Which rules apply in Rhyl?
Extensions for extra rooms in Rhyl 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:
- 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.
- Kitchen and bathroom ratios are set in each council’s HMO standards.
