Well I think I've gone over 3.7.2.2 (NBCC 2015) more times than I care to admit so finally I think I need someone to spell it out for me. In applying 3.7.2.2. for example to a Group D office (Business & Personal Services) with an occupant load of 35 people it appears simple to me that 2 washrooms are required per table 3.7.2.2. B; that is until I read (and re-read & reach for a glass of whiskey) 3.7.2.2 (3), the wording appears to say that if I provide only one UWR then I cannot use that in my calculations, so must I plan for 1 UWR plus 2 other WRs? But if I provide 2 UWRs the that will suffice? To be blunt if the both WRs are UWRs then that meets the code but if only 1 is then 2 WRs need to be provided in addition to the one which is a UWR?
I have been pulled up on this previously where I had provided 1 UWR and 1 WR, the AHJ demanded we install 2 UWRs as the building was a Business & Personal Service with an occupant load of 15 and their stance was that 3.7.2.2. (4) did not apply to 3.7.2.2. (12). It was a small unit and not in a strip mall.
Some clarity would be appreciated.
