*Table 403.1 was amended by Local Law 79 of 2016. This law has an effective date of October 26, 2016.

403.1.1 Fixture Calculations

Where separate fixture ratios are provided to male and female individually in Table 403.1, the total occupant load shall first be divided in half before the corresponding fixture ratio is applied individually to each sex. Where a single fixture ratio is provided to the total occupant load in Table 403.1, such ratio shall be applied to the total occupant load including both male and female before dividing the resulting number of fixtures equally between male and female. 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. Fixture calculations in Group B office occupancies shall utilize the total occupant load on a given floor to determine the number of fixtures required for that floor.

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.

403.1.2 Family or Assisted-Use Toilet and Bath Fixtures

Fixtures located within family or assisted-use toilet and bathing rooms required by Section 1109.2.1 of the New York City Building Code are permitted to be included in the number of required fixtures for either the male or female occupants in assembly and mercantile occupancies.

*403.1.3 Single-occupant toilet fixtures

Fixtures located within single-occupant toilet rooms are permitted to be included in the number of fixtures required by Section 403, or where applicable the 1968 Building Code, for either the male or the female occupants. Fixtures located within toilet rooms subject to the exception of Section 403.2.1 are permitted to be included in the number of fixtures required by Section 403, or where applicable the 1968 Building Code, only for that sex.

*Section 403.1.3 was added by: Local Law 79 of 2016. This law has an effective date of October 26, 2016.
