Casa Grande, AZ Right to Farm: Agricultural Zoning Protection (2026)

Section 17.20.010 sets the purpose of the UR Zone as providing principally for single-family detached homes at very low densities while also providing for the establishment and maintenance of a wide range of agricultural uses on the same land. The section states the larger minimum lot sizes required in the zone, 54,450 square feet under Table 17.20.050, exist specifically to assure adequate area for the very-low-density residential lifestyle already present in the city and to continue allowing various forms of agricultural activity for indefinite periods of time.

Subsection B notes the UR designation can also serve as a holding classification for rural areas that may later see more intensive development. Casa Grande applies nearly identical purpose language to two other low-density residential zones: the Rural Ranch (RR) Zone under § 17.20.630 and the Suburban Homestead (SH) Zone under § 17.20.720, both of which likewise pair single-family lots with ongoing agricultural use. Section 17.20.080 backs this up operationally: if a UR-zoned property's agricultural use grows beyond normal farming, such as packing, processing, sales or auction yards, the planning director can require fencing or screening under Chapter 17.52, but the underlying agricultural use itself is not barred. Principally and conditionally permitted uses for the zone are listed in Table 17.16.030A in Chapter 17.16.
