The Unified Development Code (UDC) is a document that consolidates all development-related regulations including zoning and land use, subdivisions, 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 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.

Finding Information in the UDC

The UDC is organized into 12 articles that cover zoning districts, land uses, development standards, signs, and procedures. See the UDC Introduction for a summary of each article.

Amendments and Updates

The Unified Development Code has been amended and updated since its adoption in June 2014. Amendments keep the UDC relevant with changes that reflect the latest thinking on land use and development. Omnibus updates are made to eliminate unclear language, correct errors, and update content based on interpretations and practices of the department.

Tree Preservation and Mitigation

On November 17, 2020, the City Council adopted amendments to UDC Section 5.2.3, Tree Preservation and Replacement. The amendments revise the method of inventory for multi-family and non-residential development, increase incentives for preserving Cross Timbers Oaks, and add important administrative provisions.  Also see the list of protected and prohibited tree species in the UDC User's Guide.  A proposed rate increase to the Tree Replacement Fund for mitigation was tabled indefinitely by the Council.

UDC Amendments Under Consideration

Amendments to the Unified Development Code may be considered at any time the City Council, Planning and Zoning Commission, or staff of the Planning and Development Services Department deem it advisable.  The following staff presentations chronicle the origins and evolution of various amendments currently being discussed.
