Are there any cities with no unrelated tenant limit?

[Ethan Carbonaro]

I am very interested in maximizing the potential of co-living, but I don't want to disobey local ordinances. Are there any places which do not specify how many unrelated tenants can live in the same house? Alternatively, do you know of any cities which allow for large amounts of unrelated tenants (such as 8 or 9)?

Thanks for any and all help you can offer!
