Which rules apply in Flint?
Extensions for extra rooms in Flint must satisfy national law for Wales, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- 3–6 sharers is use class C4, and in Wales changing a house to C4 always needs planning permission; only C4 back to C3 is permitted development.
- Building regulations cover structural work, partitions, drainage, fire-resisting construction and electrics; confirm with building control whether the conversion is a material change of use.
- Fitness for human habitation rules require mains-powered, interlinked smoke alarms on every storey and CO alarms where there is a gas, oil or solid-fuel appliance.
- Kitchen and bathroom ratios are set in each council’s HMO standards.
