Volume VI Number 9 September 2011 |
The 2010 ADA Standards are almost identical to the 2003 ANSI A117.1, but not quite. The main difference is that ANSI is part of the model code and will continue to change as the building code changes. The ADA is a civil rights law which gives us guidelines on how not to discriminate against the disabled community. Below are some examples of how the Title III of the ADA is different from the ANSI building accessibility standards. |
| Doors in Series |
Section 404 in both the ADAAG and the ANSI discusses doors and manuevering clearances. But ANSI is more stringent when it comes to doors in series. These type of doors are the one's that are more typically found in vestibules and are such that you open one and have to go through the next one to enter the space.
The ADAAG has figure 404.2.6. which shows you a requirment to have the manuevering clearance at the door plus 48" distance between door swings or between walls, depending on the door swing.
ANSI has a different requirement, where the vestibule itself must have a 60" turning diameter within.

| Grab bars |
|
The ADAAG has a requirement for the side grab bar at restrooms, shown in figure 604.5.1 which states that the side grab bar should be horizontal and 42" long min and an overall distance from the back wall of 54".
ANSI requires the same from the side grab bar, but it also requires a vertical grab bar that is 18" min and mounted between 39"-41" away from the back wall and 39"-41" a.f.f.
