Questions about small HMO conversions (3–6 sharers) in Vale of Glamorgan
Can I keep a lounge in a small HMO?
Yes, and many councils expect some shared living space where bedrooms are at the smaller end of the size range. We plan the layout so the house works for sharers and meets the local standard.
Does a small HMO need a licence?
In England a mandatory licence is needed when five or more people from two or more households share, and smaller HMOs can need one where the council runs additional licensing. Wales still applies a three-storey test, while in Scotland and Northern Ireland every HMO needs a licence. We check the address and tell you which applies before quoting.
