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.
