What is a planning or building regulations application?

Planning permission decides whether a project can be built; building regulations decide how it must be built. Most extensions, lofts and conversions need building regulations approval even when planning permission is not required.

Questions about planning and building regulations applications in County Antrim
What about shared walls in County Antrim?
Northern Ireland has no Party Wall Act. Work on shared walls relies on agreement with the neighbour and common law, so we agree the arrangements in writing before work starts.
What is a certificate of lawfulness?
A certificate from the council confirming that a project is permitted development. It is optional but useful when selling the house.
How long does a planning decision take?
Councils aim to decide most householder applications within 8 weeks.
What happens if I build without approval?
The council can take enforcement action, and missing approvals cause problems when selling. It is always better to get approvals first.
