On September 17, 2020, a Michigan Court of Appeals panel unanimously held, in Riverbrook v. Fabode, that trial courts are “… required to consider reliability of methods employed by counselor as expert, as well as her final opinion in letter that tenant required an ESA because of a disability, before determining whether owner of mobile home park had refused to make a reasonable accommodation as required by the FHA.” Riverbrook v Fabode, No. 349065, 2020 WL 5580152 (Mich. Ct. App., Sept. 17, 2020). In Riverbrook, the trial court erroneously rejected the landlord of a mobile home’s evidentiary challenges to the reliability and methods of collection of the tenant’s medical documentation to support his reasonable accommodation request for an Emotional Support Animal (“ESA”). Because of the Court of Appeals ruling in Riverbrook, Housing Cooperatives seeking information from members in reasonable accommodation requests for emotional support animals, are now permitted to ask for reliable disability-related information. Although these reasonable accommodation requests should be considered on a “case-by-case” basis, Riverbrook provides additional guidance for what information Cooperatives may seek when considering the request.
