Which rules apply in Bristol?

Under the Renters’ Rights Act, civil penalties reach £40,000 for offences such as running an unlicensed HMO.
3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
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.
Where the building regulations apply to a conversion, Part E sound requirements can apply between rooms and floors.
