2010 California Standards for Accessible Design (excerpts relating to Safe Harbors only)

Note: Portions of this document or referenced document qualify for 2013 CBC Section 11B-202.4, Exception 2, and all or part of this information may only apply to California “Safe Harbored” elements addressed in that Exception.


1117B.5 Signs and identification.  California's standards for signage are more stringent than Section 4.30 of the ADA Standards for Accessible Design.

1117B.5.3 Proportions.  Characters on signs shall be selected from fonts that have a width-to-height ratio of between 3:5 (60 percent) and 1:1 (100 percent) measured by the width of the uppercase letter "O" and height of the uppercase letter "I", and a stroke width-to-height ratio of between 1:5 (20 percent) and 1:10 (10 percent) measured by the width and height of the uppercase letter "I".

ETA Editor's Note

The requirements of 2010 CBC 1117B.5.3 shown above are similar to 1991 ADAAG 4.30.2, and they predate the 2010 CBC Supplement dated August 1, 2012, which was issued to resolve significant differences and/or conflicts between 2010 CBC and 2010 ADAS.  The requirements of 2013 CBC 11B-703.2.6 are identical to 2010 ADAS 703.2.6, and are more stringent than the earlier regulations.

ETA Editor's Note

Select portions of the 2010 California Building Code (2010 CBC) are provided for reference only. If you would like to see the 2010 CBC in its entirety, it is available for purchase from the International Code Council (http://www.iccsafe.org).
