An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. Sheffield is 32 miles east of Manchester. We price extensions for extra rooms there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. Sheffield has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Sheffield?
Extensions for extra rooms in Sheffield 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:
- 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.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
