Please, take a trip to Istanbul sometime. While there are zoning rules, they are easily subverted by a bribe or two. The architecture looks positively ghastly in many areas because of this. On the contrary, make everything mixed use. Bottom floor (at the minimum) is business use, and above that is housing.
