Traditional zoning ordinances took hold a century ago to control what was built where, how densely and how tall. Those rules determine how land is used -- preventing, for example, a company from building a factory in the middle of a residential neighborhood, or someone turning their home into a retail shop. But as more cities and suburbs shift to denser, mixed-use development, they're bumping up against zoning regulations that may no longer make sense. We explore how different jurisdictions are rethinking the rules.
"Shaping the City" columnist Roger Lewis draws humor from height limits, zoning regulations and the "new rules" of urban design.
