Elfen hanfodol o'r targed yw ymrwymiad Cymdeithasau Tai ledled Cymru, gyda chefnogaeth cyllid a chymorth polisi gan Lywodraeth Cymru.  Cafodd yr ymrwymiad hwn ei amlinellu'n glir yn y Cytundeb Cyflenwi Tai a gytunwyd rhwng Llywodraeth Cymru a Chartrefi Cymunedol Cymru yn gynharach eleni.  Mae gallu'r Cymdeithasau Tai i ddefnyddio'r Grant Tai Cymdeithasol a'u hadnoddau eu hunain yn ogystal â chyfrannu mewn dulliau arloesol i ddarparu tai, megis y Grant Cyllid Tai, yn hanfodol.
A vital component of meeting the target is the commitment of Housing Associations across Wales, underpinned by both funding and policy support from Welsh Government. This commitment was clearly set out in the Housing Supply Pact agreed between Welsh Government and Community Housing Cymru earlier this year. The ability of Housing Associations to use Social Housing Grant and their own resources as well as participating in innovative approaches to housing delivery, such as the Housing Finance Grant, is essential.
