In Arizona, your ESA housing rights rest first on state law. Under A.R.S. § 41-1491.19, housing providers must make reasonable accommodations for people with disabilities, and A.R.S. § 41-1491 expressly defines an assistance animal to include animals that provide therapeutic or emotional support. This state protection is enforced by the Arizona Attorney General's Civil Rights Division and remains fully active. The federal Fair Housing Act (42 U.S.C. § 3604) provides the same obligation, and that statute has not changed.
