Which rules apply in Weymouth?
Here is what usually applies to a Weymouth job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- Fire precautions follow a risk assessment; the LACORS Housing – Fire Safety guide (2008) is guidance, not law, but many councils base their standards on it.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
