    Please clarify if 30″ x 48″ clear space at accessible lavatory can extend all the way to the back wall (if the 9″ toe clearance minimum is observed) or maximum 19″ from front edge of lavatory?

    • Dwight Ashdown says:

      The 30″x48″ clear space at a lavatory can extend 19″ back – from the front edge of the lavatory. So, if the 48″ dimension extends 19″ back from the front edge – then it extends 29″ in front of the lavatory.

    Please clarify in ref to the 18″ req distance from CL of toilet fixture to the adjacent wall ..is it minimum ? i.e. can it exceed that ..example 19″…20″..thanks

    • Dwight Ashdown says:

      The previous code requirement was 18″ from side wall to centerline of toilet. The new / current code is 16″ – 18″ from side wall to centerline of toilet. The intention is that the toilet be appropriately placed so a disabled person can appropriately use the grab bars that are mounted adjacent to and behind the toilet. If the toilet is more than 18″ it’s difficult for a person to use the grab bars. We’ve adjusted the dimension on some projects by “furring or building out” the side wall to make it 18″.

        I’m in the process of starting a remodel to one of the student lounge areas. Part of the remodel is to bring the current public restrooms to comply with current ADA code. I would like to confirm on the minimum and maximum dimensions. Could you provide me with the current California code that states the 16” to 18” from side wall to center line of the toilet? My approved drawings are showing 18” from the wall to the CL of the water closet. If I am able to use the 16” from the wall to the CL of the WC, I will not have to relocate the plumbing, since the existing WC’s are at 16” center line.

        • Dwight Ashdown says:

          The current code reference of 16″ – 18″ is described in my book ADA4CA.
          Be advised, however, that the code is changing on Jan. 1 2014 – to be 17″ – 18″.

  3. LG says:

    Can the door swing overlap the clear space at the lavatory?

    • Dwight Ashdown says:

      Generally no. The ADA does provide an exception, which allows a door to swing into the clear floor space of an accessible fixture if a clear area 30″x48″ is provided outside the door swing.
      2010 ADA 603.2.3 Exception.

  4. Doug Waters says:

    Are the above drawings/Fig’s consistent with Both ADA and CBC current 2014 requirements for retail?

    • Dwight Ashdown says:

      The drawings are based on the 2010 CBC & 2010 ADA. Generally they are consistent with the 2013 CBC – with the exception that we need to update them to show the toilet centered 17″ – 18″ from the side wall and a clear space in front of the toilet 48″ x 60″. We’ll get right on it.

      Thanks,

      Dwight

      • Doug Waters says:

        About the 48″ x 60″ clear space in front of the toilet, can that be arranged either way (portrait and landscape)?

        Thanks!

  5. CCH says:

    The 18″ clearance from the centerline of the lavatory to the adjacent side wall seems to be a requirement specific to California. Is that in any national code? We normally set that distance at 15″ so the sink is in the center of the 30″ wide clear floor space.

    • Dwight Ashdown says:

      Interesting question. I was going to refer you to 2010 ADA 606 – but it appears that the only requirement there is that the lavatory be centered on a 30″ clear space – so on initial review, I would have to say that the 18″ offset is a California specific requirement.

  6. MWestfall says:

    In 2013 CBC can the clear floor space for the WC and lav overlap? I’m being told by a consultant that they can’t but I only find reference to the WC being 28″ to edge of lav, not clear floor space.
    Thanks

    • Dwight Ashdown says:

      Is this in a residential or commercial space? In our ebook – ADA4CA – available on iTunes, Amazon & Barnes & Nobel, you can find the answer with diagrams & code references to this and almost anything else you can think of.
