The project is an existing assembly area in a brewery, part of a multi-use commercial building, that is changing the type of use to a space with non-fixed seating. An occupant load of 70 persons has been established. Currently, there are two washrooms with one water closet in each.
Sentence 3.7.2.2.(6) and Table 3.7.2.2.-A of Division B of the British Columbia Building Code 2012.

The local authority has determined that the number of water closets required by Table 3.7.2.2.A is cumulative for male and female. This would result in the total number of water closets required by Table 3.7.2.2.A to serve the established occupant load (based on an equal number of persons of each sex) is three, one for males and two for females.
The appellant maintains that the two water closets serving 70 persons (based on an equal number of persons of each sex), each available to each sex, is compliant. Table 3.7.2.2.A requires one water closet for 35 males; there are two provided. Table 3.7.2.2.A requires two water closets for 35 females; there are two provided.
It is the determination of the Board that the required number of water closets from Table 3.7.2.2.A is cumulative, resulting in a total of three.
Sentence 3.7.2.2.(1) indicates that the occupant load is equally divided between males and females unless the portion of each sex can be reasonably determined. In this circumstance, it has been determined to be 35 males and 35 females.
In the application of Table 3.7.2.2.A, a total of three water closets is required.
The Code uses the total number of occupants to determine the total adequate number of water closets.
