San Tan Valley is an unincorporated community in Pinal County rather than an incorporated city, so county government handles many of the services a city would provide elsewhere. The San Tan Mountains and San Tan Mountain Regional Park lie to the west, separating the community from the Phoenix metro core, with Queen Creek bordering to the north. Homes for sale in San Tan Valley are mostly in residential subdivisions, many with community parks and pools, plus some properties on larger rural lots at the edges.
