In Arizona, your ESA housing rights rest first on state law. The Arizona Fair Housing Act (A.R.S. § 41-1491.19) treats a landlord's refusal to make reasonable accommodations in rules, policies, practices, or services as disability discrimination when the accommodation may be necessary to give you an equal opportunity to use and enjoy your home. 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.
Landlords in Bullhead City who refuse a valid ESA letter or continue charging pet fees may be in violation of the Arizona Fair Housing Act and federal law. Complaints can be filed with the Arizona Attorney General's Civil Rights Division.
