Zoning Code

City of Tucson Zoning Code

The City of Tucson uses the Unified Development Code (UDC) as its Zoning Code for development. 

The UDC applies to all development and uses of land within the City of Tucson.

The UDC is detailed in three documents:

  1. The Unified Development Code - the primary document
  2. The UDC Administrative Manual - application requirements, fees, review procedures
  3. The UDC Technical Standards Manual - engineering related site standards, historic preservation guidelines, etc.
