IBC PLUMBING FIXTURE CALCULATOR
FOR PLANNING PURPOSES ONLY
This calculator determines fixture requirements and occupant load factors using the International Building Code (IBC) 2021, referencing Tables 2902.1 and 1004.5. Per IBC standards, any calculations resulting in a fractional fixture count are rounded up. The urinal calculation is based on the maximum allowed percentage of total male water closets, which is 67% for Assembly/Educational uses and 50% for other types of occupancies. Users should be aware that local amendments and specific project conditions can change the required fixture counts, so it is important to consult a qualified professional.
