California Legislature Resolution

"Resolved by the Assembly of the State of California, the Senate thereof concurring, that all designers and manufacturers of Braille tactile signage that contract with the State of California shall comply with the California Building Code when designing, developing, manufacturing, or implementing Braille tactile signage; and be it further resolved, that all agencies of the State of California shall comply with the California Building Code when designing, developing, manufacturing, or implementing Braille tactile signage; and be it further resolved, that the Chief Clerk of the Assembly transmit this resolution to the Director of the Department of Housing and Community Development."

Note: California Braille is significantly different from ADA Braille. California "Contracted Grade 2 Braille" shall be used whenever Braille symbols are specifically required. (See C.B.C. Section 1117B.5.6)

  • Braille fonts must be checked to be sure that they comply with Title 24 spacing.

    Title 24 requires the following Braille specifications: 1/10th inch is required between each dot within a cell, measured form the dot centers. 2/10th inch is required between each cell within a word. Measure from the center of the dots in the second column of the first cell to the center of the dots in the first column of the next cell. Dots must be a minimum of 1/40th inch high at the apex, as in the following figures:

    Sign companies must be sure to have a special font with this spacing, since many nationally supplied fonts are NOT in compliance, and have spacing which is too close.
  • Grade 2 Braille is a "shorthand" form of Braille, which instead of having one Braille cell to correspond with each letter uses one or more cells to correspond with groups of letters or even whole words.
