Planning and building regulations in Gwynedd
Here is how the rules work for a planning or building regulations application in Wales. In Wales applications go to the local planning authority, and building control can be the council or a registered building control approver.
The Party Wall etc. Act 1996 applies in Wales, so notices must be served before work on a shared wall, on the boundary, or excavation close to a neighbour’s foundations.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
