Which rules apply in Carshalton?
Here is what usually applies to a Carshalton job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 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.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- BS 7671, the wiring standard, calls for arc fault detection devices in HMOs on new socket circuits, such as rewires and consumer unit changes.
