ADA Braille Sign Installation Requirements
Ensure a clear floor space measuring 18 inches by 18 inches remains unobstructed by any protrusions up to a height of 80 inches.
The ADA Braille Sign Installation Requirements as defined by the US Access Board ADA Signage Guide:
"A clear floor space 18 inches minimum by 18 inches minimum must be centered on the tactile characters. This placement of the clear floor space provides unobstructed standing space at the sign for reading by touch. This space must be free of any protrusions to a height of 80 inches. For safety, the space must be located beyond the arc of any door swing to a 45° open position. This effectively sets a minimum, but not an absolute, distance of tactile signs from out-swinging doors. While the clear floor space must be centered on the tactile characters, signs can be located varying distances beyond the door swing."
