ADAAG, TAS, Title 24, ANSI, FHA,UFAS....So many codes, so little time!
What happens if your project falls in a jurisdiction that requires not only the ADA requirements but their own accessibility standard?
What happens if they differ?
How should you design?
Regulatory agencies recommend that you should select the most stringent.
Here are some examples of the differences between the codes, but remember to always check what jurisdiction you are working under to see what code
needs to be utilized:
|Water Closet Layout|
The ADAAG has figure 28 which shows you the three layouts you can use for a water closet not located in a stall.
Depending on the direction of travel this Figure guides you in the amount of clear floor space required at the water closet and the location of an adjacent lavatory.
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.
ADAAG, TAS and ANSI requires that a 36" long min. grab bar be used in the rear of the water closet.
ANSI and Fair Housing Act will allow a 24" long grab bar in certain situations. ANSI has an exception where a 24" grab bar is allowed if there is not enough room for a 36" long bar. And Fair Housing will allow it in the accessible units to have a 24" rear grab bar .
But unless you are strictly dealing with ANSI, in a non-residential restroom, the rear grab bar must be 36" min.
