Setback Rules
Sahuarita establishes minimum yard setbacks for all residential zones through Chapter 18.12 of the Town Code, with setback distances varying by zone classification from the denser suburban residential zones to the larger-lot rural zones along the Santa Cruz River valley. Rural zones such as GR-1 require setbacks of 25 feet front and rear with 15-foot side yards, while suburban residential zones like SR typically require 20-foot front, 15-foot rear, and 5-foot side setbacks. Most master-planned developments including Rancho Sahuarita follow specific plan standards approved during the entitlement process under Chapter 18.71 and Chapter 18.90, which may modify the base zoning setback requirements for individual subdivisions within the community. Corner lots require increased side-yard setbacks along the street frontage equal to the front-yard minimum for the zone.

Some RestrictionsStructure Height Limits
Sahuarita limits residential building height through its zoning code Chapter 18.12, with most residential zones capped at 30 feet or two stories for primary structures, whichever measurement is more restrictive. Accessory dwelling units that extend beyond the main house setback envelope are limited to 16 feet in height under Table 18.12-5 of the code, while ADUs within the main house setback area may match the primary structure height. Structures housing poultry or small animals are further restricted to 8 feet maximum height and must be shorter than the property fence line on lots under one acre. The general regulations in Chapter 18.07 provide limited exceptions for chimneys, antenna structures, and rooftop mechanical equipment that may project above the height limit by specified amounts.

Some RestrictionsLot Coverage Limits
Sahuarita regulates the percentage of a lot that may be covered by structures and impervious surfaces through its zoning code Chapter 18.12, with maximum lot coverage varying by zone classification to reflect differences in lot sizes and intended development density across the Town. Suburban residential zones such as SR and MR typically allow 40 to 50 percent building coverage including all roofed structures, while rural zones like GR-1 and CR have lower coverage limits in the 25 to 35 percent range reflecting their larger lot sizes and open space character. The Town also regulates impervious surface coverage through grading and drainage requirements under Chapter 18.73 and the riparian habitat protection standards in Chapter 18.65, which may further restrict overall site development beyond the building coverage calculation.
