What Is The Unified Development Code?

The Unified Development Code (UDC) is a document that consolidates all development-related regulations including zoning requirements, subdivision regulations, design and development standards, and review procedures.

The UDC has several advantages over maintaining separate zoning and subdivision ordinances. First, it avoids overlapping, conflicting, or inconsistent requirements by providing one source for all standards and approval procedures. Second, the UDC is simpler for customers to use since they only need to become familiar with one set of standards. Finally, by integrating all types of development, the UDC offers a more a more flexible and comprehensive approach to design, which leads to a more consistent treatment of different types of development.

The UDC was effective on July 10, 2014.
