Mae’r Rheoliadau Adeiladu yn rheoli mathau penodol o waith adeiladu ac yn sicrhau bod adeiladau’n bodloni safonau gofynnol o ran iechyd, diogelwch, lle, cyfleustra a chynaliadwyedd.
The Building Regulations control certain types of building work and ensure that buildings meet required  standards of health, safety, welfare, convenience and sustainability.
