Red-brick Victorian terraces across the inner city with 1970s estates beyond. Northern Ireland operates its own building control and planning system, and costs are the lowest in the UK.
Common postcodes covered: BT1, BT7, BT9, BT15.
Planning and building control
Building regulations applications and planning permission in Belfast are handled by Belfast City Council. Most internal refits fall under permitted development, but new electrical circuits, structural openings, boiler installations and anything affecting a party wall need notification or sign-off before the work is signed off as compliant.
Always check whether your property sits inside a conservation area or has an Article 4 direction — both remove permitted development rights that most homeowners assume they have.
