Sahuarita, AZ Building Setbacks & Zoning: Setback Rules (2026)

Sahuarita zoning code Chapter 18.12 establishes the primary development standards for rural and residential zones, including Conservation Ranch (CR), General Rural (GR-1), Suburban Ranch (SR), and Medium Density Residential (MR) zone classifications. Each zone has its own table of minimum setback distances that reflect the intended character and density of development. In the GR-1 zone, which covers much of the unincorporated feel areas within Sahuarita limits, minimum setbacks are 25 feet from the front property line, 25 feet from the rear property line, and 15 feet from each side property line, reflecting the larger lot sizes of one acre or more typical of these rural parcels. The SR zone, which is more common in newer subdivisions built in the 2000s and 2010s, typically requires 20-foot front yards, 15-foot rear yards, and 5-foot side yards on standard interior lots. Corner lots in all zones must maintain the front-yard setback distance along both street frontages, with the interior side yard following the standard side-yard requirement for that zone. Accessory structures such as detached garages, workshops, and storage buildings must meet the same setbacks as the primary dwelling, unless they qualify for the reduced ADU setback standards specified in Table 18.12-5 of the code, which governs accessory dwelling units specifically. Farm product stands permitted in rural zones must maintain a minimum 20-foot setback from the street side and a 30-foot setback from any other property line, with stand size limited to 750 square feet in the RH zone and 300 square feet in the GR-1 and SR zones. All setback measurements are taken from the property line to the nearest wall or structural element of the building, not from the curb or edge of pavement. Sahuarita allows lot development modifications under Chapter 18.85 for properties with unusual shape, topography, or other conditions that create a practical hardship when strict setback compliance is required. Applications for modifications go to the Board of Adjustment, which evaluates whether the hardship is unique to the property and whether granting relief would be consistent with the general intent of the zoning code. Master-planned communities like Rancho Sahuarita operate under specific plans approved through Chapter 18.90 that may establish custom setback standards tailored to each subdivision phase, and residents should consult their recorded subdivision plat and CC&Rs for the exact setbacks applicable to their individual lot.
