Answer 1

Yes a standard based on observation. Check the "Standard Handbook for Civil Engineers in the Environmental ENgineering section. In the reading there will be tables for most applications such as a hotel which would be based on observation nothng scientific. Or you can use common sense, which always comes in handy, for instance the restruarant, coffee shop and bar can use the same restrooms and for males should have 3 to 4 commodes and 1.75 times as many urinals. For females I would use six commodes. You may ALso want to check out ASCE's (American Society of Civil Engineers) Web site.

Answer 2

In the United States, the main governing code body is the International Code Council. In your case the code would be the International Plumbing Code, specifically Chapter 4 on "Fixtures". There you will find all that you need for all your different space occupancies.
