This alternate basis shall be included in the special stipulations and conditions section of the certificate of occupancy issued for that structure pursuant to section 110 of the building code. For accessibility requirements, see "Chapter 11, Accessibility" of the building code.

    Exception: Facilities are not required in buildings less than 100 square feet in area if fixtures are available within 500 feet of the building.

Fractional numbers resulting from applying the fixture ratios of Table 403.1 shall be rounded up to the next whole number. For calculations involving multiple occupancies, such fractional numbers for each occupancy shall first be summed and then rounded up to the next whole number.

    Exception: The total occupant load shall not be required to be divided in half where approved statistical data indicates a distribution of the sexes of other than 50 percent of each sex.

    403.1.2Family or assisted-use toilet and bath fixtures.
