Nod y Bil yw diogelu'r stoc o dai cymdeithasol yng Nghymru rhag lleihau ymhellach, gan sicrhau ei bod ar gael i gynnig tai diogel a fforddiadwy i bobl nad ydynt yn gallu prynu na rhentu cartref eu hunain drwy'r farchnad dai. Mae'r Bil yn cyd-fynd â chamau gweithredu eraill sy'n cael eu cymryd gan Lywodraeth Cymru i gynyddu'r cyflenwad o dai.
The Bill aims to protect the stock of social housing in Wales from further reduction, ensuring it is available to provide safe, secure and affordable housing for people who are unable to buy or rent a home of their own. It complements other actions being taken by the Welsh Government to increase the supply of housing.
