Chapter 6: Plumbing Elements and Facilities Toilet Rooms
Water Closets in Residential Dwelling Units
In residential dwelling units required to be mobility accessible, at least one bathroom must
comply (§809.4). Accessible water closets in dwelling units are permitted several exceptions
that allow some features, such as grab bars and knee and toe space below lavatories, to be
provided after construction as needed if certain conditions are met. In addition, lavatories can
overlap a portion of the water closet clearance if additional clearance depth is provided.
Exceptions for Water Closets in Dwelling Units
Note: All other applicable requirements, including clearances and turning space, must be met.
