Arizona Revised Statutes Title 11. Counties § 11-1204. Subsequent changes prohibited; exceptions

A. A protected development right established under this section precludes the enforcement against the property to which the protected development right applies of any legislative or administrative land use regulation by a county or pursuant to an initiated measure that would change, alter, impair, prevent, diminish, delay or otherwise impact the development or use of the property as set forth in an approved protected development right plan, except under any one or more of the following circumstances:

B. A protected development right does not preclude the enforcement of a subsequently adopted overlay zoning classification that imposes additional requirements and that does not affect the allowable type or density of use, or ordinances or regulations that are general in nature and that are applicable to all property subject to land use regulation by the county, such as building, fire, plumbing, electrical and mechanical codes.

C. Notwithstanding any other provision of this article, the establishment of a protected development right does not preclude, change or impair the authority of a county to adopt and enforce zoning ordinance provisions governing nonconforming property or uses.

D. This article does not alter or diminish the authority of a county to exercise its eminent domain powers.
