The lease shall provide that all disputes concerning the obligations of the tenant or the landlord shall be resolved in accordance with the landlord's grievance procedure. The landlord's grievance procedure shall not be applicable to disputes between tenants not involving the landlord or to grievances brought by one or more tenants on behalf of a group of tenants who purport to have a common or shared claim. The landlord's grievance procedure is not intended as a forum for initiating or negotiating policy changes between a group or groups of tenants and the landlord.
