Which rules apply in Blackwood?
Commercial and above-shop to HMO in Blackwood 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:
- Landlords must register with Rent Smart Wales, and those who manage their own lets need a Rent Smart Wales licence.
- 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.
- Council HMO standards and the fire risk assessment set detection, fire doors and escape routes.
