Citizens, politicians, and planning officials have embraced the need to allow for walkable neighborhoods across North America and mixed-use is an essential component for achieving walkability. However, the term mixed-use has held different meanings in different places over the past 40 years or so.
For example, mixed-use zones have usually had to declare a primary and secondary use with both use’s development standards redundantly stacked together and the primary use, such as residential, controlling the building’s configuration, orientation and disposition — thereby marginalizing the building’s ability to effectively host other commercial or office uses. Also, a mixed-use zoning designation meant that a land owner had the right to ‘choose’ a specific use, such as either commercial or residential. While the zoning district had a mix of uses, the implementation was single-use.
