Which rules apply in Abergavenny?
Here is what usually applies to a Abergavenny job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 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.
- England’s national room sizes do not apply in Wales; councils set their own room standards.
