Mae’r fersiwn hon o'r ddarpariaeth hon yn rhagolygol.![]()
Defnyddir y term darpariaeth i ddisgrifio elfen ddiffiniadwy mewn darn o ddeddfwriaeth sy'n cael effaith ddeddfwriaethol – megis Rhan, Pennod neu adran. Mae fersiwn o ddarpariaeth yn rhagolygol naill ai:
Gall Gorchmynion Cychwyn a restrir yn y blwch 'Newidiadau i Ddeddfwriaeth' fel rhai sydd heb eu gwneud eto ddod â'r fersiwn ragolygol hon i rym.
Deddf Diogelwch Adeiladau (Cymru) 2026, Adran 21 yn gyfredol gyda’r holl newidiadau y gwyddys eu bod mewn grym ar neu cyn 10 Awst 2026. Mae newidiadau a all gael eu dwyn i rym yn y dyfodol. Mae newidiadau a wnaed yn ymddangos yn y cynnwys a chyfeirir atynt trwy anodiadau.![]()
Efallai na fydd deddfwriaeth ddiwygiedig sydd ar y safle hwn yn gwbl gyfoes. Cofnodir newidiadau ac effeithiau gan ein tîm golygyddol mewn rhestrau sydd i'w gweld yn yr adran 'Newidiadau i Ddeddfwriaeth'. Os nad yw'r effeithiau hynny wedi'u cymhwyso eto i destun y ddeddfwriaeth gan y tîm golygyddol maent hefyd wedi'u rhestru ochr yn ochr â'r ddeddfwriaeth yn y darpariaethau yr effeithir arnynt. Defnyddiwch y ddolen 'mwy' i agor y newidiadau a'r effeithiau sy'n berthnasol i'r ddarpariaeth rydych yn edrych arni.
