Tucson regulates building setbacks through the Unified Development Code, with requirements varying by zoning district. The UDC Table 6.3-2 establishes minimum front, side, and rear setbacks for each zone. Typical residential setbacks in R-1 zones are 20 feet front, 5 feet side, and 20 feet rear. Corner lots and lots with specific overlays may have different requirements.
Setback measurements are taken from the property line to the nearest wall or structural element. Covered porches, patios, and eaves may have reduced setback requirements. The UDC allows minor setback modifications through the Board of Adjustment for hardship cases. Accessory structures (sheds, carports) often have reduced setback requirements compared to the primary structure. Swimming pools and spas have their own setback rules separate from building setbacks.
Building within required setbacks without a variance results in a stop-work order and potential structure removal. Unpermitted construction discovered during a property sale can delay or prevent closing.
