 in (code max), 36 in (kids)
ROT/EXT-SWITCH-HEIGHTDescription
Light switches at 44 in AFF (height of the lower hand of an average standing adult AND within the seated-user reach range from FHA Ch 5). Code allows up to 48 in (the FHA seated reach max). For child-friendly play areas / kid bathrooms, drop to 36 in. Consistent height throughout the home reads as deliberate; inconsistent heights read as careless.
Why this exists
44 in is the standard universal-design height — works seated, standing, and within reach of a 7-year-old. Architects should specify switch height on the electrical plan as a project-wide standard.
