For most of us in the Main Street revitalization field, addressing the inadequacies of our local zoning code has become increasingly important. For instance, local zoning may forbid certain land uses, such as residential units on upper floors, and it may lack the necessary building design standards to ensure that new construction fits in and complements the existing building fabric. When it comes to dealing with the design of new buildings, Main Street communities may develop design guidelines or adopt design overlay districts as additions to the local zoning code. Design guidelines and design review procedures, especially if they are mandatory, can effectively ensure that new buildings contribute to the district's pedestrian orientation and overall sense of scale and urban design.

However, design guidelines used today by many Main Street communities often focus exclusively on the rehabilitation of existing historic commercial buildings rather than including new construction. And, often, their design review procedures, which require builders and developers to seek project approval from a review commission, often lengthens the time it take to get a building project started. More often than not, a design review process may not always guarantee that the best building design is built since the goal of most design guidelines is to keep the worst buildings from being built.

So, what does a Main Street program do when planning to reform its local zoning code? How can we make zoning more effective when dealing with new construction and in maximizing the number of land uses in Main Street districts? How do we really know what is allowed and not allowed?
