In Arizona, your ESA housing rights rest first on state law. Under the Arizona Fair Housing Act, A.R.S. § 41-1491.19, housing providers must make reasonable accommodations in rules, policies, practices, or services when necessary to give a person with a disability equal opportunity to use and enjoy a dwelling. 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.
