I don't know about you, but when I eat at restaurants or visit buildings I enjoy having a look at their toilet rooms. I look at the manufacturers of the fixtures and accessories, the type of finishes they used and if it is compliant with ADA. If you happen to walk in while I am looking around, then I'm the weirdo taking pictures. I find that they are usually compliant but I surprisingly still find ones that are not. Possibly because they did not get a permit or the construction cost of the remodel was not over $50,000, which is the maximum for not having to register a project with TDLR for a plan review and inspection. This article will study each element of a toilet room and the requirements for what it takes to create one that is compliant.
A toilet room usually consists of obviously a toilet, lavatory and all of the accessories, such as grab bars and dispensers. There are many layouts of this type but we will explore one very simple design and the code requirements for each aspect. Not all code requirements or exceptions are discussed here, so make sure you read and understand the sections in the 2012 Texas Accessible Standards (TAS). You can download the TAS in PDF form.

The required clearance around the water closet is allowed to overlap clearances required at other fixtures and the turning space. Refer to Figure D. (603.2.2 Overlap)
You are not allowed to overlap the accessories for other fixtures such as soap dispenser, paper towel dispenser or trash, since these are not associated uses of the water closet but by the lavatory. (Technical Memorandum 2013-17 Water Closet Clearance Overlap)
The door swing is allowed to overlap the clearance for a water closet and a lavatory in a toilet room as long as there is a 30" (760 mm) x 48" (1220 mm) clear floor space beyond the arc of the door. Refer to Figure E. (603.2.3 Door Swing Exception 2)
