I have a multi occupancy tenant improvement where we are trying to calculate the minimum plumbing fixtures that are required. I have proposed using the ratio method where each occupancy is calculated separately. This generates a fractional number for the fixtures. Once each occupancy is calculated and generates its own fractional number all of the occupancies are totaled and then rounded up to the next higher number to establish the combined minimum fixture count.
This is the method that Ron, RLGA has described in his code corner article #33, fall 2010. This was for IBC
I am having a difficult time with a jurisdiction saying that this ratio method is per Chapter 29 of the CBuildingC which has not been adopted by California as well as this jurisdiction. It seems to me like the language regarding minimum plumbing fixtures in the 2016 CPlumbingC has the same language where the multiple occupancies are summed and then rounded up.
Am I missing something? There must be a way to use a ratio rather than just adding up more and more fixtures for each separate occupancy.
