If you rent out a property to several people and they each have an individual tenancy agreement with you, the property is classed as House in Multiple Occupation for Council Tax purposes.
Os ydych yn rhentu eiddo i nifer o bobl a bod gan bob un gytundeb tenantiaeth unigol gyda chi, mae'r eiddo'n cael ei ystyried yn Dŷ Amlfeddiannaeth at ddibenion y Dreth Gyngor.
