Ym mis Gorffennaf 2018, lansiodd fy rhagflaenydd Lesley Griffiths AC a oedd Gweinidog yr Amgylchedd, Ynni, Cynllunio a Materion Gwledig ar y pryd, 'Gais am Dystiolaeth' i geisio barn ar sut i wella'r ffordd y cyflawnir y gofynion o ran tai a nodir mewn Cynlluniau Datblygu Lleol (CDLlau). Roedd hyn mewn ymateb i'r safbwynt o ran cyflenwi tai a'r cyflenwad o dir ar draws Cymru, ynghyd â’r pryderon a fynegwyd gan awdurdodau cynllunio lleol a chymunedau ynghylch ceisiadau cynllunio preswyl tybiannol.
In July 2018 my predecessor Lesley Griffiths AM, the then Minister for Energy, Environment, Planning and Rural Affairs, launched a ‘Call for Evidence’ to seek views on how to improve the delivery of the housing requirements set out in Local Development Plans (LDPs). This was in response to the housing delivery and land supply position across Wales which included concerns expressed by local planning authorities and communities regarding speculative residential planning applications.
