Zoning Codes


The Unified Development Code & Supporting Documents – the Administrative Manual and the Technical Standards Manual – went into effect on January 2, 2013. These documents replaced the Land Use Code, Development Standards, and the development review procedures in Chapter 23A of the Tucson Code.

Unified Development Code - includes the City’s zoning and subdivision standards

Administrative Manual - is a supporting document of the UDC and includes the application submittal requirements, development review fees, and the City Development Review Committee procedure

Technical Standards Manual - is a companion document to the UDC and the Administrative Manual and includes the Historic Preservation Zone design guidelines and engineering related site standards, such as solid waste collection, street design, and detention/retention standards.


Zoning Interpretations/Determinations

The Zoning Administrator renders the final decision, interpretation/determination on the matter when questions occur concerning the content or application of the Unified Development Code (UDC) or the Land Use Code (LUC), whichever is applicable.
