Water closet requirements for small B occupancy

[John Ogden]

I am trying to understand the implications of how Table 403.1 is organized. The Water Closet (toilet) requirements have separate gender columns for most occupancies, but then the Business B occupancy is organized differently. My client has a small restaurant with an occupant load of 35. This qualifies as B occupancy, not A-2 (303.1.1). Can the two required water closets be in the same unisex bathroom? A toilet and a urinal? Under 40 occupancy, only 1 lavatory (sink) is required.

I would say no, you are required to provide fixtures for each sex and both would be required to be handicap accessible. If these two toilets were next to one another you could label them as unisex and only make one of them handicap accessible, but its my understanding that you will still need to two toilets

I now see 403.2 requiring separate facilities for each sex (gender), which suggests the answer is no. How do unisex facilities fit into this construct?

Thanks for your reply. You anticipated my next question. Which was to offer one ADA Unisex, and one non-ADA unisex bathroom.

what version of the code are you working under?

You could easily do this in California. There is an exception specifically for M and B less than 50 occupants. No idea where you are.

Section 2902.2 of the 2018 IBC list the exceptions for single facilities

Check the plumbing code table as to how many seats you are providing, it indicates the minimum number of fixtures required.
Also if serving alcohol the license may require urinals.
