Actually, the purpose of these zoning ordinances has nothing to do with government imposing morality. They're enacted to keep a neighborhood single family residential and to keep values up by preventing multiple families from living in one residence.

It will prevent all of the following:

1) A live-in nanny.
2) A group of college students from sharing a house.
3) A family renting a room to a boarder.
4) Taking in displaced Katrina victims.
5) etc.

I don't think there should be any restrictions as long as there is at least one bedroom and one bathroom for every two people, and those rooms meet some minimum size requirement.
