San Tan Valley, Arizona is an unincorporated community in Pinal County where annexation and intergovernmental agreements are governed by Arizona law and county practice. This guide explains the key terms, who enforces rules, how residents are notified, and what to expect when a nearby city or town seeks annexation or an intergovernmental service agreement. For statutory procedure and municipal authority see the Arizona Revised Statutes on cities and towns: Arizona Revised Statutes - Title 9[1].

Scope & Key Terms

Definitions and common terms used by officials and landowners in San Tan Valley:

  • Annexation - the process by which a city or town incorporates adjacent territory into its corporate limits.
  • Intergovernmental agreement (IGA) - a contract between public agencies (for example, a town and the county) to provide services or share responsibilities.
  • Petition/Notice - formal documents and public notices used to start or notify affected parties of annexation or a proposed IGA.
  • Public hearing - a required meeting where officials take testimony before approving annexation or significant IGAs.
Annexation affects local taxes, services, and zoning; affected property owners should track county notices.

Specific monetary fines for improper annexation procedure or IGA violations are not specified on the cited page.

  • Fines: not specified on the cited page.
