Which rules apply in Penarth?
Large HMO conversions (7+ sharers) in Penarth 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:
- Councils such as Cardiff and Swansea run additional licensing for HMOs outside the mandatory scheme.
- England’s national room sizes do not apply in Wales; councils set their own room standards.
- Kitchen and bathroom ratios are set in each council’s HMO standards.
- More than 6 sharers is a sui generis HMO and needs planning permission; councils such as Cardiff apply concentration limits.
