ADA vs. ANSI Water ClosetsPosted on - Tuesday, February 2nd, 2010
The ADAAG has figure 28 which shows you the three layouts you can use for a water closet not located in a stall
ANSI, on the other hand, only has one way that they allow it. Figure 604.3. This figure describes not only the clear floor space required, but also that a fixture may not overlap the space.
When designing in a municipality that requires the use of IBC and ANSI, make sure you don’t design per ADAAG, or you would miss this one.
