In Ohio, your ESA housing rights rest first on state law. Ohio Revised Code § 4112.02(H) makes it unlawful to deny or make housing unavailable because of disability, and Ohio Administrative Code rule 4112-5-07 entitles a person with a disability to keep an animal assistant in their housing. This state protection is enforced by the Ohio Civil Rights Commission 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 Centerville who refuse a valid ESA letter or continue charging pet fees may be in violation of ORC § 4112.02(H) and federal law. Complaints can be filed with the Ohio Civil Rights Commission.
