Which rules apply in Treharris?
Small HMO conversions (3–6 sharers) in Treharris 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.
