Mae prosiectau Tai yn Gyntaf wedi'u cynllunio i sicrhau bod gan yr unigolyn ddewis a rheolaeth - cânt eu hannog i ymgysylltu â gwasanaethau cymorth fel gwasanaethau iechyd meddwl neu gamddefnyddio sylweddau, ond nid yw'n ofynnol iddynt wneud hynny er mwyn cael cymorth.
Housing First Projects are designed to ensure that the individual has choice and control - they are actively encouraged to engage with support services such as mental health or substance abuse, but they are not required to do so in return for support.
