Which rules apply in Penarth?
The rules below are the Wales-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Penarth before we price.
- Mandatory licence for HMOs with 3 or more storeys and 5 or more people in 2 or more households; Wales did not adopt England’s 2018 change.
- More than 6 sharers is a sui generis HMO and needs planning permission; councils such as Cardiff apply concentration limits.
- 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.
