Which rules apply in Sutton?
Large HMO conversions (7+ sharers) in Sutton must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Licences last up to 5 years and carry conditions on gas and electrical safety, alarms, room sizes and waste.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
