San Tan Valley
100K-Resident Growth Corridor Becoming Arizona's 92nd Town (July 2026)
Why People Move Here
San Tan Valley is one of Arizona's largest unincorporated communities — a ~100,000-resident master-planned-community cluster in northern Pinal County, southeast of Queen Creek. After three failed incorporation attempts (2004, 2010, 2018), Prop 495 passed in August 2025 with ~66% support, and San Tan Valley officially becomes Arizona's 92nd incorporated town on July 1, 2026. Housing is dominated by affordable new-construction single-family homes across major master-planned communities — Johnson Ranch (300-acre amenity package with public golf), Copper Basin (YMCA-anchored village), Encanterra Country Club (Shea Homes; includes the 55+ Trilogy age-restricted enclave), Pecan Creek, Skyline Ranch, Circle Cross Ranch, Ironwood Crossing, and Bella Vista Trails. The SR-24 Gateway Freeway widening begins late 2026 (~2.5 years) with Maricopa Prop 479 funding, which will meaningfully shorten the commute north to Loop 202 and the Valley core.

Is San Tan Valley incorporated? What happens in July 2026?
San Tan Valley was historically an unincorporated Census-Designated Place in northern Pinal County. Proposition 495 passed on August 5, 2025, with approximately 66% support. Pinal County formally declared appointment on September 17, 2025, and San Tan Valley officially becomes Arizona's 92nd incorporated town on July 1, 2026. Three prior attempts failed (2004, 2010, 2018) because Florence and/or Pinal County vetoed them; the 2022 passage of House Bill 2455 removed external veto authority. During transition, Pinal County Sheriff and Rural Metro Fire Department continue providing services — incorporation will not immediately change law enforcement or fire coverage.
