aka Zoning Law
rules on Real Estate development - control density, only allow certain types ("no manufacturing", etc.)
Generative codes (Building Code) have evolved from Pattern Language-s, but are much more sophisticated generating systems. A generative code is a system of unfolding steps that enable people in a community to create a wholesome and healthy neighborhood. The steps are governed by rules of unfolding that are not rigid, but depend on context, and on what came before. The rules work in a way that is similar to the rules that nature follows to unfold an organism or a natural landscape, but these particular rules unfold a Neighborhood and its buildings.
