An HMO extension adds space to a shared house, usually a ground-floor bedroom with ensuite or a bigger communal kitchen. In Carlisle, a town of around 80,000 people in Cumbria, the work is planned around the HMO rules for England and the council’s written HMO standards. With students as well as working sharers renting in Carlisle, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Carlisle?
Extensions for extra rooms in Carlisle 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.
