Which rules apply in Isleworth?
Here is what usually applies to a Isleworth job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- Mandatory HMO licence for 5 or more people in 2 or more households (since October 2018); councils can add additional licensing for smaller HMOs.
- 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.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
