In Ohio, your ESA housing rights rest first on state law. Ohio landlords are independently bound by ORC 4112.02(H) and OAC 4112-5-07(C), which prohibit extra charges for an "animal assistant." 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 North Canton who refuse a valid ESA letter or continue charging pet fees may be in violation of Ohio Revised Code Chapter 4112 and federal law. Complaints can be filed with the Ohio Civil Rights Commission.
