OFFICES AND PUBLIC BUILDINGS

Offices and public buildings may be allowed to have only one bathroom, sub­ject to the size and use of the building. Refer to Figure 9.2, line number 6, for a complete description of possible options in using a single bathroom. The table in Figure 9.8 shows you sizing information for offices and public build­ings where multiple bathrooms are used. Feel up to another sizing example? Well, let’s try a couple with the table in Figure 9.8.

Okay, assume that the public building we are working with will be rated for 75 people. What are the fixture requirements? We will need two toilets in the male restroom and three in the female restroom. How many lavatories are required? Two lavatories are needed in the male restroom and three are re­quired in the female restroom. One drinking fountain is required, but others may be required if the building has more than one floor level, since a fountain is required on each floor of the building. That wasn’t too hard, was it? Now let’s try an example with a larger occupancy load.

In this example, assume that there will be 250 occupants. The amount of water closets needed in the male restroom is four. How many are need in the female restroom? Looks like 5V2 toilets, right? Well, it is, but you have to round up to the next nearest whole number. In other words, you would need six toilets in the female restroom. What are the needs for lavatories? The male restroom requires four lavatories, and the female lavatory need is six. How many drinking fountains are needed in a building that has only a single floor? Three fountains are required.
